It started around 9:20 yesterday morning when two semis crashed on an icy bridge near Rifle, blocking both eastbound lanes for about 4 1/2 hours. The State Patrol says it investigated 16 crashes in Garfield County, most involving one vehicle. The roadways were snow-packed and icy in many areas of the county.
