Construction of the Gautrain Rapid Rail Link near Johannesburg's Park Station will start on February 11, the Bombela Consortium said on Tuesday.
The building - along Smit Street - would result in road closure and diversions until at least October, it said.
Road users could find details on the website www.gautrain.co.za.
Four multi-storey buildings were recently demolished in Wolmarans Street to make way for a structure housing the link's platform. - Sapa
