CONCORD — Three people were injured — two seriously — in a head-on collision Saturday afternoon on Kennebec River Road in Concord.

Police said Adrean Yates, 27, of Bingham was northbound in a 2007 Nissan Altima when the vehicle collided at about 1 p.m. with a southbound 2011 Chevrolet pickup truck driven by Kade Tibbetts, 25, of Embden.

Yates and his passenger, Kennedy Humphrey, 18, of Bingham were seriously injured in the crash, according to a statement from the Somerset County Sheriff’s Office.

Both suffered injuries considered life-threatening and were taken by a LifeFlight of Maine helicopter to Northern Light Eastern Maine Medical Center in Bangor, officials said. Their conditions were not known late Saturday.

A baby in a safety seat in the Nissan’s back seat appeared not to have been injured, officials said, but was taken by ambulance to Redington-Fairview General Hospital in Skowhegan.

Tibbetts, who was alone inside the pickup truck, was also taken to Redington-Fairview General Hospital with injuries not considered life-threatening.

Michael Mitchell, chief deputy in the Somerset County Sheriff’s Office, said the three adults were wearing seat belts.

Kennebec River Road, also known as state Route 16, runs parallel to the western bank of the Kennebec River, south of Bingham.

The cause of the collision remained under investigation late Saturday. The lead investigator is Deputy Allen-Michael Jones, and the Maine State Police are reconstructing the crash.

The Bingham and Solon fire departments and the Upper Kennebec Ambulance Service and Anson-Madison-Starks Ambulance Service also responded.
