There's one of these low bridges In Syracuse, Ny, and this happens there often a few years ago a Double Decker Bus tried to go through and killed some people on the bus. The bridge is well marked like this one they have even added more markings. Then there is another one on Rt. 81 near Watertown, ny that is tall enough for campers but some tall trucks have caught it more than once. After all the repave jobs it is now 13'8" and the bridge has to be replaced because it got hit so good that it heaved one side of the bridge. They were supposed to put a system up that told people when they were too tall and it was supposed to direct them off the highway using the off and on ramps as a detour for them.
Think about things before you do them make life easier not harder.
