A woman was killed when the sport utility vehicle she was driving collided head-on with a pickup truck on U.S. Route 202 in Manchester on Tuesday afternoon.

Officials say the accident occurred when the SUV crossed the centerline near the intersection with Pelton Hill Road, reports the Kennebec Journal.

Three others who were involved in the accident were taken to MaineGeneral Medical Center for treatment. Kennebec County Sheriff Ryan Reardon said their injuries do not appear to be life threatening.

U.S. Route 202 was closed for about two hours while crews cleaned up the accident.

Reardon did not say what caused the woman's vehicle to cross the centerline, and he did not release the identities of the victims.
