MONTREAL -- It’s been a few weeks since roadwork has closed Montreal’s major arteries on the weekend. Last week, planned closures were scrapped – again – because of poor weather conditions. But this weekend, the forecast seems clear, so drivers can expect a complete closure of Highway 40.

The closures are due to the dismantling of a Highway 13 overpass.

"It's very complex work because the whole structure they need to dismantle is located between two new structures so they have to protect the new structure," said Transport Quebec spokesperson Martin Girard. 

The work is part of a $58 million project to rebuild the Highway 13 South overpass and its access ramps to and from Highway 40. 

Girard warned that drivers can expect further highway closures in the Montreal area as work continues. 

Barring a major weather change – as of Thursday evening, Environment Canada predicted sun and temperatures slightly below zero – the closures will go ahead.

Highway 13/40 interchange

Starting Friday at 11 p.m. and ending Monday at 5 a.m., the Highway 40, and its parallel service road will be completely closed in both directions at the interchange with the Highway 13.

As a result of the same closure, the Highway 13 South will also be closed between exit 6 and the entrance to the Highway 40 East.

The exit from the Highway 13 North to the Highway 40 West, and the parallel service road, will also be closed.
