A unique commitment to minimising the impact on the environment underpinned all work completed during the recent upgrade of the N2 between Tsitsikamma and Witelsbos. The 14 km section of this strategic and scenic National Road through South Africa's Garden Route was the final section to be upgraded to toll road standards. The scope of work included the widening of the road to accommodate emergency lanes, and flattening of the horizontal planes to increase visibility. This involved realignment of the road, removal of undulations to create a better geometric shape and upgrading the subsurface - all of which has resulted in a significantly improved driving surface.
