Station Way Detour In Ashton

Added: (13 Mar 2017)

Construction Phase S2, the widening of the R60 turn-off towards Swellendam, is underway in Ashton.

The intersection of the R60 with Industria Road needs to be closed for a couple of months in order to install the services and build the road layers at the intersection. From 20 March 2017, the traffic will be diverted to Station Way and along the railway tracks. The following diagram indicates the detour and the road section that will be closed.

Detour via Station Way from 20 March 2017 for two months


All the properties in the industrial area will be affected by the intersection closure. The most notable businesses that will require visitors to follow the detour are the Ashton Traffic Department and the SPCA.

Services Installation In Long Street And Closure Of Market Street

Added: (10 Mar 2017)

The installation of services in Long Street is continuing. This bulletin contains a summary of the next phase of road closures.

1. Closure of Market Street intersection: This closure will be implemented on Tuesday, 14 March 2017, and will be in place for several weeks.
2. Phase 1: Wednesday, 15 March 2017: Sleeve installation across Kohler Street (southern leg of intersection with Long Street). Note that no alternative vehicle access will be possible!
3. Phase 2: Thursday, 16 March 2017: Sleeve installation in northern half of Long Street at Kohler Street intersection.
4. Phase 3: Friday, 17 March 2017: sleeve installation in southern half of Long Street at Kohler Street intersection.

The following diagram indicates the different phases.
Road closures due to services installation


During Phase 1, there will be no vehicle access to the southern part of Kohler Street. Residents will have to make arrangements to park their vehicles outside the closed area before 07:00 on Wednesday, 15 March 2017. The closure is expected to be in place until nightfall.

During Phases 2 and 3, a short stop-go will be in place in Long Street to allow alternating two-way traffic.
For the next few weeks, the closure of the intersection of Market Street with Long Street requires vehicles to find an alternative route to Bath Street and then turn into Market Street.

Traffic Violations

Added: (08 Mar 2017)

The problem of people ignoring traffic signs, especially the one-way signs, is becoming more serious.

The construction team is reporting more and more incidents of drivers ignoring traffic signs and displaying dangerous behaviour. Vehicles that are speeding and violating traffic signs, especially the one-way signs, are a serious safety risk to everyone on the street.

The following locations are especially dangerous:

1. The eastbound one-way section between Voortrekker Bridge and Church Street in Montagu: This section is a one-way section and there are residents who continue to drive in the wrong direction. Please be patient – instead of driving into oncoming traffic, please take the correct ring-road route to get to your destination.

2. The eastbound one-way section between Du Toit Street and Cross Street in Montagu: This section is across from the primary school and has a lot of pedestrian traffic. Please do not be a safety hazard – slow down and follow the ring-road one-way direction.

The situation has become so serious that the construction team has notified the local and provincial traffic departments to assist with law enforcement.

Services Installation In Long Street (From Kohler St To Market St)

Added: (02 Mar 2017)

As part of the new electrical services being installed in Long Street, cables need to be laid from the mini-sub at Kohler Street to Market Street.

In order to do the installation, several road closures need to be implemented. The following list details the various phases and accompanying road closures:

1. Phase 1: The initial date of 3rd March has been changed - new date will be advised at a later stage:
a. Sleeve installation in southern half of Long Street at Kohler Street intersection.
b. Sleeve installation across Market Street (at intersection with Long Street).

2. Phase 2: Monday, 6 March 2017: Sleeve installation across Du Toit Street (northern leg of intersection with Long Street).
3. Phase 3: Tuesday, 7 March 2017: sleeve installation in northern half of Long Street at Du Toit Street intersection.
4. Phase 4: Wednesday & Thursday, 8 & 9 March 2017: sleeve installation in southern half of Long Street at Du Toit Street intersection.

