Knife River is a people-first company. Everything we do starts with our team. Our talented men and women build things that last – from roads to bridges to great relationships.
We are an aggregates-based, vertically integrated construction materials company. We operate in 14 states and we’re the fifth-largest producer of sand and gravel in the country.
We have 188 aggregate sites totaling over 1 billion tons of reserves. Our aggregates are the foundation of our business, and they support our downstream products, which include asphalt and ready-mix concrete.
In addition to being a leading supplier of construction materials, we also are a provider of contracting services. We perform construction in 12 of our 14 states, with a business mix heavily weighted to public-sector projects.
Ultimately, our goal is to use our materials to build the roads, bridges and airport runways that connect people with where they want to go.
