Project Overview

The Montana Department of Transportation is improving US Highway 2 approximately 15 miles southeast of Libby. The project will reconstruct five miles of roadway and replace a bridge over Swamp Creek. Construction is anticipated to be completed by late fall 2019.

The project includes:

  • Widening the travel lanes to 12 feet.
  • Adding 4-foot shoulders.
  • Replacing a bridge over Swamp Creek with a wider single-span concrete bridge.
  • Repaving the roadway.

Swamp Creek Bridge

Finished bridge desk

Work to replace a bridge over Swamp Creek was significantly completed in 2018. The original bridge was a narrow bridge that had deteriorated over the years and needed to be replaced. Rehabilitation and maintenance of the bridge was no longer practical.

The new bridge is a much wider, single-span concrete design that will serve motorists well into the future. The new design includes 12-feet wide travel lanes and 8-foot shoulders. The bridge will be opened to traffic later this year once improvements to the roadway are completed.

US Highway 2

Construction equipment

US 2 serves as an important lifeline for Lincoln County. The roadway has settled and deteriorated due to the soft soils and swamp-like conditions in the area. The reconstruction of the roadway will provide motorists a safer and smoother driving surface.

Due to the poor soil conditions, MDT will utilize an innovative building feature called “Geofoam” to build the roadway. Geofoam is a synthetic block compound that takes the place of regular fill dirt. It has been used successfully around the country to increase longevity and stability in areas with difficult soil conditions.
