Six people were injured – one seriously – in a multi-vehicle crash Thursday night on Carl Broggi Highway in Lebanon, according to the Lebanon fire department.

An SUV and a pickup truck collided head-on about 6:20 p.m. near the intersection of Stokewood Drive, said Lebanon Assistant Fire Chief Dan Roy.

The collision caused a third vehicle to stop suddenly to avoid the wreck, then a fourth vehicle rear-ended the third vehicle.

The passenger of the SUV was the most seriously injured, Roy said. Two teams of rescue workers struggled to extricate the victim before a LifeFlight helicopter transported him to Maine Medical Center in Portland.

The other five injured people were transported to Goodall Hospital in Sanford with injuries that were not life-threatening, Roy said.

In all, nine people were involved. Three people, including one child, were evaluated at the scene and did not require treatment. Multiple rescue departments were called to the scene, and the roadway, also called Route 202, was closed temporarily while Maine State Police worked to reconstruct the accident.
