The Viaduct Maupré , officially the Viaduct Charolles is a road bridge north of Charolles in Saône-et-Loire in the French region of Bourgogne Franche-Comté . It leads the route Center-Europe-Atlantique , here Route nationale 79 , over the Maupré valley and the Routes départementales D 25 and D 985.
The 325 m long and 10.75 m wide bridge has two lanes and narrow hard shoulders. Its seven openings have pillars up to 23 m high and 40 to 53 m apart.
The deck girder has a constant height of 3 m. It consists of a continuous prestressed concrete slab, trapezoidal sheets arranged in a V-shape and, as the lower chord, a centrally arranged steel tube with a diameter of 60 cm. The deck slab is 20 cm thick and transversely prestressed. The tendons of the longitudinal prestressing are located within the V-profile, which is formed by the 8 mm thick trapezoidal sheets. The steel pipe was filled with concrete after assembly.
The viaduct was designed by Michel Duviard, planned by Jacques Combault and Pierre Thivans, and built by Campenon Bernard between 1984 and 1987 .
At that time, the French bridge engineers were looking for ways to reduce the weight of the beam girder and thus achieve lower construction costs. The Pont d'Arbois was one of the first smaller bridges where these ideas were implemented. Similar solutions were implemented with the Viaduc de Maupré and the Viaduc de Sylans .
