'Can Opener Bridge' railroad trestle

A low bridge in North Carolina is shaving the tops of trucks. In fact, it happens so often one man has made it a mission to document the moment of impact.

It's a bridge over troubled traffic. A bridge too low, for trucks too tall, and for the past 5 years Jurgen Henn has been using cameras to record the results, and posting them on his website "11Foot8".

That happens to be the official clearance of the Gregson Street railroad trestle in Durham, North Carolina, affectionately known as the, "can opener bridge."
