Two drivers who suffered injuries in a head-on collision early Thursday morning on the Kansas River Bridge were in good condition Thursday afternoon at Lawrence Memorial Hospital.

Sarah A. McWilliams, 25, Grandview Plaza, was injured about 1:20 a.m. when she entered the wrong lanes to cross the bridge — the southbound instead of the northbound span. Her 1977 Chevrolet struck a 1987 Toyota driven by Emmanuel Gauna Jr., 51, Lawrence, according to a Lawrence police report.

A passenger in McWilliams’ car, James Simpson, Manhattan, was treated at the hospital for injuries.

Sgt. Mike Pattrick, a Lawrence police spokesman, said police are checking the drivers’ blood to determine whether alcohol was a factor.
