Interstate 91 southbound was closed in Enfield during rush hour Tuesday after a car carrier struck the Route 5 overpass at exit 49, state police said.
The accident happened around 5 p.m. when a tractor-trailer towing a car carrier attempted to cross underneath the Route 5 overpass.
According to police, one of the cars it was towing struck the underside of the overpass.
The tractor-trailer was driven by Charles Blake, 41, of Belllows Falls, Vt., a driver with New Hampshire-based KRW Auto Transport and Towing.
Blake was not injured, police said.
Debris from the collision hit a car traveling southbound, drivin by Steven Roche, 50, of 77 Bobolink Lane in Somers. Roche was not injured. His car sustained minor damage, police said.
A DOT crew arrived at the scene to inspect the bridge.
No serious damage was reported, but the accident caused a mess in the southbound lanes.
Police began to allow cars to pass the accident on the right-hand shoulder, but traffic remained congested for several hours, police said.
State police said no injuries have been reported.
