Riverdale Road Bridge is a covered bridge spanning the Grand River in Morgan Township, Ashtabula County, Ohio, United States. The bridge, one of currently 16 drivable bridges in Ashtabula county, is a single span Town truss design. During its renovation in 1981, the floor was rebuilt and glue-laminated wood girders were added. Previously, center steel bracing had been replaced under the bridge in 1945. In 1987, a new concrete abutment for additional support was added after the road at the east end of the bridge washed out.
