SELBY, South Dakota — An Illinois man is dead after his motorcycle and a semi-trailer collided at the junction of U.S. Highways 12 and 83 in northern South Dakota.
The South Dakota Highway Patrol says 65-year-old Irwin Lyons, of Glenview, Illinois, was pronounced dead at the scene, four miles west of Selby.
The Highway Patrol says Lyons was headed west Tuesday on U.S. Highway 12 when a semi-trailer moving east on the same road turned north onto U.S. Highway 83. Authorities say the driver of the semi didn't see Lyons and continued through the intersection, where both vehicles collided.
Authorities identified the semi's driver as 40-year-old Corey Eberhart, of Java. He wasn't injured in the crash.
Authorities say alcohol and speed are not believed to be factors in the crash, which remains under investigation.
