Long-Sault Bridge, Interprovincial bridge between Hawkesbury, Ontario and Grenville, Quebec, Canada.
Long-Sault Bridge crosses the Ottawa River for about 650 meters, linking eastern Ontario to western Quebec with a concrete and steel structure. The design incorporates Chenail Island as a natural support point within the crossing.
An earlier crossing, the Perley Bridge built in 1931, served this route for over six decades before being replaced. This current bridge opened in 1998, providing a modern fixed crossing for the region.
The crossing links two provincial communities separated by the river, serving as a daily meeting point between Hawkesbury and Grenville. People from both sides use this route to visit family, work, and access services on either province.
This is the main vehicle crossing between the two provinces, so it can be busy during rush hours and weekends. The road stays open year-round, though winter weather can affect driving conditions.
The bridge's design deliberately uses Chenail Island as an integral part of its structure, rather than simply spanning over it. This engineering approach creates a more efficient foundation and is noticed by few who cross it.
