Looked for this bridge again, 3/25/13. Didn't take the map with me, so was working from memory. Assuming I was in the right place, this bridge has been replaced.
6/4/09 Really liked this bridge! Just south of Allenwood. W on Devitt Camp Rd from jct w/US-15. Open grate floor. King Bridge Co of Cleveland. Signatures in cement from 1963 rehab at SW corner of bridge. Never saw mail boxes on a bridge before. GPS N41 06.08 W76 54.49
