The Beacon Bay-Gonubie Link Road is a dual carriageway road, planned to improve access to existing and future developments around the Buffalo City Metropolitan Municipality (BCMM) in East London.
Bosch Projects took over this project in 2017 upon acquisition of THM Engineers EL (THM), who were originally appointed by BCMM for the planning and design of the Link Road.
The project is a dual carriageway road comprising two 3.4m lanes separated by a 4.0m wide paved median. The Qinira River bridge crossing is a reinforced concrete dual span structure, determined more by geometric considerations than by hydraulics. The road classifies as Urban Arterial, with a design speed of 80km per hour that drops to 60km per hour only on the section west of the river, where access is restricted.
The road cross-section allows for intermodal transport, including pedestrian walkways and cycle paths on both sides of the road. Conflict of movements between motorists, pedestrians and cyclists is avoided in the design.
Key environmental considerations include:
- Cuttings and fill embankments will be planted for erosion control
- Innovative soil retaining systems to reduce the temporary scar caused by construction work
- Aesthetics of the bridge structure were chosen to minimise environmental impact at and surrounding the river bed.
Phase 2 now under construction and is as follows:
- 680m of asphalt dual carriageway
- A storm water management system including a reinforced concrete major culvert
- Pedestrian walkways, cycle paths and a traffic circle
- Street lighting by an electrical sub-contractor.
The construction value of Phase 2 is R70.7 million and completion is expected by December 2018.
