Bridge strengthening in Courrendlin JU
02. May 2021
A stone arch bridge was widened on one side between 1950 and 1970 by a reinforced concrete construction consisting of 2 girders and 1 parapet. The girders rest on abutments and are connected by struts and a concrete slab. At the bottom girder surface, the concrete is carbonated and the internal reinforcement partially corroded.
