AUGUSTA — Emergency crews worked Friday to right an 18-wheeler that rolled over at 6:40 a.m., blocking the southbound travel lane of Interstate 95.

The single-vehicle crash sent truck driver Nelson Plourde, 51, of Gardiner, to MaineGeneral Medical Center, Augusta, with a severe cut on the elbow, according to Steve McCausland, spokesman for Maine State Police, who are investigating the crash.

McCausland said the truck had just loaded grain at Blue Seal Feeds on Riverside Drive and overturned as it was entering the southbound lane at Exit 113.

Some grain spilled on the highway, and McCausland said the lane was expected to remain blocked until some time in the afternoon while the spill was cleared.

“State Police and Department of Transportation worked very quickly to set up cones and traffic, though slow, continues to move,” McCausland said late Friday.

Trooper Richard Plourde — no relation to the driver — said no charges are anticipated.
