In Durham NC on Gregson Street is a railway bridge that has a clearance of 11' 8" . Despite signage, trucks still hit the bridge. A local business owner put up cameras to record the action. Web site is 11Foot8.com. I been watching several you tube videos of the action. Look, enjoy and pity the poor trucker who hits bridge. Even more amazing is STUPID drivers in cars who try to go around trucks when they are backing out from under bridge.
