Knife River is 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.

We believe this combination of products and services has been beneficial over time, contributing to industry-leading return on investment. We operate in mid-size, high-growth markets and are committed to long-term growth and value creation.

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.
