Grande Designs: A New Bridge for Reunion Island in the Indian Ocean is Intended to Sit Lightly on the Island's Fragile Environment
Unique environmental concerns and topography were only two challenges in designing a major roadway on Reunion Island in the southwestern Indian Ocean. The route, connecting the towns of Etang Sale and Saint Paul, required 20 nonstandard and 20 standard structures, a 300 m-long twin tube tunnel, two cut and cover tunnels, and four exceptional bridges. The authors discuss one of the exceptional bridges, a steel structure spanning the Grande Ravine, in detail. Design requirements included the ability to blend into the site without disturbing flora and fauna. Challenges included ravine size-a ground level width of 320 m and a depth of 170 m-as well as the need to protect of the nesting grounds of the Baillon's Puffins.
