MT 41 bridge in Twin Bridges reopens

Montana Department of Transportation (MDT) officials are pleased to announce that access to the bridge on Montana Highway 41 (MT 41) near the intersection with Main Street in Twin Bridges has been restored.

“Our top priority at MDT is, and will always be, public safety,” said Andy Cullison with the MDT Bridge Bureau. “Thank you to the residents of Twin Bridges and the surrounding area for your patience as we worked to restore access.”

The bridge was closed earlier this week following a special inspection that identified the reinforced concrete pier supporting the center span of the bridge was actively failing due to deterioration of the concrete supporting the steel girders. 

MDT personnel worked rigorously to design and implement a solution. Repairs were made to the concrete pier wall foundation, bringing the bridge back up to standards. 

A close-knit community, the residents of Twin Bridges partnered with MDT as well to address and solve the problem. Local and county officials helped coordinate efforts, search and rescue helped support the bridge repair work, and local contractors supplied a barge and crane to create additional access points to fix the bridge.

“This project exemplifies how Montanans come together in challenging times,” said MDT Interim Director Larry Flynn. “We’re grateful to our hard working MDT engineers and maintenance teams that were able to identify the safety issue, fix it, and restore mobility for Twin Bridges and surrounding communities.”

A special thank you to the U.S. Bureau of Reclamation, Madison and Beaverhead counties, first responders and many others.

MDT staff will continue to monitor and inspect the bridge as part of its maintenance efforts. All bridge traffic can resume as normal.
