The demolition of the St. Jacques St. Bridge over the Decarie Expressway is finally going to begin this weekend, four years after it was first announced and more than three years after it was supposed to take place.
For this weekend and next, every lane of the Decarie Expressway will be closed, along with multiple other ramps in the Turcot Interchange.
The closures will begin at 10 p.m. Friday and last until 5 a.m. Monday.
Highway 15 southbound
- Highway 15 southbound will be completely closed from the Sherbrooke / St-Jacques St. exit to the Turcot.
- The Royalmount, Jean-Talon, Cote-St-Luc and Girouard entrances to Highway 15 south will also be closed
- The Downtown Montreal / Champlain Bridge and Highway 40 West exit will be closed
Highway 15 northbound
- Highway 15 northbound will be completely closed between the Turcot and the Sherbrooke entrance, and all interchange ramps leading to Highway 15 north (from Highway 20 east, 720 east of 15 north).
Some entrances to Highway 15 will be closed to traffic as of 8:30 p.m. Friday.
Crews will be working around the clock to destroy the western half of the bridge and lower the debris to trucks that will haul it away.
If the work does not go as smoothly as anticipated the demolition will continue the weekend of July 23rd.
Then, in the fall, the eastern half of the bridge will be taken down, requiring several more weekends of closures.
Transport Quebec is asking drivers to avoid Highway 15 during these two weekends and instead follow the posted detours to Highway 13.
