Built in the 19th century, this bridge quickly became the main crossing point of the Real Collobrier as evidenced by the request for classification by the Municipal Council of February 25, 1877 "as a continuation of the road No. 14".
During the Liberation, a truck broke the rail and it is only in 1955 that it will be repaired and expanded. It is now called Roger ROSSI, hero of the resistance died on August 18, 1944 in the Vercors. A commemorative plaque pays tribute to him there.