The following diagram indicates the different phases:
Road closures due to electrical cable installation


During Phases 1, 3, and 4, a short stop-go will be in place in Long Street to allow alternating two-way traffic.
During Phase 1, the access to Market Street from Long Street will be closed. Vehicles will have to find an alternative route to Bath Street and then turn into Market Street.
During Phase 2, the access to Du Toit Street from Long Street will be closed. Vehicles will have to find an alternative route to Bath Street and then turn into Du Toit Street.

The public’s attention is drawn to the notice published on 17 January 2017 about the one-way ring-road system from Du Toit to Cross Street. The construction team urges the public to drive slowly and obey road signs indicating the one-way direction.



Closure Of R60 & Zandvliet Road Intersection

Added: (21 Feb 2017)

The construction team is ready to construct the southern half of the intersection of Zandvliet Road with the R60 in Ashton. The northern half of the intersection (at Unipack) was built last year.

In order to build the intersection, the intersection needs to be closed to traffic during March and April 2017. The western end of Zandvliet Road will therefore not be accessible during this time. Vehicles will have to drive to the other end of Zandvliet Road (at km 17.3, across from Bruwer St) to access any properties along Zandvliet Road.

The following picture indicates the construction zone and the alternative access to Zandvliet Road.


Road closures in Du Toit St (from 15:00 on Friday, 10 Feb, to Sunday night)




Closure of Du Toit Street at Low Water Bridge

Added: (09 Feb 2017)

The northern leg of the intersection of Long and Church Streets will remain closed until tomorrow evening.
As a result of the installation of the stormwater pipes in Du Toit Street, part of the road surface is currently gravel. During the coming weekend, the gravel surface will be sprayed with a binding product in an effort to reduce dust. A section of Du Toit Street will therefore be closed to all traffic from 15:00 on Friday, 10 February 2017, to Sunday night. The affected road section is shown in the following diagram.


Road closures in Du Toit St (from 15:00 on Friday, 10 Feb, to Sunday night)


It is important to note that absolutely no pedestrians or vehicles will be allowed in the construction zone. All school children or other pedestrians usually crossing the river using Du Toit/Eyssen Street need to adjust their routes. Pedestrians can use Kohler Street and Church Street to cross the river during the construction time.



Electrical Services Installation in Long Street (From Barry St to Kohler St)

Added: (09 Feb 2017)

As part of the new electrical services being installed in Long Street, cables need to be laid from the mini-sub at Kohler Street to Barry Street.

In order to do the installation, several road closures need to be implemented. The following list details the various phases and accompanying road closures:
1. Phase 1: Monday, 13 February 2017: sleeve installation in southern half of Long Street at Kohler Street intersection.
2. Phase 2: Tuesday, 14 February 2017: sleeve installation in northern half of Long Street at Kohler Street intersection.
3. Phase 3: Wednesday and Thursday, 15 & 16 February 2017: sleeve installation across Kohler Street (northern leg of intersection with Long Street).
4. Phase 4: Monday, 20 February 2017: sleeve installation across Church Street (northern leg of intersection with Long Street).


Road closures due to electrical cable installation


During Phases 1 and 2, a short stop-go will be in place in Long Street to allow alternating two-way traffic.
During Phase 3, the access to Kohler Street from Long Street will be closed. Vehicles will have to find an alternative route to Bath Street and then turn into Kohler Street.
During Phase 4, the access to Church Street from Long Street will be closed. Vehicles will have to find an alternative route to Bath Street and then turn into Church Street.
Cables will also be laid in the northern sidewalk of Long Street between Barry Street and Kohler Street. The construction team will visit the adjoining properties individually to inform residents of any disruptions to their accesses.



Services installation update and ring-road implementation

Added: (17 Jan 2017)

The construction team will continue to install services as part of Construction Phase M2A (the eastbound lane between Du Toit and Cross Street). The work between Du Toit and Cross Streets will commence on 18 January 2017.

The eastbound ring-road system will therefore be implemented between Du Toit and Cross Street. This means that traffic will only be allowed to travel towards Barrydale in this section. Parking on the left-hand side against the works area will be allowed in front of the school between 06:30 and 07:30 and 12:30 and 14:30.

