Changes to traffic signals at Main Rd / Clairvaux intersection

August 29, 2012

The existing traffic lights at the Main Road and Clairvaux Road intersection, and Main Road and the Kalk Bay Harbour entrance have been set to flashing red mode for all directions.

Motorists are obliged to treat these intersections as a 3-way stop and are requested to exercise extreme caution when traveling through these intersections.

This situation has been created as a precursor to the implementation of the signalised stop / go system south of Clairvaux Road, and to prepare road users for the pending temporary traffic management system.

The temporary traffic management system is expected to be operational early next week, but is dependent on the Contractor completing some modifications to the existing Main Road north of Clairvaux Road.

Main Road between Clairvaux and Rouxville Roads will then be opened to two-way traffic and the section of Main Road between Clairvaux Road and the Bible Institute, will start operating as a signalised stop/go system, utilising three new sets of temporary traffic signals. The existing traffic signals will be switched off at this stage.

Details of implementation :

Three sets of temporary traffic signals will be installed together with a dedicated signal controller. This will be similar to the system installed under the Phase 1 contract. The Metrorail crossing will be managed manually, by trained personnel. The boom control and flashing red lights at the level crossing will remain in place.

Each cycle of the signal timing will operate on an approximate two to five minute cycle but will be adjusted as circumstances warrant. The three cycles will be set up as follows:

1.Clairvaux Road : Left or right turning traffic into Main Road.

2.Main Road Southbound : Right turning into Clairvaux Road or straight on to Clovelly.

3.Main Road Northbound : Left turning into Clairvaux Road or straight on to Muizenberg.

In addition three variable messaging signs (VMS’s) will be erected to indicate in advance the availability of public parking at the harbour in an attempt to prevent queues developing at the harbour entrance which may impact on the Main Road through traffic. The VMS will be erected as follows:

1. at the harbour entrance,

2. on Clairvaux Road; and

3. on Main Road before the Kalk Bay Station parking area.

Kalk Bay Roadworks Update

August 17, 2012

Please be advised that Main Road will unfortunately not be opened to two-way traffic to Clairvaux Road by the end of this week as previously communicated.

The continuous inclement weather has delayed works to the extent that the Contract has not been able to complete the sewer manhole rehabilitation or the footway asphalt. Depending on the weather, the Contractor expects to complete these works and open Main Road to two-way traffic before the end of August 2012. The works are currently 3 weeks behind programme at this stage.

Section G And H (Programme and Implementation)

Once Main Road is opened to two traffic up to Clairvaux Road, work on Section G will commence. Before work can commence, temporary signals and control equipment for a stop-go system will be installed.

The existing traffic signals at the Clairvaux intersection and the harbour entrance will be de-activated and 3 sets of temporary stop/go signals installed together with a dedicated signal controller. This will be similar to the system installed under the Phase 1 contract. The Metrorail crossing will be managed manually, by trained personnel.

Each signal will operate on an approximate two to five minute cycle but will be adjusted as circumstances warrant. The three cycles will be set up as follows:

1. Clairvaux Road :

Left or right turning traffic into Main Road.

2. Main Road Southbound :

Right turning into Clairvaux Road or straight on to Clovelly.

3. Main Road Northbound :

Left turning into Clairvaux Road or straight on to Muizenberg.

In addition 3 variable messaging signs (VMS’s) will be erected to indicate the availability of public parking at the harbour. The purpose of these signs is to indicate, in advance, the availability of parking in an attempt to prevent gridlock at the harbour entrance. One VMS will be erected at the harbour entrance, another on Clairvaux Road and the third one on Main Road before the Kalk Bay Station parking area.

Section G Southbound involves the construction of a new sewer, stormwater reticulation and stormwater culvert crossing at Clairvaux intersection. It is expected that this section will take 10 weeks to complete depending on the quantity of rock encountered.

Section H northbound includes the construction of both the 700 and 300 water mains which will be laid in a common trench. This should reduce the overall construction time provided that the Contractor can handle the significant quantity of hard rock excavation that is expected. This section also includes the extension of the stormwater culvert and associated pipes and catchpits needed to drain the road and adjacent areas.

Work on the Clairvaux Road tie-in to main Road will be constructed on completion of Section H.

It was originally programmed to complete this section by December 2012 but because of the concentration of services and the hard rock, it is now envisaged that the work will extend into 2013. However, the project team will ensure that the stop-go system will not be in place during the December holiday shut down period and that Section H will be trafficable, albeit on a temporary surface.

Main Rd work schedule
