Two Florida women were seriously injured early Wednesday in a wreck that jammed I-75 in Henry County during the early stages of the morning commute.

The single-vehicle crash happened just before 4 a.m. on I-75 northbound just before Jodeco Road, Henry County police Lt. Joey Smith said.

Smith said the woman driving a 2002 Jeep Liberty possibly fell asleep before losing control of the Jeep, hitting the center guard rail and overturning.

The driver was ejected, Smith said. Her passenger remained in the vehicle, but both women were taken to Atlanta Medical Center with serious injuries.

The names of the women, who are from the Orlando area, have not been released.

Several northbound lanes of the interstate were blocked for about two hours.
