About Missouri River Contractors, LLC
Missouri River Contractors, LLC, a self-certified small disadvantaged business based in Helena, Montana, delivers highway, bridge, and road infrastructure construction and rehabilitation services to federal land-management agencies as a prime contractor under small business set-asides and full-and-open competition. The company operates as a limited liability partnership with a single named subsidiary, Frontier West, LLC, and has completed ten prime awards with a combined potential value of $680.8 million across the Federal Highway Administration and the National Park Service.
Missouri River Contractors specializes in complex infrastructure preservation in federally managed environments, particularly national parks. The concrete work spans pavement rehabilitation, bridge deck and structural repair, culvert replacement, parking lot development, slope stabilization, retaining wall construction, and wetland mitigation. Representative prime contracts include a $12.8 million firm fixed-price definitive contract awarded by the Federal Highway Administration on September 12, 2024, for the Swiftcurrent Spur Road rehabilitation project at Glacier National Park in West Glacier, Montana, covering pavement rehabilitation, three new parking lots, eight culvert replacements, signage, and campground loop road paving; a $9.76 million National Park Service definitive contract awarded May 25, 2022, for bridge rehabilitation spanning thirteen structures across Glacier National Park; a $7.41 million definitive contract from the National Park Service awarded May 4, 2026, under total small business set-aside for bridge preservation at Yellowstone National Park covering five bridges with concrete repair, crack sealing, and deck replacement; and a $3.85 million National Park Service definitive contract awarded June 25, 2025, under total small business set-aside for bridge preservation at Rocky Mountain National Park with concrete repair and in-river scour countermeasures.
Customer concentration is tightly focused. The Federal Highway Administration accounts for 97% of combined potential value across seven awards (primarily the $600 million Yellowstone & Grand Teton MATOC indefinite delivery contract and task-order work), while the National Park Service accounts for 3% across three definitive contracts totaling $21 million. The Federal Highway Administration awarded the $600 million Yellowstone & Grand Teton MATOC multiple-award indefinite delivery contract on May 14, 2024, with a five-year performance period through May 13, 2029, providing a framework for construction and infrastructure preservation services across Yellowstone National Park, Grand Teton National Park, and surrounding areas. Missouri River Contractors has placed one task order under the MATOC—a $2 million firm fixed-price delivery order issued October 31, 2025, for Rescue Creek Bridge replacement and trail construction in Yellowstone National Park near Gardiner, Montana, with completion scheduled for December 10, 2026.
Activity is sparse but substantial in dollar terms, with awards clustered in 2024, 2025, and 2026 following a four-year gap between 2022 and 2024. Three awards carrying a combined potential value of $13.3 million reach ultimate completion inside the next twenty-four months, facing recompete exposure. All ten awards are definitive contracts or task orders under full-and-open or small business set-aside designations; the vendor holds no subcontractor awards. NAICS code 237310 (Highway, Street, and Bridge Construction) applies across the portfolio.
