The Proposed Project

Public Services and Procurement Canada is proposing to replace the Quebec Timiskaming dam-bridge located 65 kilometres northeast of North Bay, Ontario, and bordered by the city of Temiscaming, Quebec, to the east. As proposed, the project will result in the replacement of the Quebec Timiskaming dam-bridge, a structure that regulates water without generating electrical power. Its deck supports a two-lane roadway connecting the provinces of Quebec and Ontario. This complex includes two independent dams located on both sides of Long Sault Island on the Ottawa River: the Quebec dam-bridge and the Ontario dam-bridge, which was replaced in 2014. The new structure will be approximately 75 meters long and will have 10 bays: five with vertical sluice gates and five working with wooden beam weirs. The road deck will consist of two traffic lanes as well as a sidewalk. The construction of the new dam-bridge will be spread over a period of 30 months.