The Long Street intersections with Du Toit, Market, and Cross Streets will remain open most of the time. However, these intersections will have to be closed completely at some stage in order to install the services across the intersections. The public will be notified before the intersections are closed.

The first phase of the installation of the stormwater pipe in Du Toit Street (between Long Street and the Kingna River) is complete (refer to Bulletin dated 9 September 2016) In order to accommodate the school traffic better, Phase 2 has been postponed until further notice.



Construction update and holiday arrangements

Added: (07 Dec 2016)

The major blasting in Cogmanskloof is complete. The road closures through Cogmanskloof on Tuesdays and Thursdays will therefore be cancelled until further notice.
However, small blasts may still be required sporadically at the new bridges and for the installation of services in the kloof. The public will be notified of any smaller blasts and subsequent road closures via the media.


View of main blasting site at Keurkloof


Ashton and Cogmanskloof update
The northern half of the R60 in Ashton, between Ashton Cellars and Middle Street, is complete. The new road surface is asphalt and makes for a very smooth ride!
The northern half of the road between km 20.4 and km 21.8 (from Hodges Bridges to Boy Retief Bridge) is almost complete with the surfacing layer being applied this week. The road in this section is being sealed with a Cape Seal – a strong, long-lasting surface. The road past the main blasting site (from km 24.0 to km 24.8) is not yet complete, but the temporary bypass has been surfaced to provide a better driving experience through the holiday period. Two-way traffic will be possible in this section and therefore the stop-go will not be required here during the holidays.

Montagu update
The road layers have been completed up to the base layer in the two work zones in Montagu. The asphalt surfacing required in certain sections for traffic will be done before the year-end break. The installation of services is mostly complete in these sections as well. The new streetlights that have been installed in Montagu will be operational in the holidays.


Laying of bitumen-treated base layer in Long Street, Montagu


While two-way traffic will be in place in Montagu before 16 December 2016, the road will not be completely open to normal traffic. There will be a level difference between the two lanes in Long Street, from Voortrekker Bridge to Church Street, and from Cross Street to the Van der Merwe Bridge. There will be delineators in place in the middle of Long Street to prevent vehicles from crossing the centreline, except at designated points where ramps will make it possible to cross the street.

The ring-road system will be suspended during the holidays. Van Riebeeck Street will therefore return to two-way traffic along its entire length, as it was before construction started.
The sidewalks of Long Street will not be complete and pedestrians are urged to pay attention to negotiate uneven patches.
The northern halves of the concrete approach slabs at Van der Merwe Bridge are also complete. These slabs, in conjunction with other protection measures still to be built, will protect the road from flood damage. The required asphalt surfacing in this section will be done before 16 December 2016.

Update on the new bridges
The foundations for five of the seven temporary piers for the new Ashton Bridge (km 17.8) are complete. Both the eastern and western abutments are almost ready for the installation of the deck support. The focus early in the newyear will be to complete the temporary piers from the western side before deck construction can commence. The public can expect to see big changes during 2017.


Ashton Bridge temporary works


The southern abutment for the new Boy Retief Bridge (km 22.2) is 75% complete. The current focus is on the completion of the two piers. The construction sequence dictates that the bridge deck be built in three phases, from south to north. The excavations for the foundations and abutments of the new Voortrekker Bridge are complete. The construction of the western foundations, piers, and abutment has commenced and will continue into 2017. Electric pumps have been installed to reduce the noise of keeping the works area dry.


Foundations and abutments at Voortrekker Bridge


Stop-go’s during holidays
Most of Montagu’s Long Street and the Cogmanskloof Pass will be open to two-way traffic during the holidays. However, at some points, the road will be too narrow to allow two-way traffic. Short stop-go zones will be implemented at the following locations during the holiday season:
• At Boy Retief Bridge (at km 22.2 in Cogmanskloof)
• At Voortrekker Bridge (on the western end of Long Street).
Travellers can expect waiting times of up to 10 minutes at each stop-go.
Arrangements for the year-end holidays
The construction team will have a small team on site throughout the holidays. This team will ensure that the road remains safe by, among other things, fixing potholes, and maintaining the road signs.
To report any problems, please call 073-553-2171 or 071-649-0665.
HAPPY HOLIDAYS from the Construction Team !!

