Guerville Viaduct

Construction of a third motorway deck and its connections to the south of the two existing decks

France, 2016-2019  

General description

As part of a major motorway revival plan, on a particularly dense section of the A13 motorway, Bouygues Travaux Publics built a third deck for the Guerville viaduct to enable the two existing decks to be renovated by temporarily shifting traffic. Ultimately, this viaduct, consisting of a composite structure with a 3,000-tonne steel framework, will also help to ease traffic flow by creating an additional lane for journeys between Paris and Caen. It was a highly complex project, operating above or near active rail and road traffic lanes. 

The installation of the 360-metre-long deck thus required no fewer than three launching operations. To enhance the safety of the teams, several systems were put in place, such as a sliding tool to prefabricate all the reinforcement mesh sheets at the extremities of the viaduct.
