Will Dawson’s parking lot be affected?

What renovation work is being undertaken?

The STM will completely replace the membrane that ensures the Atwater station is waterproof and will take advantage of the construction already planned to install two elevator shafts connecting the Metro mezzanine to the platforms.

Will the work be noisy?

The College has received assurances from the STM that its contractors will respect all laws and regulations regarding noise levels for both the City of Westmount and for Montréal for construction projects, and its engineers have promised to keep noise levels inside the Metro area where work is being done to established safe decibel levels between 80 and 106.

Why were the trees on De Maisonneuve Boulevard cut down?

The STM cut down trees and bushes on De Maisonneuve in preparation for the major construction work that will take place. At the end of the project, the STM will replant trees and bushes that are native to Quebec instead, increasing our campus biodiversity and providing additional food, shelter and nesting opportunities for local wildlife.

Emergency evacuation procedures will not be affected.

How will the closure affect those with reduced mobility?

Transport Adapté will be able to enter Dawson College through the 4011 de Maisonneuve Blvd. West parking lot for drop-offs. A ramp and electronically-opening door will be installed at the B2 entrance to the College (its location is indicated on the map above).