Services installation between Du Toit and Cross Streets

Added: (19 Oct 2016)

As part of Construction Phase M2A (the eastbound lane between Du Toit and Cross Street), several services need to be installed. Short-term road closures will therefore be implemented between Du Toit and Cross Street during the next few months. The following paragraphs contain more details about the different services and resulting road closures.

Installation of Temporary Potable Waterline (Du Toit to Cross Street)

In order to facilitate the installation of the stormwater system and the new 110mm potable water main in Long Street, a temporary waterline is going to be installed from Du Toit Street to Cross Street.

The temporary waterline will be a 63mm HDPE pipeline that will be connected to the existing water main in Long Street. The temporary pipeline will be installed on top of the sidewalk (pavements) and will supply all the respective properties along Long Street between Du Toit Street and the Van der Merwe Bridge.

The installation will require that the water supply to the houses and businesses on Long Street be shut down. This will be done over several days during the next 2 weeks and the water will be off for several hours each time. SMS’s will be sent by the municipality to notify the public in advance of the water disruptions.

Planned dates: 19 Oct 2016 to 26 Oct 2016

Relocation of Ashbury Rising Main (Market to Cross Street)

In order to relocate a section of the 250mm Ashbury water main, the northern lane of Long Street between Market and Cross Streets will be closed.

The installation of the pipeline across the Cross Street intersection will be done during a night shift. During this time, the intersection will be closed but reopened the next morning.

During the connection of the new waterline, the intersection of Long and Market Streets (and ±20m of Market Street) also needs to be closed (±2 days). Access to properties will be maintained at all times.

This work will not cause water disruptions to the public.

Planned dates: 20 Oct 2016 to 3 Nov 2016

Stormwater Installation (Du Toit to Cross Street)

The installation of the stormwater pipes in Long Street between Du Toit and Cross Streets will start soon. The full road section will not be under construction; instead, short sections of the eastbound lane (+-70m each) will be closed at a time in order to lay stormwater pipes.

The short work sections will reduce the impact of the road closures on the public and businesses. On completion of each section, it will be reopened to traffic.

Access to houses and businesses will be restricted, but maintained by pedestrian walkways or alternative arrangements. The residents will be informed individually of any changes or restrictions to their accesses.

Planned dates: 24 Oct 2016 to 6 Dec 2016



Update: Long Street Upgrade & installation of the Stormwater Pipe

Added: (16 Sep 2016)

A. Status of Progress - Long Street Upgrade:

The construction team has been given approval to work longer hours in Montagu.
One of the main advantages of the extended working hours will be the opening of Long Street for two-way traffic over the Christmas holidays.

The following will be the new working hours:
Monday to Friday: 7am to 6pm
Saturdays: 7am to 5pm
Sundays: 7am to 1pm (mostly preparation work with smaller teams)

The construction team apologises in advance for the inconvenience and will endeavour to keep noise and other disruptions to a minimum.

B. Installation of the Stormwater Pipe in Long Street:

The section from Barry Street to Church Street will commence on Monday next week. (19 September) The intersection of Barry and Long Street will therefore be closed. No traffic will be able to turn from Barry Street into Long Street and vice versa. The one-way ring road system will continue to be in operation and will allow traffic via Van Riebeeck Street to access the western end of Long Street.

Stormwater installation in Du Toit Street: Phase 1 (12 Sep - 4 Oct)

Added: (9 Sep 2016)

The installation of a new stormwater pipeline in Du Toit Street (between Long Street and the low water bridge) will commence soon. The installation has been divided into three phases in order to accommodate the traffic around Spar and Montagu Primary School.

