Weekend traffic May 2-5, 2025: La Fontaine Tunnel closed again
La Fontaine Tunnel
The tunnel will be completely closed toward Montreal from 11 p.m. Friday to 5 a.m. Monday, as Montreal-bound lanes are reconfigured to use the new renovated tunnel as of Monday. The Boucherville-bound lanes were moved into that tunnel last weekend.
The tunnel toward the South Shore will be closed overnights — 11 p.m. Friday to 8 a.m. Saturday, and 11 p.m. Saturday to 9 a.m. Sunday. Souligny Ave. eastbound over the highway will also be closed during these times.
The new tunnel has a permanent vehicle height limit of 4.3 metres, down from 4.4 metres.
Île Charron will be accessible from the highway in both directions as of Monday, but travelling toward Montreal from the island will require a detour via the South Shore.
Mercier Bridge
The ramps to and from the bridge in Kahnawake will be closed overnight on the following schedule:
Route 138 east toward the bridge: 10 p.m. Friday to 5 a.m. Saturday.
The bridge toward Route 138 west: 10 p.m. Saturday to 5 a.m. Sunday.
Ramps to and from the La Prairie (Route 132) side: 10 p.m. Sunday to 5 a.m. Monday.
Detours will involve going to the other side of the bridge and making a U-turn.
