A woman was killed early Monday after driving her vehicle off Interstate 95 into the median and striking a tree in Pittsfield.

Rae Hartford, 56, of Scarborough, was pronounced dead at the scene.

The Maine State Police responded to mile marker 143 on I-95 at 5:55 a.m., where Hartford’s 2012 Subaru Impreza was found, Shannon Moss, public information officer at the Maine Department of Public Safety, said in a news release.

One lane of traffic was closed for two hours, Moss said.

Moss said the preliminary investigation indicates speed and intoxication are considered to be likely factors in the crash. The investigation is ongoing.

Anyone with additional information is asked to call Trooper Klayton Peckham at 207-973-3700, Ext. 9.
