The ministère des Transports et de la Mobilité durable has once again changed the planned dates for the thaw period and the accompanying weight restrictions.
Here is the new updated load restriction periods, for each of the spring thaw zones :
- Zone 1: Monday, March 20 (12:01 a.m.) to Friday, May 19 (11:59 p.m.)
- Zone 2: Monday, March 20 (12:01 a.m.) to Friday, May 19 (11:59 p.m.)
- Zone 3: Monday, March 20 (12:01 a.m.) to Friday, May 19 (11:59 p.m.)
Dates are now the same for all three zones.
We will inform you if, due to weather conditions, other changes occur.
