FREEPORT, Maine — Interstate 295 southbound in Freeport reopened shortly after 9 a.m. Thursday after being closed for almost an hour because of what the Maine Turnpike Authority described as a “major collision” near mile 21.

At 9:51 a.m., traffic was still moving slowly and public safety officials advised caution in the area.

A Maine State Police dispatcher said five cars and a tractor-trailer were involved. Freeport fire and rescue was also at the scene, the dispatcher said.

State police continued to work to clear the crash.

Neither Freeport nor Brunswick police dispatchers had any information. No additional information was immediately available.