CONSTRUCTION ZONE: PHASE 1
During Phase 1 of the installation, the portion of Du Toit Street between the low water bridge and the gate from the Spar overflow parking area will not be accessible to the public. Phase 1 is scheduled to commence on 12 September 2016 and should be complete by 4 October 2016.

The following diagram shows the construction zone during Phase 1:

Figure 1: Phase 1 of Du Toit Street stormwater installation


NO ACCESS FOR PEDESTRIANS OR VEHICLES


It is important to note that absolutely no pedestrians or vehicles will be allowed in the construction zone. All school children or other pedestrians usually crossing the river using Du Toit/Eyssen Street need to adjust their routes. Pedestrians can use Kohler Street and Church Street to cross the river during the construction time.

The gate to the sports fields will be inaccessible during Phase 1. Only pedestrian access will be possible to the sports fields via the other school entrances.

Two-way traffic flow will still be possible in the upper portion of Du Toit Street.

Blasting at Van Riebeeck Street

Added: (27 Aug 2016)

The blasting in Cogmanskloof is progressing well. 90% of the required blasting at Aasvoëlkrans is complete, and the blasting at the western intersection of the R62 with Van Riebeeck Street will commence next week. The hard rock at the western end of Van Riebeeck Street will be blasted in sections over the next 2 months. During this time, blasting will alternate between Aasvoëlkrans and Van Riebeeck Street.

When the blasting is undertaken at the western end of Van Riebeeck Street, the traffic will not be allowed within 300m of the intersection. This means that the traffic heading towards Ashton will be stopped about 600m before the intersection, as indicated in Figure 1. Traffic wanting to travel to Montagu’s town centre will be redirected at Brink Street.


Figure 1: Traffic restrictions during blasting at Van Riebeeck Street


Construction personnel will be positioned at critical points to assist traffic. We appeal to the public to cooperate with these officers and to only park in the areas indicated by these officers.

This bulletin contains a brief description of the revised construction phases in Montagu, and the reasons for such revision.

1 Phases of construction in Montagu


Due to several factors, the construction phases in Montagu have been adjusted. Phases A and C have been merged to form a new, extended, Phase A. Similarly, Phases B and D have merged to form a new, extended, Phase B. The middle section, formerly Phase E, will now be slightly shorter and called Phase C. See Figure 1 for details.

At the moment, the LHS of Phase A (M2A) and the LHS of Phase B (M2B) are under construction.

Figure 1: Revised phases of construction in Montagu


2 Revised Programme


Due to various reasons, the construction of Phase A and Phase B have taken much longer than anticipated. This slow progress directly impacts the programming of the other phases in Montagu. The subsequent result is that the construction of Long Street will only be completed by the end of 2017.

The latest planned construction programme in Montagu is as follows:
• Phase M2A (LHS): currently under construction. Completion expected in November 2016;
• Phase M2B (LHS): currently under construction. Completion expected in December 2016;
• Phase M2C (LHS): construction to follow completion of M2A and M2B, therefore construction expected from December 2016 to March 2017;
• Phase M3A (RHS): construction to follow completion of M2C, therefore construction expected from March 2017 to July 2017;
• Phase M3B (RHS): construction to follow completion of M2C, therefore construction expected from March 2017 to August 2017;
• Phase M3C (RHS): construction to follow completion of M3A and M3B, therefore construction expected from August 2017 to December 2017;

Please note that the durations stated may change as a result of adverse weather conditions or unforeseen physical conditions encountered during the construction.

The construction team understands the frustration and inconvenience the road construction has on the residents of Montagu. The construction team again commits themselves to minimising the disruption to businesses and private residents. Each property will be visited individually by the construction team before construction commences in a section. The applicable construction process and consequences will be explained. If any member of the public has concerns or queries, they can contact the Montagu Liaison Committee (MLC): ronel@montagu.org.za

Delays in Montagu


There are several factors that have slowed down the progress of construction within Montagu.

