Major obstruction – Closure of A40 West for a few weekends in September and October

Project progress
Published on

As part of the REM work on the West Island, a segment of Highway 40 West will be completely closed from Friday, September 18 (10 p.m.) to Monday, September 21 (5 a.m.) and on other weekends in September and October. Plan ahead: avoid the area, and take Highway 20 if possible.

These closures are needed for the construction of a gantry for the REM elevated structure. A gantry, a portion of the elevated structure supported by two pillars, will be installed to help support loads while leaving a clear space for vehicle traffic. 

As part of this undertaking, the A40 West will be completely closed on the following weekends:

  • Friday, September 18 from 10:00 p.m. to Monday, September 21 at 5:00 a.m. 
  • Friday, September 25 from 10:00 p.m. to Monday, September 28 at 5:00 a.m.
  • Friday, October 16 from 10:00 p.m. to Monday, October 19 at 5:00 a.m.
  • Saturday, October 24 from 5:00 a.m. to Sunday, October 25 at 10:00 p.m.

On these weekends, although a detour will be possible via the A40 West service road, we recommend that users avoid the area and take Highway 20 instead.  
Here is a map showing the area concerned and the detour to be taken during closure.
