Edmundston–Madawaska Bridge, International road bridge between Edmundston, New Brunswick, Canada and Madawaska, Maine, United States

The Edmundston-Madawaska Bridge is a four-span steel truss structure that stretches roughly 287 meters across the Saint John River. The construction carries road traffic between two countries on a two-lane roadway.

The first bridge on this site opened in 1921, replacing a hand-pulled ferry that had carried people across the Saint John River. Its original asphalt and timber deck was replaced by the current steel grid deck in 1961. A replacement bridge costing $135 million opened in June 2024, and the old span is slated for demolition.

The crossing is the Madawaska–Edmundston Border Crossing, where the US inspection station stands at the Maine end. The first US border post there was a small white cabin at the bridge exit; a two-storey wooden station followed around 1930, replaced by the present one-storey brick building in 1960. Canada's small wooden station with a red roof was replaced by a brick facility in 1992.

Crossing is straightforward since the bridge is part of regular traffic flow and used daily. Visitors should be aware that ongoing or planned construction may affect travel conditions.

The original 1921 crossing had an asphalt and timber deck; the open steel grid roadway seen today dates from a 1961 replacement. The bridge carried an estimated 759,803 vehicles in 2006, and since October 2017 it has been limited to 5 tons, with heavier vehicles rerouted to Fort Kent–Clair or Saint Leonard–Van Buren.
