说明

This morning an 18 wheeler carrying cars looking to take the 91-N onramp at State and Trumbull blocked traffic until they could get a passer-by to watch if they were going to hit the overpass.

The Trumbull street overpass has no height markings in either direction (see attached).

I'm not an expert on road signage, but I thought it was standard practice to mark the height of highway bridges?
