A Topsham man has been upgraded to fair condition this morning after falling off his motorcycle on Interstate 295 and being struck by a passing vehicle Monday.

Adam Towers, 42, was merging onto the Maine Turnpike in Falmouth at about 11 a.m. Monday when he passed a Jeep, “started to wobble, lost control and dumped his bike,” Maine State Trooper Douglas Cropper told the Bangor Daily News Tuesday.

“He rolled around in the traveling lane and the Jeep Wrangler tried to avoid driving into him and actually ran over him,” Cropper said.

Police say Towers is expected to survive despite suffering a broken pelvis.

Cropper credited the woman driving the SUV — 62- year-old Cynthia Palmieri, of Oakland — for swerving and avoiding a direct hit on Towers. She was not charged.

“She was trying to avoid him in traffic,” Cropper said. “She’s lucky she didn’t hit another car and him.”

Towers, who was not wearing a helmet, was taken to Maine Medical Center in Portland with skin abrasions in addition to the broken pelvis.

On Tuesday morning, a Maine Medical Center spokeswoman said he was in critical condition but his condition this morning had been upgraded to fair.

Towers formerly worked as a police officer with the Topsham Police Department, including as a school resource officer at Mt. Ararat High School, until his departure in August 2007.
