Bridge No. 1132, Route 80, spanning Hammonasset River, Madison, New Haven County, CT

Significance: Bridge No. 1132 is significant as an example of an open-spandrel concrete arch, a bridge design developed in the early 20th century that was well-suited for crossings that were unusually long or high, as in the case of the deep ravine through which the Hammonasset River runs at this point. The bridge is also important because it recalls the extensive program of construction undertaken by the Connecticut State Highway Department in the 1920s and 1930s.
