Our Story
Missouri River Contractors
Founded in 2016 and based in Helena, Montana, Missouri River Contractors has rapidly grown into a trusted name in heavy civil construction. Rooted in a single vision and built by a small, determined team, the company has evolved into a thriving business led by nine owners committed to excellence, innovation, and integrity. These are active leaders who work within the company and remain involved in its day-to-day operations. With deep roots in field work, our ownership team brings a wealth of hands-on experience to the table—ensuring decisions are practical, informed, and grounded in the realities of the work we do. We specialize in delivering high-quality earthwork, environmental services, and underground utility construction across a wide range of projects; from private developments to city, county, state, and federal contracts.
Our reputation for reliability and performance has earned us strong, ongoing partnerships with agencies such as the Montana Department of Transportation, the Federal Highway Administration, and the National Park Service. We’re proud of our fast-paced growth and the safety-first culture that drives every project we take on. At Missouri River Contractors, we build more than infrastructure; we build long-term relationships and lasting impact.
Frontier West, LLC
Frontier West brings over 50 years of construction expertise to our team. A Montana-based company that has long been recognized as a front-runner in bridge construction and structural concrete work, making it a perfect complement to our growing portfolio of services. After teaming together on several projects, we joined forces in 2021, as Missouri River Contractors acquired Frontier West. Frontier West is the industry leader in alternative contracting design-build projects. We partner with local engineering firms and the Montana Department of Transportation to offer fully equipped solutions from concept to completion. We also specialize in historical bridge rehabilitation projects for the National Park Service.
