The DOT’s mission is to serve the United States by ensuring a fast, safe, efficient, accessible and convenient transportation system that meets our vital national interests and enhances the quality of life of the American people, today and into the future. Agencies that fall under the DOT include the Federal Aviation Administration, the Federal Highway Administration, the Federal Transit Administration and the Maritime Administration.
Along with the way, the DOT spends over $1 billion annually on products and services provided by small US Department of Transportation businesses. Bids are surprisingly diverse; you’ll find requests for educational services, office equipment, copywriting, data base management, etc., alongside the typical construction and engineering projects. So, whatever business you’re in, there’s a good chance that the DOT could be interested.
