A three-vehicle crash on Interstate 295 southbound near the Fore River Bridge in Portland early Wednesday afternoon injured two people and backed up traffic for more than an hour.

Two cars and a pickup truck crashed around 1:15 p.m. just north of Exit 4, leaving two people with injuries that were not considered life threatening, said Portland Deputy Fire Chief David Jackson.

A door of one of the cars was damaged in the crash, so firefighters had to pry the door open to get inside, Jackson said.

“It just backed up traffic for a while,” said Jackson. Firefighters cleared the scene by around 2:15 p.m.

State police are handling the accident investigation.
