oa Civil Engineer in South Africa - Planning and design considerations for the Du Toitskloof Highway Tunnel
Planning for the present Du Toitskloof project began as long ago as 1970. Owing to the energy crisis in 1973 and subsequent fuel supply problems for South Africa, then, 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. 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.
