An Ashley County man was killed in a single-vehicle accident Wednesday night on U.S. 425 about eight miles north of Hamburg.

Lem Lambert, 73, of Fountain Hill, was traveling east on Arkansas 8 when his vehicle ran through a stop sign where the highway intersects with U.S. 425. The vehicle then ran off the east side of U.S. 425 and hit a dirt embankment before hitting a tree, according to an Arkansas State Police preliminary accident report.

The accident occurred at 7:25 p.m. The weather was clear and the roadway was dry.
