Garabit highway bridge, Concrete bridge in Ruynes-en-Margeride, France.

The Garabit highway bridge is a 311-metre concrete viaduct on the A75 at kilometre 104, near Ruynes-en-Margeride and Val d'Arcomie, crossing the Truyère. Its prestressed concrete box girder is fixed on two inclined legs, or béquilles, and simply supported on the abutments, with three spans of 82, 144 and 82 metres. The deck is 20.50 metres wide and varies in depth from 8 metres at the legs to 3 metres at mid-span.

The Garabit highway bridge was built by a group of companies, Dumez and GTM, and opened to traffic in June 1993. It was inaugurated on 2 July 1993 by President François Mitterrand. The structure carries the A75 motorway at kilometre point 104.

The bridge carries the A75 at kilometre point 104, and its name links it to the Garabit viaduct, the red steel arch visible from the deck. It was inaugurated on 2 July 1993 by François Mitterrand, the year the A75 section opened.

Drivers cross the bridge via the A75 motorway and enjoy wide views of the Truyère valley during their journey. The best views of the structure itself can be found from nearby viewpoints where you can see its full height and span clearly.

The structure is specially designed to withstand the strong winds of the Massif Central that are particularly powerful at this elevation. This stability resulted from careful planning and innovative engineering required to ensure safe passage across the valley.
