The New Coastal Highway will be about 13km long. The Highlight of this connection of Saint Denis and La Grande Chaloupe is a 5400m viaduct along the coast cliff – a bridge over the water surface. It will carry 2×3 traffic lanes. Two of them will be reserved for light and public transport: Buses, pedestrians and bycicles.
The viaduct is needed because the existing cliff road suffers from rock-falls and floodings caused from tropical storms. It will keep a safe distance to the cliff.
The Viaduct cost about 715 million Euro. Most of the structure will be prefabricated on land and the installed by sea.
Two other packages icluding heavy earth movement and earth works cost about 530 million Euro. In this area TILOS will be used.
The project will be completed in 2018.
