Lightning strike kills motorcyclist on highway Man was travelling during rush hour between Denver and Boulder Updated: 1:53 a.m. ET June 22, 2006 WESTMINSTER, Colorado - A motorcyclist died after apparently being struck by lightning while riding in rush hour traffic on a highway between Denver and Boulder, police said. Witnesses reported seeing a flash of light shortly before the motorcyclist struck the highway's center concrete divider, Westminster police spokesman Tim Read said in a statement. The man, whose name was not released, was pronounced dead at the scene Wednesday. His motorcycle came to rest about 150 meters from where lightning blasted an 18-by-8-inch crater 4 inches deep that blew chunks of asphalt across the highway and slightly damaged other vehicles. The man was wearing a helmet. The highway, U.S. 36, was closed for about two hours as police investigated.
