West Cornwall Covered Bridge
}}
The West Cornwall Covered Bridge (an earlier incarnation was known as the Hart Bridge) is a wooden covered lattice truss bridge carrying the Sharon-Goshen Turnpike over the Housatonic River in the town of Cornwall, Connecticut. Records indicate that a bridge may have been in place in this location as early as 1762. A previous bridge was destroyed in the flood of 1837 and a new bridge was constructed in 1841. This bridge would also be destroyed and the current bridge would be completed circa 1864. Utilizing the central pier from the previous incarnation, despite the Town lattice being able to withstand the weight and single span, the bridge has two spans. The later addition of queen trusses and supports gives the bridge an unusual appearance. Modernization of the bridge in 1968 and 1973 has continued to let the bridge handle traffic. It was added to the National Register of Historic Places in 1975.
== History ==
Located at the north-south and east-west roadway section of the riverside town of Cornwall, Connecticut, numerous bridges have been built at this location. As early as 1762, a bridge may have been in service here. The lifespan of these bridges was not a long term one, for floods and ice would demolish them frequently.〔 Peter Vermilyea, author of ''Hidden History of Litchfield County'', states that wooden bridges had typical life spans of seven to ten years.〔 Town records list expenditures for repair and placement.〔 For many decades the current West Cornwall bridge was believed to have been constructed in 1841, as a replacement for an earlier bridge that washed away in the flood of 1837.〔 The 1841 date was even included on the National Register of Historic Places nomination and was claimed to have been supervised by Ithiel Town himself. At least one, but possibly several incarnations of these earlier bridges were known as the Hart Bridge, after a settler of West Cornwall. Local tradition states that Selectman Marcus Smith traveled to North Adams, Massachusetts to choose the timber for the bridge. The 1841 bridge may have been overseen by Ithiel Town, but the current bridge dates to about 1864 according to research by Michael R. Gannett for the Cornwall Historical Society. The center pier which supports of the middle bridge was likely reused from the previous bridge. In 1968, the State of Connecticut added the bridge to the state system and considered replacing it. A local committee in West Cornwall was created and organized to save the covered bridge, through their efforts the Connecticut Department of Transportation decided to renovate the bridge.〔 The bridge was raised up an additional two feet and steel supports were inserted to support the roadway. In 1973, the roadway was reinforced with the addition of a concealed steel deck to support the weight of traffic. This project would win the Federal Highway Administration's award for outstanding historic preservation.〔
Throughout its history, the bridge has endured against a series of disasters that threatened to demolish it. Flooding as a result of the 1938 New England hurricane and the flood of 1955, caused by the combined effects of both Hurricane Connie and Hurricane Diane, threatened to wash the bridge away.〔 In 1961, a severe ice jam threatened to destroy the bridge, but the jam was successfully dynamited.〔 The bridge also had to be repaired in 1945 after a 20-ton oil truck fell through the bridge floor.〔
