Missisquoi River Bridge, Steel truss bridge at Canada-United States border, Vermont.
The Missisquoi River Bridge is a steel truss structure at the US-Canada border connecting Richford, Vermont to Sutton, Quebec. The construction spans the river with two distinct sections and features a concrete deck designed to accommodate cross-border traffic.
The bridge was built by the state of Vermont in 1929, part of a programme that erected more than 1,200 bridges after the floods of 1927. It was manufactured by the Pittsburgh-Des Moines Steel Company, one of only two known Vermont bridges by that firm, and follows the state's standardised design of the period. It was listed on the National Register of Historic Places in 1990 and closed for rehabilitation from early 2018 until 7 October 2019.
The bridge connects two communities with names rooted in indigenous language, with Missisquoi coming from an Abenaki word meaning 'where there is flint'. This naming heritage remains part of the region's identity today.
The bridge provides two traffic lanes with adequate space and a clearance height that accommodates standard vehicles. Visitors should note this is an active border crossing where normal inspection procedures apply.
The bridge is one of only two in Vermont built by the Pittsburgh-Des Moines Steel Company, and one of three surviving Parker truss metal bridges in Quebec. Its riveted spans rest on poured-concrete abutments and a central pier, and it kept its original configuration through the 2018–2019 rehabilitation.
