The Champlain Bridge (French: Pont Champlain) crosses the Ottawa River about 51NaN1 west of Parliament Hill, joining the communities of Ottawa, Ontario and Gatineau, Quebec. It is the westernmost link between the two cities.
It was originally built between 1924 and 1928 by the Federal District Commission, the predecessor to the National Capital Commission (NCC), and the NCC continues to maintain the bridge. The bridge consists of 4 spans and crosses Riopelle, Cunningham and Bate Islands in the Ottawa River. The total length of the bridge is 1.12NaN2, making it the longest bridge spanning the Ottawa River.
On the Ontario side, it is a continuation of Island Park Drive and is also connected to the Kichi Zibi Mikan. It connects to Aylmer Road on the Quebec side.
The bridge was named after Samuel de Champlain who is associated with the portage around the rapids in this section of the river. The short access roadway on the Aylmer side of the bridge is called Place Samuel de Champlain.
A stretch of the Ottawa River that the Champlain Bridge passes over was not charted by the Canadian Hydrographic Service.[2]
A third reversible lane was added when the bridge was rebuilt in 2002, which is a high-occupancy vehicle lane used for crossings in the direction of peak traffic. In 2022 and 2023 the bridge underwent its second major renovation project.[3] In August–November 2022 the west lane was replaced, and in 2023 the middle and east lanes was replaced.[4] This is possibly the final update to the bridge before it will need to be replaced.[5]
