That happened about a year to year and a half ago if I remember correctly. It closed that overpass down for quite a while for repair. Luckily it wasn't one that was a major road. I lived in Hays for about 6 years.

That's hilarious, and it prompted me to read up on the incident. Seems the bridge was repaired in under six months for the tune of about $500,000. Maybe the bridge was re-named for the trucking company that paid for it? (Ha)
