Bridge No. 1132 is an open-spandrel concrete arch bridge carrying the two-lane Connecticut Route 80 across the Hammonasset River, between Killingworth and Madison, Connecticut. Built in 1934, it is one of a small number of open-spandrel concrete bridges in the state, and was noted for its aesthetics at the time of its construction. It was listed on the National Register of Historic Places in 2004.[1]
Description and history
Bridge No. 1132 is located in western Killingworth and eastern Madison, spanning the Hammonasset River south of Lake Hammonasset. The bridge spans a steep wooded ravine, with its main arch spanning Шаблон:Convert. There are three concrete girder spans on each side of the main arch, giving the structure an overall length of Шаблон:Convert. The road deck is Шаблон:Convert wide, but the arches supporting it are only Шаблон:Convert apart, with concrete ribs projecting to the sides of the arches for additional support. There are eight supporting concrete beams rising in each spandrel area of the arches.[2]
The bridge was designed by the Connecticut Highway Department and built by the Osborn-Barnes Construction Company of Danbury, Connecticut, in 1934. It was highlighted by the Highway Department for its scenic location. The state typically only built open-spandrel bridges for particularly long spans, or sites such as this one with steep sides. This bridge replaced an older one that had been located further down the ravine; its construction thus eliminated steep approaches on what is a major east-west roadway.[2]
