To begin with, the tunnel will be closed overnight between 10pm and 6pm.
This will be the case on Monday 18th September as well as the 3 nights afterwards.
The situation will then continue indefinitely Monday-Thursday until the tunnel closes fully for a 7 week period.
“The exact planning of this total closure is currently being finalised by the TMB-GIE technicians and the contractors in charge of the works. The exact dates of this closure will be communicated and published as soon as possible,” says the tunnel operator.
