After months of construction and even some unfortunate setbacks, Highway 40 is taking another self-care break to receive asphalt work this weekend. For commuters, this means diversion to service roads and more traffic over the next few days, starting Friday at 11:30 p.m..

The affected area of the 40 is the entire eastbound section of road between Côte-de-Liesse and des Laurentides interchanges, which will be closed until 8 a.m. Sunday morning. If weather conditions are unfavourable (which doesn’t seem to be the forecast as of Thursday, August 18), the construction work could be postponed, promising future frustration from drivers across the city.

This asphalt work could be related to mistakes made in 2021 when sections of the 40 were repaved with low-quality asphalt, which now needs to be repaired. The construction contractors were charged an $820,000 fee, payable to the Ministry of Transport, and their $2.9 million payment was postponed until the repair work is completed.
