Officials with the Iowa DOT report Highway 6, just east of I-80 in northeast Council Bluffs, was blocked in both directions this morning, due to an accident involving a SWITA bus and a concrete mixer truck. The crash was reported around 7:30 a.m. near Sunnydale Road. First responders reported multiple injuries at the scene. Video from the scene showed the bus was upright in a ditch, while the cement mixed was on its passenger side, partially on the road. Motorists are asked to avoid the area and find another route.
