A loose construction barrel caused a 13-car pile-up that shut down the northbound side of Interstate 95 in Greenwich for about two hours Sunday, officials said.
Sunday's wreck began when a car driver swerved to avoid the barrel, which was in the center lane on the northbound side of the highway near Exit 4. The accident caused some minor injuries and a two-hour shutdown of the freeway.
State police say they're still investigating. It's not clear where the barrel came from.
A spokesman for the state Department of Transportation says the agency reviewed its bridge replacement project near the crash site and determined that no materials or equipment were missing.
