A 90-year-old Lovettsville woman died Tuesday in a three-vehicle crash on Route 9.

A Virginia State Police spokesperson said Jean Ballantyne Gearhardt died almost two hours after the 5 p.m. crash at Inova Loudoun’s Cornwall campus in Leesburg.

Gearhardt, according to the spokesperson, was driving a 2003 Mercury Sable west on Route 9 about four-tenths of a mile near Route 704 when she crossed the center line into oncoming traffic and struck two GMC Sierras.

The driver of one vehicle was not injured. The second driver and a passenger were treated for non life-threatening injuries.

The crash is under investigation by Trooper C.L. Martin.

Gearhardt, the spokesperson said, was wearing a seatbelt.
