About the company
Missouri River Contractors, LLC, a self-certified small disadvantaged business based in Helena, Montana, delivers heavy civil construction and infrastructure preservation services to federal agencies as a prime contractor, with a footprint concentrated in National Park Service and Federal Highway Administration projects across the Rocky Mountain and Intermountain regions. The vendor operates as a limited liability partnership and is structured as a parent entity with one named subsidiary, Frontier West, LLC. All twelve tracked awards are prime contracts or indefinite-delivery vehicles; Missouri River Contractors does not operate as a subcontractor in the source data.
The vendor's capability portfolio centers on bridge rehabilitation, road and pavement construction, sludge removal, and infrastructure preservation in federally managed natural areas. Recent representative work includes a $12.8 million firm fixed-price definitive contract from the Federal Highway Administration for pavement rehabilitation, culvert replacement, and parking lot construction on the Swiftcurrent Spur Road at Glacier National Park (awarded September 12, 2024, with completion November 21, 2025); a $7.67 million National Park Service bridge preservation contract covering five distinct bridges at Yellowstone National Park (awarded May 4, 2026, ultimate completion May 24, 2027); and a $3.85 million National Park Service definitive contract for concrete repair, joint work, and in-river scour countermeasures on multiple bridges at Rocky Mountain National Park (awarded June 25, 2025, ultimate completion July 8, 2027). The vendor also holds a $600 million, five-year Yellowstone & Grand Teton MATOC awarded by the Federal Highway Administration on May 14, 2024, through May 13, 2029, which provides a framework for construction and infrastructure preservation services across Yellowstone National Park, Grand Teton National Park, and surrounding areas; two delivery orders totaling $3.76 million have been issued against the MATOC.
Customer concentration is near-total with the Department of Transportation Federal Highway Administration, which accounts for 100% of awards by count across all four customer agencies and $661.6 million (96.7%) of combined potential value across eight awards. The Department of the Interior National Park Service (National Office and Intermountain Region combined) supplies four awards valued at $22.8 million. Work is performed primarily in Montana and Wyoming across Yellowstone, Grand Teton, Glacier, and Rocky Mountain national parks. The vendor operates exclusively under full-and-open competition; total small business set-asides appear in three of the twelve prime awards, but the largest awards—the MATOC and most delivery orders—carry no set-aside designation. Activity has been episodic: one award in 2020 and 2022, two in 2024 and 2025, and three in 2026. Four awards with combined potential value of $15 million face ultimate completion within the next twenty-four months, representing recompete exposure in that window. Combined potential value across all awards is $684.2 million, though only $82.6 million (12%) has been obligated to date, reflecting the early-stage execution posture of large infrastructure contracts.
