Olin's Bridge, or Olin Bridge, or Olin-Dewey Road Bridge is a covered bridge that carries Dewey Road over the Ashtabula River in Plymouth Township, Ashtabula County, Ohio, United States. The bridge, one of currently 16 drivable bridges in the county, is a single span Town truss design, and is currently the only bridge in the county named for a family. The Olin family has owned property next to the bridge since it was built. Members of the Olin family also operate a small museum and gift shop just east of the bridge at the house previously owned by Joyce Grandbouche.
