A major roadwork blitz this weekend is expected to turn Highway 40 and other Quebec roadways into a nightmare for drivers.

The westbound highway will be closed between St-Charles Boulevard in Kirkland and Anciens-Combattants Boulevard in Ste-Anne-de-Bellevue from Friday at 10 p.m. until Saturday at 10 a.m. and then again from Saturday at 9 p.m. to Sunday at 9 a.m.

Transports Québec said drivers will be detoured via St-Charles Boulevard to Highway 20.

The eastbound Hwy 40 will also be closed in the same area on Saturday from 9 p.m. until Sunday at 9 a.m. Transports Québec spokesman Mario St-Pierre said drivers will be able to take the eastbound service road.

Those closures are just some among many expected for this weekend. Lane reductions and closures are listed for Rigaud, Vaudreuil-Dorion and other roads near the Quebec-Ontario border.

The Jacques-Cartier Bridge will also be closed Saturday from 8:30 p.m. to midnight for the fireworks competition at La Ronde.
