A serious crash left a truck dangling off Interstate 495 in Harvard, Massachusetts, and causing heavy traffic delays Wednesday, police said.
Images from the scene showed a box truck completely off the highway on the Stow Road bridge, near the Boxborough line. The truck's cab was in a ditch, with one wheel still perched on the side of the highway.
Other vehicles were crashed on the road as well.
It wasn't immediately clear if anyone was hurt, or how badly.
