Support our industry

The construction industry has been hit hard under the national economic recession. We have the highest unemployment rate of any industry in the United States. The success of our industry depends on a long-term Federal Highway Bill. Knife River Corporation actively encourages you to contact your state’s US Senators or Representatives to urge them to support construction spending.

Take time to contact your members of Congress. Supporting the construction industry means direct support for American jobs and a strong national infrastructure.
