Federal Response Triggered by Montana Bridge Collapse and Train Cars in Yellowstone River

A bridge collapse in Montana caused several freight train cars carrying hazardous materials to crash into the Yellowstone River. It is unclear if any of the materials leaked. Multiple local and federal agencies responded to the incident, and initial air and water tests did not find any evidence of leaks. The river has been closed, and residents have been advised to follow instructions from local authorities. There were no reported injuries.