New pipeline to Ashbury water reservoir

One of the major unforeseen tasks that came to light was the replacement of the asbestos cement water pump line in Long Street between Market Street and the Van der Merwe Bridge.

The existing pipeline, supplying water to the Ashbury reservoir from the waterworks on the southern side of Montagu, was too shallow and brittle for the construction of the road to continue. The waterline has now been replaced with a new 250mm uPVC pipe from Cross Street to the Van der Merwe Bridge. The extension between Cross Street and Market Street will be done in due course.


Figure 2: Installation of water main to Ashbury reservoir


Saturated soil conditions

The high water table in the western part of Long Street is a hindrance to construction. The ground is saturated with water in the area where roadworks is supposed to be underway. Not only do the two rivers contribute to the high water table, but the irrigation water supplied by the leiwater channels also contribute to ever seeping groundwater.

Even though subsoil drains have been installed and open drainage channels have been dug, the ground was still too wet for construction vehicles to build the lower road layers. Additional subsoil drains have now been installed to drain the excess water.


Figure 3: Installation of subsoil drains


Review of stormwater design

Originally the intention was to utilise the leiwater channels on the southern side of Long Street to disperse with stormwater. However, after further investigation, it was decided that due to the negative impact this may have on the future development of some properties, the risk of polluted water being discharged onto private properties and the fact that many channels are leaking, the stormwater design should be reviewed and the channels should be disregarded in the stormwater design. This resulted in a re-design of the stormwater pipes in Montagu.

Both the design, and the procurement time for larger pipes, resulted in substantial delays of construction. The significant benefit of the upgraded stormwater system should be clear to the town of Montagu. Less flooding and a more efficient stormwater system can be expected once construction is complete.

Additional services to be installed– watermain in Long Street

While new electrical services were planned for implementation in Montagu, the replacement of the existing watermains were not included in the project. However, the existing water supply network is old and pipe bursts are quite common. In addition, the main pipe and connections are so close to the road surface that it will interfere with the construction of the new road layers.

It was therefore decided that a new watermain will have to be installed along Long Street. This is additional work that was not part of the original scope and it subsequently contributes to the extended period of construction in Montagu.

Furthermore, many of the existing water and electricity connections between the main supply and the private properties are too close to the road surface. The Langeberg Municipality has assisted in relocating most of these connections in the current work areas so that it will be deep enough for the new road layers to be constructed over it. However, the fact that Long Street is constructed in half-widths means that only one half of the connections can be altered at a time. The fact that water and electricity need to be supplied to all properties means that temporary pipes will be used in the coming phases and this also influences the construction programme.

Even though the installation of a new watermain will result in a longer construction period in Montagu, the long tem benefit to the town infrastructure is immense. The new watermain will supply the residents of Long Street of water for a long time, with minimal maintenance required by the municipality.

Deeper excavations, narrow working space

A direct result of the larger pipes that will be installed in Montagu as part of the new stormwater design is the deeper excavations that are required to lay the pipe. The deeper excavations need additional support to prevent the sides of the excavations to cave in. This adds to the workload and results in slower progress than originally anticipated.


Figure 4: Shoring required for deeper excavations


Additionally, the wider excavations required to accommodate the larger pipes result in less space left over within the half-width to store material. This means that pipe sections, stone, sand etc. all need to be delivered in small quantities, or that construction machines need to drive back-and-forth from a stockpile area to the section under construction. This all results in slower production rates and therefore a longer construction period in Montagu.


Figure 5: Narrow working space due to large excavations for stormwater pipes


No danger of delays due to financial or political reasons

The Western Cape Government Department of Transport and Public Works is providing the main source of funds for the construction project. The Langeberg Municipality is also contributing funds to a smaller extent. Fortunately, both organisations are well run and have ring-fenced funds for this project. There is no danger that the project will be delayed due to a lack of funds.

