One hundred vehicles were involved in several crashes in a one-mile stretch of Colorado’s Interstate 25 during Wednesday’s blizzard, according to the Wellington Fire Protection District. The crashes apparently took place around the same time Wednesday morning about 15 miles north of Wellington. One pileup involved about 30 cars, and another snarled about 40, said Rachael Gonzales, WFPD communications specialist. Other smaller crashes in the area brought the total of vehicles involved to about 100, she said. The crashes involved rear-end collisions, vehicles sliding off the road, and some vehicles were struck multiple times, according to CSP trooper Paul Dirkes.
