Director: Dewar van Antwerpen

With over a thousand pedestrians from the township of Orange Farm crossing the N1-19 daily, the South African National Roads Agency Limited (Sanral) decided to put up a pedestrian bridge across the busy highway.

It is a steel structured bridge, which is slightly curved and includes a triangular shaped beam made up of structural steel hollow sections. The curve frame has a large top central circular element. The V-pattern side bars are tapered from top to bottom, while the bottom chords consist of two circular elements that are spaced approximately 3,8 metres apart.

Centred in this width, two channels have been placed at 2,5 metres for the walkway. The deck consists of a 100mm thick slab. The bridge is enclosed using a galvanised steel mesh with a height of 2,4 metres on the sides.
