The City of Cape Town has reached the halfway mark with its multi-million rand rehabilitation of Main Road.

The third and final phase of the Main Road rehabilitation project will be concluded in the latter part of 2017, with the investment in the new road surface, retaining wall at Clovelly, and underground services amounting to approximately R304 million.

The new road surface covers a distance of approximately 4.5 km from the intersection with Atlantic Road in Muizenberg to the intersection with Clovelly Road just past Kalk Bay.

The work coincides with the installation of new underground sewer pipes, water mains, stormwater pipes, and low-voltage cables, as well as street lights.

“We are currently building a new retaining wall above the railway line, partly to serve as a support structure for Main Road above and otherwise to make it possible for us to widen Main Road to such an extent that motorists can parallel park along the seaside and to provide for pedestrian footways on both the mountain and sea sides,” says Brett Herron, the City’s Mayoral Committee Member: Transport for Cape Town.

State-of-the-art technology

State-of-the-art technology in the form of a chemical solution is used on site to stabilise and compact the soil to ensure that it has sufficient bearing capacity for the foundations of the retaining wall.

This technology has enabled the City to save up to six months’ time with the project, which is significant for residents and business owners in the area, given the disruptions caused by the ongoing roadworks.

“Once finished, the retaining wall will extend for a distance of nearly 500m from Woolley’s tidal pool to Clovelly. It will stand over 6m tall in some places, buttressed to create shadow lines and with stone-cladding to make the wall more appealing and to improve the aesthetics.

“At this stage it is anticipated that the retaining structure will be finished by the end of 2015,” says Councillor Herron.

All timeworn underground services such as the 100-year-old sewer pipes and the like are being replaced along Main Road and behind the new retaining wall.

The 50-year-old existing water main is also being replaced with a 700 mm ductile iron pipe. This main will be connected to the new pump station at Clovelly, securing the water supply to residents in the far south for the next 30 to 40 years.
