Title: Edmundston–Madawaska Bridge
Content:  The Edmundston–Madawaska Bridge is an international bridge which connects the cities of Edmundston, New Brunswick, in Canada and Madawaska, Maine, in the United States, across the Saint John River. The bridge consists of four steel through truss spans, each 70.71 m in length, for a total length of 287.12 m, which carries a two lane open steel grid deck roadway. The bridge was constructed in 1920, replacing a cable ferry, and opened in 1921. Its original asphalt and timber deck was replaced with the current steel grid deck in 1961. Transport Canada estimated the bridge's traffic at 759,803 vehicles annually in 2006. Effective October 27, 2017, the Edmundston-Madawaska Bridge weight restriction was reduced to 5 tons.

The 12.9 km Confederation Bridge, which connects Prince Edward Island and New Brunswick, is significantly shorter than the Newfoundland–Labrador link would be, and crosses the Abegweit Passage, a shallower and calmer body of water than the Strait of Belle Isle. In the lead-up to the October 2003 provincial election, Progressive Conservative leader Danny Williams promised to fund a feasibility study to placate link supporters. In 2016, Premier Dwight Ball launched a new pre-feasibility study to determine the costs of a tunnel link between the island and Labrador. In their 2019 election platform, the Liberal Party of Canada indicated support for a National Infrastructure Fund, including the Newfoundland-Labrador fixed transportation link, likely linking Yankee Point, Newfoundland with Point Amour on the (Labrador) mainland.
