The Bedell Bridge was a Burr truss covered bridge that spanned the Connecticut River between Newbury, Vermont and Haverhill, New Hampshire. Until its most recent destruction in 1979, it was, with a total length of 382 feet (116 m), the second-longest covered bridge in the United States. The bridge was divided into two spans of roughly equal length, and rested on a central pier and shore abutments constructed from mortared rough stone. The eastern abutment has been shored up by the addition of a concrete footing. The bridge was 23 feet (7.0 m) wide, with a roadway width of 18.5 feet (5.6 m). Because the state line is the western low-water mark of the Connecticut River, most of the bridge was in New Hampshire; only the western abutment is in Vermont.

The roadbed is 20'7" wide, with a vertical clearance of 14'7". The bridge is approximately 25' above the river. The western (Vermont) abutment is made of split granite quarried from nearby Fairlee Mountain, while the eastern abutment is an early concrete construction built in 1908 by John Storrs for an earlier bridge. The bridge underwent a major renovation in 1993 which included the addition of a sidewalk and replacement of much of the bridge decking.
The Samuel Morey Memorial Bridge is a historic bridge carrying New Hampshire Route 25A across the Connecticut River between Orford, New Hampshire and Fairlee, Vermont. The steel through-arch bridge was built in 1937–38 to replace an older wooden bridge which had been damaged by flooding in 1936. It spans 432 feet (132 m), stands about 35 feet (11 m) above the river, and its arches rise 85 feet (26 m) above the roadway. It rests on poured concrete abutments that have a light Art Deco or Moderne styling. Wing walls recede from the abutments into the banks in three stepped sections. Below the bridge in the river is visible some riprap, stone remnants of the old bridge's abutments and central pier. The bridge is of a "tied arch" design, in which the two arches are joined together by ties to distribute the active load. This is in contrast to the Justice Harlan Fiske Stone Bridge joining Brattleboro, Vermont and Chesterfield, New Hampshire, which was built about the same time, and distributes the active load to its abutments. The bridge components were manufactured by the American Bridge Company; construction was by Hagen-Thibodeau Construction Company at a contracted cost of just over $209,000.
