Smolen–Gulf Bridge

The Smolen–Gulf Bridge is a covered bridge which carries State Road (Ashtabula County Road 25) across the Ashtabula River at the Plymouth and Ashtabula Township line in northern Ashtabula County, Ohio, United States. At 613 feet (182.9 meters), it is the longest covered bridge in the United States – a title formerly held by the Cornish–Windsor Covered Bridge in New Hampshire – and the fourth longest covered bridge in the world. The bridge, one of 17 drivable covered bridges in the county, was designed by John Smolen, former Ashtabula County Engineer when the idea of bridging the Ashtabula River Gulf with a wooden structure was first conceived in 1995.
