A highway bridge at 7 ft., 7 in. -- what could go wrong?

Frequently in Spokane, WA, commercial truck drivers don't heed the signs and turn onto a busy street, only to find themselves stuck under an old railroad overpass. It's become a 'meme' here, it happens so often. I haven't heard of any trailers or fifth-wheels getting stuck; it must be either attentive drivers or it's a more commercial area for truck deliveries. http://www.spokesman.com/stories/2018/apr/08/truck-meets-bridge-the-story-behind-spokanes-much-/#/0
