PLANNING AND DESIGN CONSIDERATIONS FOR THE DU TOITSKLOOF HIGHWAY TUNNEL

Planning for the Present du Toitskloof (Huguenot) project began as long ago as 1970. Owing to the energy crisis in 1973 and subsequent fuel supply problems for South Africa, there were insufficient funds available to proceed with construction of the project at the earliest opportunity. This paper describes the history of the planning as well as giving details on the various facets that had to be considered during the planning and design phases. Details of the design of the main tunnel, portal buildings, and main control centre are provided, including landscaping details at the main control centre and the layout of the western and eastern approach roads. Brief details of the initial feasibility studies are also provided as well as the proposals for the tunnel design and methods of excavation put forward by the consultants, and a summary of the contracts awarded to build the tunnel. The tunnel was completed and opened to traffic on 18 March 1988 by state President P W Botha, who also named it the Huguenot Tunnel. (TRRL)
