Road traffic: a day of crossover classified red in Auvergne-Rhône-Alpes. “On Saturday all day, particularly intense traffic difficulties are expected on the routes serving winter sports resorts,” warned Bison Futé.
The weekend is marked by a peak in holiday departures and returns which affect the three zones. In the direction of departures, towards the mountain ranges the traffic will be "very dense". The A43 between Lyon and Chambéry accumulated more than 40 kilometers of traffic jams towards the Alps.
