Being a main throughway linking the Lanseria area with Fourways, passing Steyn City, Dainfern, Chartwell, Broadacres and Lonehill, Cedar Road experienced heavy congestion, especially during peak times. Upgrading and rehabilitating the road was crucial – and proved instrumental in bettering the daily lives of motorists.

Design challenges

Traffic volume along Cedar Road had increased significantly over the last few years, with peak hour traffic nearing 2 000 vehicles.

“Our initial investigations found that Cedar Road was not in a great state, particularly from a pavement structure perspective. We also identified that capacity improvements were needed,” explains Francois van Rensburg, from WSP’s Bryanston office.

Additionally, the intersection of Cedar Road and Frederick experienced considerable storm water problems, which also needed to be addressed.

WSP worked hand in hand with Steyn City and the Gauteng Province Department of Roads and Transport (GAUTRANS) to rehabilitate and upgrade Cedar Road. To aid congestion, the road was widened on both sides to a double carriageway, including new pavement layers.

The storm water drainage was upgraded to concrete pipes and kerb inlets to help solve the problems at the intersection of Frederick and Cedar Road. At various intersections, additional turning lanes were constructed, with traffic signals upgraded at the Lombardy intersection. And, finally, to improve traffic and pedestrian safety, new facilities such as pedestrian walkways and street lighting, in collaboration with City Power, were also installed along the route.

Investing in local labour and construction companies

One of the project objectives was to promote local labour and SME enterprises. According to the Construction Contract, 30% of all labour on the project had to be sourced locally, and 40% of the contract value must be spent through utilising qualified SMEs, B-BBEE contractors and women-owned suppliers and sub-contractors. This proved invaluable, contributing to the betterment of economic sustainability in the area.
