The link below is a comprehensive list of Ohio's Historic Bridge Inventory and Evaluations
which now includes bridges constructed from 1951 to 1960 that were evaluated in 2004.
The table contains:
National Register (listed in the National Register of Historic Places)
Select (those eligible for listing in the National Register)
Reserve (require National Register evaluation if part of a federal undertaking)
Not Eligible / Non-Historic / Non-Select (These structures are generally exempt from from Section 106 Coordination with the State Historic Preservation Office in accordance with the Programmatic Agreement Regarding Federally Funded or Approved Highway Bridge Projects. However, diminishing examples, new information and research developments may constitute a re-evaluation of these bridges for National Register eligibility).
The list is currently in Excel format and will be updated periodically at this location. Last updated April 20, 2007.
