You may run into some delays if you're planning on taking the Mercier Bridge out of town this weekend, as crews inspect lighting and signage.
One of the southbound lanes will be closed from 6 a.m. until noon Saturday, while the exit for westbound route 138 toward Chateauguay will be down from 6 a.m. to 10 a.m.
On Sunday, one of the southbound lanes will close once again from 6 a.m. to noon, while the ramp for the eastbound 132 will close from 6 a.m. to 10 a.m.
Meanwhile, the inbound lanes of the Jacques-Cartier Bridge will be closed at 10 p.m. on Sunday night until 4 a.m. on Monday, as crews are set to paint some new road markings.
And once again, the eastbound Ville-Marie will be closed all weekend. The ramps from the 15 south and 20 east will shut down at 11:30 p.m. Friday and reopen at 5 a.m. on Monday.
Crews will be building a road between the exit of the westbound tunnel and the westbound lanes which will be used by westbound drivers when the demolition of the elevated westbound part of the expressway begins.
