The viaduct is 1,600 feet (490 m) long structure, consisting of masonry arches and earthen embankments in the Massachusetts portion of the village of Waterford.

The most prominent portion of the structure is an 800-foot earthen embankment running west from the river that is 25 feet (7.6 m) high, and then a 375-foot (114 m) multiple-arch masonry bridge constructed out of granite which was sheathed in concrete in 1918.

That company completed the connection between Blackstone and New Haven, Connecticut in 1873, part of which included construction of this viaduct, replacing an older wooden trestle.

[2] In the late 1960s, floodwaters washed away an abutment of the adjoining trestle to the east, ending service over the viaduct.

[2] The Massachusetts Department of Conservation and Recreation (DCR) purchased a section of the right-of-way, including the viaduct, in the 1980s for possible conversion to a rail trail.
