The Champlain Bridge opened to traffic on June 28, 1962 and was named in honour of explorer Samuel de Champlain, who founded Quebec City in 1608. The Bonaventure Expressway, which is part of the north approach to the bridge, was opened to traffic on April 21, 1967.
The Champlain Bridge links the boroughs of Brossard and Verdun, and is approximately 3,4 kilometres in length. It carries six lanes of traffic separated by a median. The main cantilever span is made of steel. It supports an orthotropic steel deck with a bituminous asphalt pavement. Clearance above the surface of the St. Lawrence Seaway is approximately 49 metres. The remainder of the bridge consists of prestressed concrete beams supporting a prestressed concrete deck covered with asphalt pavement.
The reserved bus lane on the Champlain Bridge is operated by the Agence métropolitaine de transport (AMT) Monday-Friday, 5:30 AM-9:30 AM and 3:00 PM-7:30 PM.
Approximately 59.4 million vehicles cross the Champlain Bridge every year.
