I added King as a possible fabricator based on your guess. I am almost certain Hartford Road is the site based on the pier and on the visible topography, which seems to match Hartford better than OH-37. Would be interesting to figure out if this bridge actually lasted until 1983...the aerials are pretty cloudy but it seems like the bridge there pre-1983 was wider than a one-lane bowstring would have been.

Very cool to see old piers reused on a modern bridge, don't see that on road bridges every day

Two comments:

1. The bowstring looks like a King to me.

2. Nice find on the pier!

Find of the day!

This could be either Hartford Road or OH-37, but I lean toward Hartford because the stone pier appears to be very similar to the one that supports the current bridge, which was built in 1983.
