Subwaybridge at Toulouse Crossing of the motorway ring by the A line of the light subway.
The 251 m long viaduct has 8 spans. The main one, 81 m long, is supported by two triple arches.
The arches are extended under the deck to bear on concrete inclined piles. Transversal steel rods supported by the concrete piles are used to transfer the horizontal loads to the deck.
The deck is composed of a concrete plate and two steel trapezoid bow-girders.
