An unusual traffic accident at Route 140 and Sandymount Road, one of Carroll County's most dangerous intersections, sent a woman to the hospital about 3:30 p.m. yesterday.
State police said 43-year-old Melinda W. Fisher of Finksburg was treated and released at Carroll County General Hospital after her 1989 Plymouth Voyager van was struck by a loose wheel from a tractor-trailer.
Investigators said 38-year-old Adrian D. Frock of Westminster, a driver for the Harvey Salt Co., was northbound on Route 140 and slowing for a yellow traffic signal at the intersection when he heard a loud "pop" and saw his outside left rear wheel rolling past the cab of his tractor-trailer.
