Severe traffic congestion is to be expected in the autoroute 15 area. The Ministère recommends that road users plan their trips and favour carpooling and public transit when possible. Several measures to promote public transit have been implemented since 2011 to reduce the impacts of the Turcot project construction work on traffic.

For easier travel on the network, use public transportation. Consult the Mobility Montréal section of Québec 511 to find travelling solutions that fit you.

The Ministère asks motorists to be vigilant and pay special attention to the orange signs. In order to find your new route, consult the My Route section.

Turcot interchange is a hub for road traffic in Montréal area interconnecting highways 15, 20 and 720 in addition of facilitating access to the Champlain Bridge. It is also an essential road link between Montreal-Pierre-Elliott Trudeau international airport and downtown Montréal.

After almost 50 years of service, the Turcot interchange, one of the most important interchange in Québec which has a traffic volume of more than 300 000 vehicles per day, must be rebuilt. Turcot Project also includes the reconstruction of Angrignon, De La Vérendrye and Montréal-Ouest interchanges, and adjacent sections of highways 15, 20 and 720.

This section includes all documents produced in English as part of Turcot Project, as notices to residents distributed door to door, advertisement and some presentations, notably those of NDG-Westmount Neighbourhood Committee.
