An obstacle course of some fashion. I said that when this came up 2 weeks ago. I’m picturing tall orange plastic markers that are on a spring mounted to the ground (so when the trucks hit it the thing doesn’t actually break) in a pattern that would force them to weave through in a way simulating the tight spots in the notch with a giant banner OVER THE ROAD that spells out without abbreviations that tractor trailers will get stuck and the ensuing penalties. It will be very ugly and obvious and that’s kindove the point. DM me DOT and I’ll draw up plans.
