Authorities say four people have died in a pileup involving over 30 vehicles, including six semitrailers, on an interstate in Colorado after blowing dirt made it hard for drivers to see. The crash happened Tuesday on Interstate 25 south of Pueblo. The Colorado State Patrol says dirt kicked up by heavy winds caused “brown out” conditions. It said drivers had low to no visibility. The patrol said 29 people were taken to the hospital but the extent of their injuries wasn’t known.
