The Versoix Bridge is located near to the city of Versoix, crossing the river with the same name. It lies on the A1 highway between Lausanne and Geneva, Switzerland making an important connection between two major Swiss cities (60’000 vehicles per day). 1996 – 1998, the bridge was refurbished and enlarged to accommodate an additional security lane in both directions. Since an important amount of new concrete was added asymmetrically to an existing structure, the issues of differential shrinkage could occur and decrease the structural performance.
