T he Houghton Heritage Wall Pedestrian Bridge forms part of the Johannesburg Development Agency’s Bus Rapid Transport System project connecting Sandton and the Johannesburg CBD. The project is multi-phase and the majority of the construction has already been completed. Section 15J is the penultimate phase of the project and includes the construction of BRT lanes along Louis Botha Avenue and the construction of a pedestrian walkway structure at Houghton Drive.

The length of roadway between Fife and Lily Roads was too narrow to accommodate the widening required for the BRT lanes and an existing stone retaining wall of historical and heritage significance formed the northern roadside boundary. These challenges led to the proposal to construct a pedestrian bridge adjacent to the heritage wall to provide a safe walkway and cycleway for the many pedestrians along Louis Botha Avenue. An innovative and original design was developed that met the client’s requirements, maintained the heritage and historical significance of the area, and was achieved within budget. z
