Three people were hospitalized after a four-car crash on Interstate 295 south near Exit 5A in Portland late Monday morning.

Traffic was still backed up and restricted to one lane around 12:30 p.m., said Maine State Police Trooper Robert Cejka.

The crash occurred around 11:15 a.m. when Ardo Amir, 57, of Portland, driving a 2002 Ford Focus, tried to re-enter the highway from the exit’s off-ramp, Cejka said.

Amir’s car was struck by a 2004 Toyota sedan driven by Katharine Bavoso, 23, of New Jersey.

When Jason MacLean, 41, of South Portland, tried to drive his 2008 Ford around the accident, he hit a 2012 Nissan driven by Travis Bean, 41, of West Gardiner traveling in the passing lane.

MacLean’s car flipped over and knocked down the exit sign, Cejka said.

He said MacLean was taken to Maine Medical Center to be treated for lacerations. Amir and Bavoso were also taken to Maine Medical Center for injuries, though Cejka didn’t know specifically what they were.

All three were treated and released Monday, according to Maine Medical Center.
