Tender Package 1 which forms part of the Gauteng Freeway Improvement Project (GFIP) was designed and supervised by SNA/ITS Joint Venture and constructed by Siyavaya Highway Construction Joint Venture. Package 1 consists of Work Package A1 (17.8km) and Work Package A2 (1.1km) for the upgrading of National Route N1, Section 20 from the Golden Highway in the South to 14th Avenue in the North and National Route 12, Section 18 form Diepkloof to Uncle Charlie’s Interchanges respectively.
Tender Package 1 forms part of the Western Bypass of Johannesburg and the upgrading of this section has increased the basic number of lanes from 4 to 8 and also on certain sections from 6 to 8 lanes. These additional lanes on the Freeway have dramatically improved the capacity of this important transportation link for road users.
Also included in this package are 8 interchanges which have been upgraded or geometrically improved by the provision of additional lanes on the cross-roads which have significantly improved traffic flow across the Western Bypass as well as access of traffic onto the National Route.
Lighting has been provided over the full extent of the Freeway in the median as well as at interchange areas and under bridge overpasses which has greatly improve the operational characteristics at night.
