Historic Bridges of Devil's Hopyard State Park

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 ft long, with a roadbed 22 ft wide, and were built using Depression-era federal jobs money. They are good examples of vernacular rustic park architecture.

History
The state of Connecticut, in developing Devil's Hopyard State Park in the 1920s, contemplated the construction of SSR 434, but funding of those types of capital projects was suspended in 1930. Funding and work crews from the Civilian Conservation Corps resulted in the grading of 1.5 mi of the road, and the partial construction of one of the three bridges in 1933-35. Funding from the federal Works Progress Administration jobs program was then applied to the project, resulting in the completion of the bridges by the end of 1937. The roadway itself was not completed until several years later. All three bridges were rehabilitated in 1988, capping the arch with concrete and a waterproof membrane before restoring the roadbed.
