Traffic disruptions in the Fréjus Tunnel – schedule of closures and alternating traffic

Drivers travelling through the Fréjus Tunnel must prepare for temporary traffic disruptions. Owing to maintenance work, which started on February 3 and will continue until March 3, the organisation of traffic has been changed.

The greatest disruption will occur on 26 February (Wednesday) when the tunnel will be completely closed from 00:00 to 05:00. During this time, drivers will have to use alternative routes.

Alternating traffic at night

From Monday to Friday alternating traffic along the entire length of the tunnel may cause additional delays. Since no work will be carried out on Saturday and Sunday evenings, traffic disruptions are not expected during these times.
