Second Frejus Tunnel Opens

2nd August 2025

A new road tunnel under the Alps linking France and Italy has been officially opened to traffic.

It runs parallel to the original one and has been under construction for 10 years.

The 12.9km tunnel connects Modane in the Savoie, France, with Bardonecchia in Piedmont, Italy.

It forms one of the main trans-alpine freight and passenger routes between the north of Europe and the south.

The route is used by over two million vehicles each year, including one million heavy goods lorries.

It was officially opened by French Transport Minister Philippe Tabarot and his Italian counterpart Matteo Salvini.

“After the reopening of the Tende tunnel just one month ago, this is another strategic axis between France and Italy that is now strengthened,” said Philippe Tabarot.
