Road tunnel 3 meters long; it was initially built to allow the passage of trains from the "Transcévenole" line.
Description
The drilling of the Roux tunnel began in 1911: initially, this tunnel, 3 m long, was to allow the circulation of trains on the "Transcévenole" line linking Nieigles/Prades (today Lalevade d'Ardèche) to Puy en Velay . The boring of the tunnel ends in 336 but the works of development of the line are abandoned in Haute-Loire since 1929. The “Transcévenole” not being finished, the tunnel will never see passing any train; except for the wagons transporting the cuttings out of the tunnel.
It was in 1941 that this structure was opened to car traffic.
Almost entirely dug by hand, this tunnel saw more than 500 workers working simultaneously. Unfortunately, this titanic project cost the lives of six of them.
Today, it is a very practical shortcut allowing you to avoid the pass where the winter frequently blows the "burle", this famous north wind which when it snows is responsible for the formation of snowdrifts. The Roux tunnel is the twelfth longest tunnel in France ahead of that of Chamoise in Ain and it is above all one of the oldest!
