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.
