Thaw period - official dates

​The Ministère reminds users of heavy vehicles and shippers that the authorized load limits are reduced during the thaw period on all public roads. This is done every year to account for the road network’s lower bearing capacity during this period.

For the thaw period of 2019, the official dates of the load restriction period for each of the thaw zones are indicated below.
