BRADLEY, Maine — Maine State Police are investigating a head-on collision Wednesday afternoon that sent three people to the hospital.

The accident happened about 2:20 p.m. on Route 178, near the Milford town line, when a northbound Ford Explorer crossed the centerline and drove into the path of a southbound Nissan Xterra, Trooper Michael Johnston said.

Johnston said the accident prompted police to shut down the affected section of Route 178 for about 25 minutes. Traffic was reduced to one lane for another 45 minutes or so. Fire and emergency medical personnel from Bradley, Old Town and Orono assisted at the scene, he said.

Johnston declined to release the names of the people involved, saying that the crash investigation was in its initial stages, but he did say that both drivers and a male passenger in one of the vehicles were being evaluated at Eastern Maine Medical Center in Bangor.

None of their injuries were believed to be life-threatening, he said.

Johnson said a young child riding in one of the vehicles also was taken to the hospital as a precaution but was found to be uninjured.

The driver of the Nissan was a Bradley resident and the three people riding in the Ford were from Bucksport, he said.

No further information about the victims’ medical conditions was available Wednesday evening.
