The Arkwright Bridge is an abandoned historic bridge formerly carrying Hill Street over the Pawtuxet River in the Arkwright mill village in central Rhode Island. The river forms the border between Cranston and Coventry. The bridge was built in 1888 by Dean & Westbrook for the Town of Coventry and the Interlaken Mills (later known as the Arkwright Mills). It is the longest surviving 19th century truss bridge in Rhode Island, and was added to the National Register of Historic Places in 1978.
