SACO — A crash involving multiple vehicles hampered the morning commute on the Maine Turnpike near Saco on Monday morning.

According to State Police, several vehicles collided on the Maine Turnpike at mile 34 in Saco, including a tractor-trailer truck.

The northbound lanes of the turnpike were shut down, but were reopened to traffic an hour and 45 minutes later, although some slowdowns and backups remained while the accident scene was cleared.

Steve McCausland, spokesman for the Maine Department of Public Safety, said troopers received information that a southbound car went out of control and collided with a big rig on the turnpike.

The truck then crossed the median and struck a car on the northbound side, McCausland said. The operator of the second car involved in the accident sustained non-life threatening injuries.

Both the truck and the second car came to rest off the roadway.

According to McCausland, the vehicle that started the chain of events did not stop and is described only as a small maroon car.

Troopers have not said what caused the crash, but it happened as a mix of wet snow, freezing rain and rain moved through southern Maine.

Speeds were reduced to 45 mph for the length of the turnpike as the storm moved through the state.
