Almost destroyed my 37’ RV, on an 8’8” Low height bridge

If you reply on the GPS expect some adventures and surpries.
We casme up on a low overpass near a KOA, in Indiana, opposite Lousiville.
Almost hit one in a small town in Indiana somewhere near hwy 31. It was marked 100 ft from the bridge.
Going to dale Hollow, led us down a goat path, in tuck not rv, and someone's driveway. We saved ten miles but won't do it again.
