From WRS this morning.
The Mont-Blanc Tunnel will be closed for three months from September.
It’s to allow for major renovation work which had to be postponed from last year after a landslide blocked part of the A43 autoroute. The tunnel was kept open to keep the traffic flowing.
Authorities say the work is necessary to ensure safety in the tunnel, which is now 60 years old.
It will close on September 2nd and reopen December 16th.
A reminder from WRS this morning.
The Mont-Blanc Tunnel will be closed from 5pm on Monday for more than three months to allow for major renovation work.
The work had to be put off due to the closure of the Gotthard Base Tunnel following a derailment and then a landslide on the A43 autoroute – an important link between France and Italy.
The Base Tunnel will reopen on Monday after more than a year of repairs.
Alternative routes during the Mont-Blanc Tunnel’s closure are being suggested. Trucks should use the Fréjus tunnel, cars can take mountain passes.
Again!
The Mont Blanc Tunnel will be completely closed to traffic from September 1st to December 12th.
Officials say the shutdown is unavoidable, as detection systems, fans and other equipment must be dismantled, making traffic impossible.
The closure was agreed by French and Italian authorities for safety reasons.
During the 15-week period, heavy goods vehicles will be diverted to the Fréjus Tunnel, while cars will need to use alternative Alpine routes such as the Grand St. Bernard Pass.
PS I changed the thread title with 2025 dates.
And despite what is written above the Grand St. Bernard tunnel is likely a better choice than the pass.
