Bridge Collapse Sends Train Carrying Hazardous Materials into Yellowstone River; No Threat to Public Reported so Far

A bridge over the Yellowstone River in Montana collapsed, causing a freight train carrying hot asphalt and molten sulfur to fall into the river.
Preliminary testing has not indicated any threats to public health, but officials are continuing to monitor the situation.
The freight train's operator is working with government agencies to assess damage and plan removal of the train cars from the river.
The cause of the bridge collapse remains under investigation, though high water flow from recent heavy rains may have eroded the bridge's foundation.
Drinking water intakes were temporarily shut down as a precaution, but water testing so far shows no indication of toxic substances from the spill.
