Motorists are advised that Malandela Road in KwaMashu will be closed to traffic before the M25 (Curnick Ndlovu) Highway on Saturday from noon to 6pm and on Sunday from 7am to 6pm.
Traffic will be diverted along the R102 and Queen Nandi Drive.
The closure is to allow the placing of precast concrete beams for the railway bridge being constructed across Malandela Road.
There are also planned roadworks on Magwaza Maphalala Road (Gale Street) which involves the milling out and replacing of the existing asphalt surfacing layer.
The section of Magwaza Maphalala Road affected by the planned roadworks stretches from Eaton Road to Che Guevara (Moore) Road.
Access will be limited during construction with at least one lane open at all times.
The daytime working times are 8.30am to 4.30pm. Roadworks are expected to start on Monday with completion anticipated by the end of July, weather and availability of bitumen permitting.
