What is the proposed project?

Public Services and Procurement Canada is proposing to replace the Quebec Timiskaming dam-bridge. The dam-bridge spans the Ottawa River, connecting the provinces of Ontario, 65 kilometres northeast of North Bay, and Quebec, at Temiscaming. The new structure would include a two-lane roadway and a sidewalk and would regulate water levels on the river. It would be approximately 75 metres long, and have ten bays with vertical sluice gates. The construction of the new dam-bridge would take place over 30 months.
