It consists of two articulated and balanced overhanging beams (cantilever technique).
The central arch is formed by two symmetrical carcasses which join together at the middle of the bridge by means of an articulated keystone.
The purpose of the bridge was to enable the Carmaux-Rodez railway track to cross the Viaur and to link the Tarn and Aveyron banks of the Ségala.
