This paper gives a resumé of the National Commission's involvement in the planning, design and construction of a section of national road N2 in the Tsitsikamma. More specifically attention is devoted to the alternative routes investigated and in particular the topographical, geological and ecological problems encountered in crossing the Bobbejaans River, Groot River and Bloukrans River flowing in very deep gorges. Design criteria is given and the tender procedure adopted is discussed. A description of the philosophy followed by the Department of Transport to ensure sound site relations is given together with a summary of the final costs and some comparative cost factors.
