Transport Quebec says Montreal drivers can expect more overnight road closures on Highway 25 over the weekend.
Highway 25, including the Louis-Hippolyte-La Fontaine tunnel, will be closed to allow for concrete operations to take place near the Souligny Avenue area.
Between 11 p.m. on July 11 and 8 a.m. on July 12, Highway 25 toward Montreal — between exit 90 — Highway 20 West, Route 132, La Prairie / USA, Varennes, P.-E.-Trudeau airport — and the entrance from Hochelaga Street, will be fully closed.
This closure will also take place between 11 p.m. on July 12 and 9 a.m. on July 13.
During the same time frames, Highway 25 toward the South Shore between exit 5 — R-138, Hochelaga Street, Sherbrooke Street — and the entrance from Île Charron will also be closed.
