Wyoming interstate 2015 after a heavy April storm dropped almost 10 inches of snow

April Blizzard Causes 70-Vehicle Pile-Up on Wyoming Interstate.
As many as 70 vehicles piled up in one spot of a Wyoming interstate Thursday after a heavy April storm dropped almost 10 inches of snow on the area, authorities said.
An almost 150-mile-long stretch of Interstate 80 remained closed in both directions Thursday afternoon between Cheyenne in southeast Wyoming and Rawlins in the central part of the state because of treacherous, slick conditions that caused accidents across the area, officials said. The worst spot was near mile post 342, between Cheyenne and Laramie, two of the state's major population centers.
