SOUTH PORTLAND — A South Portland woman escaped serious injury this morning when she lost control of the car she was driving on Interstate 295, slid into the median and rolled over.

Lois Elwell, 58, was headed northbound at mile 9 in Falmouth at 11:15 a.m. when she lost control of the vehicle as she was looking at a rock wall in the median, said Trooper Douglas Cropper. She spotted a car to her right, swerved left and lost control, going over an embankment and hitting small trees before the car rolled onto its roof.

Elwell was able to climb out of the car with help from passersby and was taken to Maine Medical Center for evaluation. Traffic was briefly delayed as rescue workers responded.
