The hangers are made by cables 20 mm diameter) connected to the deck by fixed clevises at the bow and adjustable clevises at the apron. The deck is completed by pouring concrete on ribbed sheet metal 12cm high with longitudinal garbage.
The main geometric characteristics are as follows
• Range: approximately 72 m
• Height of the arch: approximately 15 m
• Useful width: 3.5 m

The Bonneville motorway viaduct consists of a girder deck in a composite system, simply supported over a span of 44 m. The 8 beams that compose it are coupled two by two, by means of I-section crosspieces 700 mm high.

The insertion of the structure in a zone strongly constrained by the interfering roads, imposed severe limitations on the heights of the beams ( Hmax = 1.1 m) , an aspect that led to thick flanges (maximum thickness 80 mm) and consequently required the imposition of important cambers (300 mm for the external beam on the “Macon” side).
