Bridge at site of crash lacked height warning

Other signs along roadway have faded, been lost

For years, it was a weekly event: A big box truck or bus would crash into one of the bridges along the road winding beside the Charles River. Tow trucks often were on call to free vehicles wedged between roadway and bridge.
