2023 Yellowstone River train derailment

The Yellowstone River bridge collapse was a train derailment that occurred on June 24, 2023, near Columbus, Montana, United States.

A bridge that crosses the Yellowstone River collapsed, causing several cars of a freight train carrying hazardous materials to fall into the water below.

The train involved in the derailment was carrying hot asphalt and molten sulfur, which are both flammable.

Officials shut down drinking water intakes downstream while they evaluated the danger after the derailment.

Greg Gianforte tweeted that he was monitoring the situation and that the state was standing by to support MRL and county officials.
