Top of lighter fluid truck sheared off in wreck

A truck dangles from the entrance of a freeway in Waterbury, Connecticut, after it crashed into the side barrier Tuesday.

WATERBURY, Connecticut (CNN) -- A tractor-trailer carrying lighter fluid failed to negotiate a curve on a freeway on-ramp bridge here Tuesday afternoon, overturning and crashing into a guard rail that sheared off the top of the trailer and the cab, according to Connecticut State Police.

The driver sustained minor injuries and was taken to a Waterbury hospital for treatment, Trooper Roger Beaupre said.

The accident caused a minimal spill of lighter fluid, and the Connecticut Department of Environmental Protection was called in to clean it up.

The tractor-trailer was traveling north on State Route 8, attempting to enter Interstate 84 east, when the accident occurred, Beaupre said. The ramp, is a high bridge spanning a river, was closed and was expected to reopen between 5 p.m. and 7 p.m. DST, after crews had finished cleaning, he said.
