State troopers say Joyce Lorraine Tubbs merged onto U.S. 1 from an exit ramp and started driving her GMC Envoy north in the southbound lanes around 3 p.m. Saturday.
Troopers say Tubbs was driving 65 mph when she hit a Chevrolet SUV. Witnesses said the Chevrolet overturned and burst into flames.
Tubbs and the Chevy driver, David Earl Spears of Rockingham, died at the scene. Spears' wife and 13-year-old son were riding with him and were treated and released from the hospital.
Troopers say they're still investigating the wreck but think it happened because Tubbs was unfamiliar with the area.
