Several train cars are immersed in the Yellowstone River after a bridge collapse near Columbus, Mont., on Saturday, June 24, 2023. The bridge collapsed overnight, causing a train that was traveling over it to plunge into the water below. Authorities on Sunday were testing the water quality along a stretch of the Yellowstone River where mangled cars carrying hazardous materials remained after crashing into the waterway.
