I found a listing date for this bridge for the NRHP; please correct me if it has since been removed. (Information taken from a spreadsheet that was said to be current as of October 17.)
Here too is the nomination form that was sent for its submission: https://catalog.archives.gov/OpaAPI/media/25340547/content/e...
Mike... The bridge is still standing and should indeed still be listed on the National Register. Thanks for finding the actual nomination form.
