A tractor trailer loaded with wood products rolled over Monday on Route 121 in Casco, prompting authorities to shut down the road.

Cumberland County Sheriff’s Capt. Scott Stewart said the truck was driven by Zachary Eastman, 32, of Seabrook, New Hampshire, who was alone in the truck and was not injured. He is not expected to be charged.

Stewart said in a press release that Eastman’s truck, owned by Eastern Freight of Elizabeth, New Jersey, left the road and rolled down an embankment near Lower Coffee Pond Road.

The truck sustained only minor damage, but authorities closed Route 121 from Route 11 (Poland Spring Road) to Plains Road.

Route 121 remained closed at 7:30 p.m., more than two hours after the crash.
