What is publishing's "11-foot 8-inch bridge"?

Earlier today, our intrepid James Sturdivant came across a spellbinding piece of Internet candy about a bridge too short [WATCH THE VIDEO HERE]. The video is a montage, set to the Rocky theme (always appreciated here in Philly), of trucks trying to squeeze beneath a railroad trestle with well-marked 11-feet and 8-inches of clearance. It's allegedly a masterwork of buck-passing: The railroad has installed a "crash beam" to protect its bridge, though the massive beam is also quite adept at ripping the tops off of rented box trucks. The city of Durham, NC, has installed flashing lights to warn overheight trucks. And yet, the website 11foot8.com exists for the sole purpose of documenting the vehicular atrocities.
