A 54-year-old Augusta man died Thursday after his pickup truck left the roadway on the southbound off ramp at exit 113 on Interstate 95.

Maine State Police troopers responded shortly after 1 p.m. to the report of a single-vehicle crash, Shannon Moss, public information officer for the Maine Department of Public Safety said in a news release Thursday. The ramp was closed for about an hour and a half.

The initial investigation shows that Shaun McFarlin was driving a 2006 Ford pickup on the off ramp when he left the roadway, leading to a rollover crash. McFarlin was pronounced dead at the scene from injuries he received in the crash.

He was not wearing a seat belt, and speed is believed to be a factor in the crash.

Troopers were assisted by Augusta Fire and Rescue, the Maine Department of Transportation and AC Towing.

The crash remains under investigation.
