A section of the Yellowstone River is closed while the Twin Bridges Road bridge is demolished in summer 2021.

A section of the Yellowstone River between Reed Point and Columbus is closed as a dangerous deteriorated bridge is removed from the river.

The concrete pier under the old Twin Bridges Road bridge has been so eroded by water and debris flow over the past 90 years that the Montana Department of Transportation determined it was in imminent danger of collapsing into the river and needed to be demolished.

Montana Fish, Wildlife and Parks has closed the stretch of the Yellowstone from the Indian Fort Fishing Access Site southeast of Reed Point to the Holmgren Ranch Fishing Access Site west of Columbus to all boating, floating and fishing until the demolition is finished.

Bright orange signs along the river and along the access roads alerting people to the closure will remain until the river is ready to reopen. The anticipated end date of the project is early October, although the Yellowstone could open sooner when the demolition is completed.
