Chicago has roughly 1,750 viaducts, many built in the late 1800s, and truck strikes are so routine that the Chicago Police Department 'gave up counting' vertical-clearance accidents — often not even ticketing because, as a CPD spokeswoman put it, the truck 'is already crunched like a sardine can with its top peeled off.' CDOT's program to raise the most-hit viaducts runs about $1.5 million each. (Reported by Heavy Duty Trucking, early 2000s.)
