“Do not hit our bridges,” one overpass sign read. “Love VDOT.”
There have been at least six incidents in recent months, including two each on the Dulles Toll Road, Interstate 66 and on the Capital Beltway. Even outside Virginia, WTOP reported a sign along the E Street Expressway in D.C. was hit Tuesday by a raised dump truck bed.

Road crews are scratching their heads as to why it’s happening. Before this recent rash of episodes, there hadn’t been many of these crashes.
