I have merged data from the 1992 NBI when this bridge still existed, and it matches what was already here, so this is the right bridge. The bridge that Megan referred to is a different one, as this one's location is quite a distance from any interstate highways. The Google Earth time bar shows that the bridge disappeared sometime between 1991 and 1995.
Google maps lumps this bridge in with the interstate next to it. Wood deck is really deteriorated. Pass by it frequently on my way into OKC. Hard to see on Google Maps... but its there. Neat old bridge...but I wouldn't even walk on it..you can put your feet through the decking if you tried.
Google Maps aerial view shows no bridge existing at this location.
