The Heartland Expressway is first and foremost a surface transportation connection.  The vision is a connection, via 4-lane highways, from the Front Range of Colorado through Western Nebraska, and further north to the Black Hills of South Dakota. The Heartland Expressway is part of a larger vision that encompasses nine states and three existing corridors, the Port to Plains, Heartland, and Theodore Roosevelt. Together they form what is known as the Ports to Plains Corridor.

The Heartland Expressway, a federal high priority corridor, provides an essential economic development tool for rural areas in Colorado, Nebraska, South Dakota and Wyoming while facilitating domestic and international trade from Canada to Mexico.

The Heartland Expressway Association is a group of dedicated volunteers working to coordinate the activities within Colorado, Nebraska, South Dakota and Wyoming transportation departments to assure that the 4-lane construction provides a seamless artery for routing people and goods through the western states from south to north and vice versa. This corridor improvement is vital to improving safe travel, economic development, and energy development for the region and the United States.
