Built in the 19th century, this bridge quickly became the main crossing point for the Réal Collobrier, as shown by the request for classification by the Municipal Council on 25 February 1877 "as a continuation of road N°14".
During the Liberation, a lorry broke the railing and it was only in 1955 that it was repaired and widened.
Today it bears the name of Roger ROSSI, a Resistance hero who died on 18 August 1944 in the Vercors.
A commemorative plaque pays tribute to him.