Cogmanskloof Blasting Schedule

Updated: (29 August 2016)

Here is the schedule for the blasting in Cogmanskloof and the intersection of the R62 and Van Riebeeck Street. The R62 through Cogmanskloof will be closed from 11:00 to 13:00 on the days of blasting.
When blasting at Van Riebeeck Street (only), the intersection of the R62 with Van Riebeeck Street will also be closed and traffic will therefore not be able to drive via the intersection to Long Street. Construction personnel will redirect traffic during the road closures.

Please also remember to inform tourists and guests of the blasting arrangements. Hikers and climbers should evacuate the blast danger zones before 10am. In future, confirmation of the temporary closures may be obtained by visiting this website, or by calling 071-649-0665.

Crane - Ashton Bridge

Added: (22 Apr 2016)

The Basil Read Safety Supervisor has asked us to inform the public that they do not need to be scared of the crane at the Ashton bridge. Many people are hesitant of driving underneath the crane arm in the main road of Ashton. They slow down, and even come to a stop abruptly, when they see the crane arm in the air above the road, and then subsequently block the traffic flow.

They want to assure the public that they do not need to be worried that the crane arm will break. There are many safety features built into the design that prevent unexpected failure.
The crane will not move any loads over the road without prior arrangement and traffic accommodation. However, when the crane is not loaded, its arm can turn 360ø depending on the wind direction, and it is not a safety risk.

Construction update, including Montagu construction phases

Added: (17 Feb 2016)

In Montagu, the construction of Long Street is in full swing. Activity can be seen on both the western and eastern sides of town where the left-hand side (LHS) of Long Street has been broken up and new road layers are being built.

The blasting in Cogmanskloof is also progressing well. The stop-go traffic control is protecting passing vehicles from falling rocks and providing space for the construction work. The stop-go extends from the Aasvoelkrans blasting site towards Montagu so that the existing road can be widened on the LHS. This is a temporary widening so that traffic can be accommodated when the new RHS of the road is built in this section.

Preparations and temporary works are underway at both the Ashton and the Boy Retief bridges.

Implementation of additional Stop-Go traffic control system


In order for construction work to begin between the intersection of the R60 and R62 (turn-off to Swellendam) and Boy Retief Bridge, another stop-go traffic control system will be implemented. This will be the second stop-go zone on the project and will increase the total delay affecting traffic driving through Cogmanskloof.

It is expected that the average delay through Cogmanskloof (including both stop-go zones) will usually not exceed 30 minutes. Your patience is appreciated.

Traffic movements in Montagu


During the construction period for Phases M2 and M3, a one-way traffic system will be implemented in Montagu (see Diagram 3).

Diagram 3 - Traffic Flow in Montagu - click to enlarge


Eastbound traffic, travelling from Ashton towards Barrydale, will be accommodated along Long Street and westbound traffic, travelling from Barrydale towards Ashton, will be accommodated along Van Riebeeck Street (DR1373), creating a "ring road".
At the moment, two-way traffic is still allowed on the central section of Long Street. Due to the small turning space available at the intersection of Long Street and Church Street, it is difficult for trucks to turn at this intersection. Trucks travelling from the Koo Valley or from the Montagu town centre are urged to follow the ring road instead of travelling along Church Street.
The narrow road width on the western section of Van Riebeeck Street has, in conjunction with the high speed of some vehicles, necessitated the one-way traffic direction on the western section of Van Riebeeck Street.



Speeding along Van Riebeeck Street - Speed Hump introduced

Added: (14 Jan 2016)

The construction team has noticed speeding, not only on Van Riebeeck Street, but also in Long Street and through Cogmanskloof.
One of the measures that has been taken to curb speeding is the installation of new stop-signs at several intersections. Vehicles are now required to stop when they enter Montagu from Cogmanskloof and from Barrydale. Vehicles are also required to stop at the intersection of Church Street and Long Street. Along Van Riebeeck Street, vehicles are required to stop at Eyssen Street, Kohler Street, and Church Street.

