BENTON — An accident on Interstate 95, near exit 133, on Monday evening closed the highway for about an hour, and a medical evacuation helicopter was called in to transport at least one victim to the hospital.

It was unclear to a reporter near the scene in which lane the accident took place.

A LifeFlight of Maine helicopter arrived at 7:46 p.m. on the highway, according to scanner traffic.

The interstate was reopened to traffic around 8:40 p.m., according to emergency services radio messages.
