There are three bridges carrying Hopyard Road (part of unsigned State Road 434) over several brooks within Devil's Hopyard State Park in the U.S. state of Connecticut. The main route of SSR 434 follows the Eightmile River and the bridges cross over its minor tributaries. All three bridges are listed on the National Register of Historic Places (as Bridge No. 1603, Bridge No. 1604, and Bridge No. 1605, corresponding to their structure numbers in the National Bridge Inventory). The three bridges are essentially identical masonry arch bridges, 38 feet (12 m) long, with a roadbed 22 feet (6.7 m) wide. All three were constructed between 1933 and 1937, in part by Civilian Conservation Corps crews, and in part with funding from the federal Works Progress Administration jobs program. All three bridges were rehabilitated in 1988, capping the arch with concrete and a waterproof membrane before restoring the roadbed.
