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

Wasn't that long ago p/u trucks were not allowed on the southern or northern state pkwys, period. Vans had to have windows and seats, no signs on the side. If you got to the toll booths with one a state trooper would come get ya. I remember many a 18 wheeler stuck under one of the bridges near my house, load spread all across the road.
