Montana’s Department of Transportation is moving ahead with a $4.7 million replacement of the Farm to Market Bridge in Libby, following severe flooding along Libby Creek last December that left the structure badly damaged and the road closed to local residents.

Background

The bridge, located at mile marker 2.6 on Secondary Highway 482, was heavily damaged when Libby Creek flooded in December 2025. The closure has disrupted daily travel for residents on the south side of the bridge, who must now take longer routes into town. MDT moved quickly to allocate emergency funding and begin the permitting and planning process needed to get a replacement project underway.

The situation mirrors infrastructure challenges faced elsewhere in northwestern Montana. Earlier this year, Senator Steve Daines secured a $3 million federal grant for the Glacier Creek Road replacement near Condon after a similar bridge closure disrupted access for local communities.

Project Details

Construction on the replacement bridge began in July. The new structure will be both longer and wider than the original, and is specifically engineered to handle future high-water events on Libby Creek.

Luke Francis, a project delivery engineer with MDT, acknowledged the real impact the closure has had on the community. “It certainly has an effect for folks who especially live on that side of the bridge and need to go into town — it adds time to their commute,” he said.

Francis described the design priority clearly: “The main goal around the whole design of the new bridge is to keep this from happening again in the future.”

Farm to Market Road will remain closed for the duration of construction. MDT has encouraged residents with questions or concerns to reach out to the department directly.

Timeline

MDT expects to have the new bridge completed by February 2027, though officials noted that delays from beam delivery schedules or adverse weather conditions could push that date back. The project follows the emergency funding allocation and months of permitting work that preceded the construction start this summer.

Broader Context

The Libby project is part of a broader pattern of flood-related infrastructure strain across Montana in recent years, as communities grapple with aging road and bridge networks tested by increasingly severe weather events. State and federal funding have both played roles in addressing emergency repairs, with MDT and the congressional delegation working to move resources to affected areas. Residents in Lincoln County will be watching the February 2027 target closely as winter approaches and detour routes continue to add travel time for those living south of the damaged crossing.
