LEWISTON — A Lewiston man was transported by United Ambulance Sunday afternoon after his motorcycle and an SUV collided. 

The driver of a black 2008 Chrysler Pacifica was pulling into his driveway at 139 South Ave. when his vehicle was struck by a green 1994 Harley-Davidson motorcycle, according to Lewiston Police Sgt. Danny Lachance. He was the only one in the vehicle at the time of the crash.

The motorcycle operator, Marcus Hamby, a 38-year-old man from Lewiston, was transported to Central Maine Medical Center by United Ambulance with serious injuries, according to Lachance. His condition as of Sunday evening was unknown.

The driver of the SUV, a 69-year-old man from Lewiston, was unharmed but visibly shaken.  

Witnesses at the scene appeared to be disturbed by the incident, and tenants of a nearby apartment claimed to have “heard the bike racing up and down the street” after which they heard a loud bang. 

The bike was totaled and towed from the scene, and the SUV sustained “a lot of rear end damage,” according to Lachance.

The name of the SUV driver was not available Sunday night. 

Lachance said speed is believed to be a factor in the crash, but the exact cause still remains under investigation. 

South Avenue was closed from Mary to Sunset streets to investigate and clear the scene. 

Lewiston Fire and Police departments responded to the scene, along with United Ambulance.
