ST. ?LOUIS (KMOV) -- Two people were seriously injured Friday afternoon in a one-car accident on Interstate 44 near Big Bend Boulevard, authorities said.
The Missouri State Highway Patrol said Madeline Heil, 22, of Manchester, was driving a 2001 Jeep Grand Cherokee on eastbound I-44 when she lost control and struck a concrete median.
The accident caused Heil and a passenger, 17-year-old Abigail Heil of Ladue, to be ejected from the sport utility vehicle.
Both women were taken by ambulance to St. John's Mercy Medical Center in Creve Coeur.
The patrol said Madeline Heil was driving too fast for conditions at the time of the accident, which happened around 4:15 p.m.
Traffic was backed up several miles in both directions while authorities investigated.
