Knife River Corporation

At Knife River Corporation, we pride ourselves on being a World Class leader in safety and customer satisfaction by providing outstanding construction materials and services while being a great place to work. Our company was founded in 1917 in the coal mines of North Dakota. Over the years, we have diversified our operations. Today, we are no longer in the coal business, but we have built upon our mining expertise and have grown to be among the Top 10 sand and gravel producers in the United States, according to the U.S. Geological Survey. We mine aggregates and market crushed stone, sand, gravel and related construction materials, including ready-mixed concrete, cement, asphalt and other value-added products, as well as performing integrated construction ( www.kniferiver.com )