The construction team has also installed a temporary speed hump in Van Riebeeck Street this morning (at the narrowing of the road in the vicinity of Aasvoëlkrans B&B). This speed hump is very severe and vehicles basically have to come to a stop before driving over the speed hump. The construction team did not want to implement this speed hump because of how acute it is, however, after receiving continuous complaints from Van Riebeeck residents, the construction team agreed to implement this temporary speed hump. This hump is so severe that flagmen have to stand alongside the hump to warn vehicles to slow down dramatically. For this reason, this hump can only be used during the day and have to be removed from the road at night.

A long-term speed hump is being designed and will be implemented on the western side of Van Riebeeck Street. This long-term speed hump will allow vehicles to travel over it at a reasonable speed. Van Riebeeck Street, as well as Long Street, are urban zones and a 60km/h speed limit is applicable. The construction team has found that the addition of more speed limit signs do not decrease the speed of vehicles. The construction team has requested the support of the traffic department to help reduce speeding and other dangerous traffic violations. Unfortunately, their capacity is limited and they will not be able to continuously monitor Montagu and Van Riebeeck Street specifically. The construction team would like to remind the public to obey all traffic rules and be considerate to fellow road users.

Road and sidewalk widths of Long Street, Montagu


The total road width of Long Street will remain as it is now, i.e. no expropriation has been, or will be, done in Long Street. This means that the total road width, including the sidewalks, will remain as it is now. Despite the fact that the proclaimed road reserve is 15m wide, the fences and boundary walls of properties are not aligned. The distance between the property boundaries actually varies between 14.0m and 16.2m.

After the public raised their concerns about the narrow sidewalks and speeding in Long Street, the road width and sidewalk widths have been reconsidered. The client subsequently agreed to reduce the shoulder/parking bay area with 200mm so that the sidewalk width may be increased. The average sidewalk width will now be approximately 1.7m instead of 1.5m. The new typical road cross section is shown in Figure 1. The cross section is only a general guide and the actual widths of the sidewalks will vary depending on the property boundaries.

1. Road numbering and terminology


"TR31" is the abbreviation of Trunk Road 31, which is the provincial roads department's name for the piece of road consisting of sections of the R60 and R62. TR31 consists of several sections, which are indicated as TR31/1 (Trunk Road 31 Section 1), TR31/2 (Trunk Road 31 Section 2) etc. For interest, TR31/2 ends at the intersection of Long Street and Church Street in Montagu, from where TR31/3 begins.

The road is always viewed in increasing kilometre-values (similar to stake values, abbreviated with "SV"), and as such the left-hand side of the road will always be to the left when looking towards increasing kilometre-values. The left-hand side (LHS) of TR31 in Montagu (Long Street) will therefore always be the northern half of the road, which is the traffic lane driving towards Barrydale. Conversely, the right-hand side (RHS) of TR31 in Montagu will always be the southern half of the road.



2. Scope of work


The project entails the reconstruction of the road from the West of Ashton (km 15.4 of TR31/2), through Cogmanskloof, and through Montagu to the East of Montagu (km 1.4 of TR31/3). The road width through Ashton will be increased slightly, while 1.5m shoulders will be added to both the left-hand side (LHS) and right-hand side (RHS) of the road through Cogmanskloof. The road width through Montagu will remain unchanged.

The project includes the replacement of three of the existing river bridges. These bridges are at km 17.8 (Ashton Bridge, B2666), km 22.2 (Boy Retief Bridge, B2642) and km 25.8 (Voortrekker Bridge, B2466) - see Diagram 1 for the location of the bridges.

Furthermore, the bridges at km 23.59 (Billy Loftus Bridge, B2643) and km 1.24 (Van der Merwe Bridge, B2645) will remain as is apart from the erosion and scour protection that will be done. The erosion and scour protection include the construction of concrete pavements with cut-off walls on the approaches, and grouted stone pitching and rip-rap to protect the road and river banks.

The project will also include the upgrading of storm water systems, the installation of street lighting in Montagu and Ashton, the relocation and protection of existing services, and the installation of new services
