Police say speed contributed to a single-vehicle crash on Monroe Road Thursday morning that sent the driver to a Bangor hospital with a head injury.

Waldo County Chief Deputy Bob Keating said 61-year-old Michael S. Jordan of Winterport was headed north on Monroe Road in a 2003 GMC pickup at about 11 a.m. when the accident occurred. Witnesses at the scene reported that the truck was traveling at a high rate of speed as it approached the intersection of Monroe Road and Route 69.

Keating said Jordan apparently lost control of the truck, went into a skid and slid sideways into a ditch on the southbound side of the road. The truck continued into a small rock wall, Keating said, where it rolled at least twice before coming to rest on the passenger’s side. Jordan was ejected from the vehicle upon impact.

Winterport Fire and Ambulance responded to the scene and transported Jordan to Eastern Maine Medical Center in Bangor, where he is being treated for a head injury. Keating did not know at this point if Jordan’s injuries were life-threatening.

Excessive speed was a contributing factor in the crash, Keating said.

Waldo County Sheriff’s Deputy David Mushrall was the primary officer at the scene, and he had assistance from Lt. Jason Trundy. Deputy Ben Seekins is conducting the accident reconstruction.
