The Nelson Mandela Bridge is a bridge in Johannesburg, South Africa. It was completed in 2003 with an R38 million price tag. The proposal for the bridge was to link up two main business areas of Braamfontein and Newtown as well as to rejuvenate and to a certain level modernize the inner city, which is an initiative by a company, Blue IQ. The bridge was constructed over 42 railway lines without disturbing railway traffic and is 284 metres long.
There are two pylons, North and South, and are 42 and 27 metres respectively. Engineers tried to keep the bridge as light as possible and used a structural steel with a concrete composite deck to keep weight down. Heavier banks along the bridge were reinforced by heavier back spans. The bridge consists of two lanes and has pedestrian walk-ways on either side. The bridge can be viewed from one of Johannesburg’s most popular roads, the M1 highway.
Of recent times it has been known the many copper wiring has been stolen from the bridge which has causes tighter security measures, including full 24-hour video surveillance of the bridge.
A bridge linking Braamfontein to the Johannesburg city centre was first mooted by Steve Thorne and Gordon Gibson, urban designers, in 1993 in their urban design study of the Inner City of Johannesburg. In their study they named the bridge the Nelson Mandela bridge in recognition of the role Nelson Mandela was having in uniting South African society, and the symbolism of linkage and unity provided by the bridge.
