Blakeslee and Sons for the Connecticut Highway Department and consists of six open-spandrel arches spanning 674 feet (205 m), and is a fairly large example of concrete open-spandrel construction.

[2] The bridge was reconstructed in 1994 and was listed on the National Register of Historic Places in 2004.

The five smaller spans (two on the west bank, three on the east) are each 76 feet (23 m) in length.

In addition to the arched portion of the structure, there are three concrete girder approach spans on each side, giving the bridge a total length of 859 feet (262 m).

After the state replaced the bridge, the industrial and commercial center of the Village of Cornwall Bridge slowly moved up the hill away from the river, to the current intersection of US Route 7 and Connecticut Route 4.
