Dorval interchange

The Dorval Interchange – consisting of the Dorval traffic circle and the interchange for Highways 20 and 520 – suffers from traffic congestion and poor accessibility. Located near several main thoroughfares, including Highways 13, 20, 40 and 520, as well as Montréal–Pierre Elliott Trudeau International Airport – one of the metropolitan area’s largest generators of vehicle traffic – the interchange plays a major role in Québec’s strategic road network for the transportation of both goods and people.

This area is an important intermodal hub, where train, automobile, bus and truck routes intersect and where thru traffic and local traffic merges with that moving to and from the airport. The situation has repercussions on local, regional and national economic activity.

To improve this situation, Transports Québec is working together with the City of Montréal, the borough of Dorval–l’Île-Dorval and Aéroports de Montréal. The project to improve ground transportation infrastructures near Montréal–Trudeau is intended to facilitate airport access, ease traffic congestion in the interchange and improve connections with public transit. Work is scheduled to begin in 2007 and end in 2011.
