Cedar Road – Fourways, South Africa

The upgrade of the Cedar Road forms part of the road network of Gautrans and acts as an interurban collector for the surrounding townships.

 

Overview

WSP | Parsons Brinckerhoff was appointed for upgrading and rehabilitation of Cedar Road D1027, from Valley Road to Runnymead Road (approximately 2.4km in length). It carries a mix of light and significant heavy vehicle traffic because it transports building materials from the northern outskirts of Johannesburg. There has been significant development in this area over the past 15 years, and it is anticipated this growth will continue.

Challenges

Our client needed to improve traffic capacity and pavement integrity on Cedar Road for the next 20 years.

Additional project objectives included promoting black-owned economic enterprises for construction of portions of the Works, and employment of local labour.

Our Approach / Services

The project involved the widening of Cedar road on both sides to a double carriageway. The widening of the road consists of new pavement layers. The existing carriageway reached the end of its design life and was rehabilitated in-situ to match the added widening. The stormwater was upgraded to be drained in concrete pipes and kerb inlets. There were new facilities constructed such as pedestrian walkways and street lighting.

Scope of services included:

  • Geotechnical investigation
  • Traffic signals specialist investigation
  • Civil engineering services: Roads and bridges
  • Electrical engineering services: Street lighting
  • Preliminary design
  • Detail design and approval
  • Tender documentation
  • Construction monitoring
  • Project close out and reporting

Outcomes

WSP | Parsons Brinckerhoff completed the project within budget and within the contracted period. With the upgrading of Cedar Road, mobility was increased thus providing road users a decrease in travel time. Furthermore, 206 trainees were awarded certificates for the rehabilitation project.
