The Vialleton Bridge, built in 1692, had for a long time already been infiltrated with water, causing resurgences in the arches raised successively between the 17th and the 19th centuries. In addition, the passage of cars under the bridge caused a serious deterioration.
Entrusted to RL&A, the project management has recommended waterproofing works. Also the restoration of the arches of the bridge was carried out.
