Quebec Autoroute 440 (Quebec City)
Autoroute 440 is a superhighway located in Quebec City. It includes two separate segments, respectively named Autoroute Charest and Autoroute Dufferin-Montmorency. Originally meant to be connected and form a single continuous highway via a tunnel under the city centre, these plans were shelved years ago and are not expected to be revived.
The designation of Autoroute Charest is derived from Boulevard Charest, which is the street continuation east of this segment of A-440.
Route description
The Autoroute Charest segment is long. It begins at the junction of A-73 and A-40 and ends at Saint-Sacrement Avenue. Originally built as a two-lane freeway in 1962, it was twinned in 1967.The roadway continues as Boulevard Charest into downtown Quebec, where A-440 traffic is directed along Rue Monseigneur-Gauvreau to reach the Autoroute Dufferin-Montmorency at its westernmost interchange.
The Autoroute Dufferin-Montmorency is long. It begins at Côte de la Potasse, one block north of Route 175, and ends at the junction with A-40 in Beauport. The portion from Route 175 to Boulevard Henri-Bourassa was built in 1976 and the rest of the segment was built in 1982.
The autoroute was designated Dufferin-Montmorency because it extends former Avenue Dufferin in Quebec City and ends near the Montmorency Falls in Beauport. Lord Dufferin was a Governor General of Canada and had significant ties to Quebec City.
