DURHAM — Four people were injured in a collision at the intersection of Route 9, Plummer Mill and Swamp roads shortly before noon on Friday.

Police identified them as driver Christopher Grant, 17, of Durham, his passengers Kylea Roy, 19, of Lisbon and Danielle Holbrook, 17, of Durham and driver Michael Lupardo, 59, of Auburn.

A third passenger in Grant’s vehicle Joshua Charette, 19, of Durham escaped injury.

All complained of back and neck pain and their injuries were not considered life threatening, Androscoggin County Deputy Sheriff Craig MacMillan said.

Lupardo was driving north on Route 9 onto Plummer Mill Road and Grant was driving south on Route 9 onto Swamp Road when their vehicles collided, he said.

The intersection, located midway through a winding hill on Route 9, has been the scene of many accidents over the years. MacMillan said three neighboring residents stopped to complain about the intersection. It is sometimes referred to as “dead man’s curve.”

The injured were taken to Central Maine Medical Center in Lewiston by ambulances from Durham Fire and Rescue, Lisbon Emergency and Freeport Rescue.

Grant’s 2000 Subaru and Lupardo’s 2010 Toyota Prius were demolished in the 11:32 a.m. crash.
