Here's a list of where to avoid:- Complete closure of the Highway 15 southbound ramp (Décarie) leading to the Champlain Bridge.
- Complete closure of the Highway 15 southbound ramp (Décarie) leading to Highway 20 westbound.
Instead of taking those ramps, the Quebec's transportation department encourages people to access Highway 720 westbound via Fort Street and then take the ramp leading to the Champlain Bridge or Highway 20.
- Complete closure of exist 64-A on Highway 15.
The closures will start at 11 p.m. on Friday and run until Monday at 5 a.m.
As well, due to the weekly firework show in Montreal, the Ville-Marie tunnel and Viger Street eastbound will be closed from 8:30 p.m. on Saturday to 11:59 p.m.
