It was finally Tuesday that the ordeal of road users on Highway 40 in west, near Lanoraie, will be attenuated.
On Monday, the transport authorities indicated that the highway, closed in the direction of Montreal due to the sagging of a Ponceau, could be partially reopened to traffic at the end of the day, but that will not be the case. We are now counting on Tuesday.
The teams are actively working to open a misinterpretation, that is to say one way by management. We hope for the end of the day, but most likely tomorrow during the day
said Martin Girard, Transport Québec spokesperson. For the moment, he cannot give more details on the time envisaged.
Since Saturday evening, motorists who have borrowed this section must make a detour of around 21 km by route 138, which is not suitable to accommodate the approximately 37,000 daily passages that the motorway network during the summer. The local network usually welcomes 3,200 daily.

Work is underway to create two deviations which will allow the reopening of the important road axis, with a track in each direction, the spokesperson for the spokesperson said earlier in the day MTMDLouis-André Bertrand, in an interview with First the info on RDI.
Motorists will nevertheless have to provide a slowdown in traffic as the sector approaches, and those who can take highway 20 in their trips between Quebec and Montreal are asked to do so.
A pumice in question
On Saturday, we learned that the section of Highway 40 in the west direction, between Route 158, in Berthierville, and Chemin de Joliette, in Lanoraie, was closed to traffic.
This decision was made due to the sagging of a pumice between the rank of the South Bayonne River and the Joliette Chemin, in Lanoraie. A hole in the road had formed there.

Erosion at the ends of a ponceau is common, says Bertrand, even if nothing suggested that such damage could occur. The said Ponceau was however under surveillance
said the spokesperson.
The repair of the Ponceau should take approximately two weeks, indicates the spokesperson for MTMD.
The sagging of a pumice on the A40 West, between Berthierville and Lanoraie, notably created a hole in the roadway.
