Built in 1898, it carried the St. Johnsbury and Lamoille County Railroad across the Missisquoi River just west of Swanton village.

The bridge was listed on the National Register of Historic Places in 1973, and has not been delisted despite its destruction.

[1] The former St. Johnsbury and Lamoille Railroad right of way runs generally easterly from the north-south main line of the Central Vermont Railroad, which runs roughly parallel to the west bank of the north-flowing Missisquoi River west of Swanton village.

The covered bridge that stood at this site comprised three spans, with a total length of 369 feet (112 m), set on stone abutments and piers.

The bridge was a distinctive combination of Pratt and Town trusses, and had a massive interlaced wooden deck system.
