BOWDOINHAM — A Massachusetts woman and her 9-year-old daughter remained hospitalized Monday night following a single vehicle crash that destroyed their car and caused traffic on Interstate 295 in Bowdoinham to back up for several miles Sunday afternoon.

Steve McCausland, spokesman for the Maine State Police, identified the victims of the crash as 39-year-old Angela Andrade and her daughter, Caitlyn Andrade.

A nursing supervisor at Maine Medical Center in Portland said the 9-year-old was in critical condition. Her mother was listed in satisfactory condition on Monday evening.

According to Trooper Niles Krech, who arrived at the crash scene just moments after it happened, Andrade’s 2007 Honda Accord was heading south on Interstate 295 when it veered off the road before crossing back into the southbound travel lanes. Her car then entered a median strip and rolled over, before settling on its roof.

Krech said a witness told him that Andrade appeared to have reached into the rear seat area just before the crash. Krech and several motorists had to dig a hole in the ground in order to pull Andrade out through a window.

The girl, who was trapped in a booster seat in the backseat of the car, had to be extricated by firefighters.

The crash, which took place around 3:45 p.m., delayed southbound traffic for nearly three hours.

The cause of the crash remains under investigation.
