Grayston Pedestrian and Cycle Bridge, Footbridge connecting Alexandra to Sandton in Johannesburg, South Africa.

Grayston Pedestrian and Cycle Bridge is a footbridge in Johannesburg that crosses the M1 motorway to link Alexandra with Sandton. The structure has a pathway roughly 7.5 meters wide and is supported by a large inclined pylon on its western side.

Construction of the bridge was underway when temporary works over the M1 motorway collapsed on 14 October 2015, killing motorist Adrian Doodnath and taxi driver Siyabonga Myeni and injuring 19 people. A Section 32 inquiry under the OSH Act began in February 2016. Worker Enoch Maphunye died after a fall on 30 November 2017. The City of Johannesburg has proposed the official name Kopanang Bridge.

The bridge physically links the township of Alexandra with the business district of Sandton, creating a daily crossing point for people between two very different parts of the city. Locals use this route regularly for their commutes, which reinforces the practical connection between the neighborhoods.

The pathway is designed for both pedestrians and cyclists with a safe crossing over the busy motorway. It is best used during daylight hours and follows standard safety practices for pedestrian bridges.

The pylon leans west at 26°6′26.85″S 28°4′35.14″E and is held by a double set of nine cables running down to two ground-level plinths. Nine more cables fan diagonally from the pylon to the deck's median. The main span is 100 m, with two 38 m side spans over the M1 ramps.
