About Us

Connecting the Heartland to the World

The Ports-to-Plains Alliance

The Ports-to-Plains Alliance is a grassroots, non-profit coalition of communities, businesses, and advocates working to expand and enhance transportation infrastructure from Texas to North Dakota — and ultimately, into Canada and Mexico. Our mission is to promote the development of a modern, efficient, and safe Future Interstate Highway corridor that drives economic growth, delivers tourism, serves supply chains, strengthens national and international trade, supports agriculture and energy production, and improves quality of life across America’s Heartland.

Join us. Advocate. Invest. Move forward.

With strong regional partnerships and a shared vision, the Alliance champions the transformation of the Ports-to-Plains Corridor into a Future Interstate Highway — unlocking opportunity and connectivity for rural and urban communities alike. Together, we’re building the future.

Our Mission in Action

The Ports-to-Plains Alliance leads a multi-state effort to upgrade and expand a 2,300-mile corridor, designated in parts as Future Interstate 27. We unite more than 200 member communities, regional coalitions, and private-sector partners to support the four-lane expansion and Interstate designation of the entire corridor across nine states. Our core activities are focused on achieving this vision.

Transforming Rural America’s Transportation Future

In the mid-1990s, civic and elected leaders in Lubbock, Texas, recognized the need to extend the economic impact of Interstate 27 by upgrading U.S. 87 and U.S. 287 to the north and south. Their vision was to strengthen rural economies by capturing the growing opportunities of north-south trade. What began as a regional effort has grown into a multi-state, bi-national coalition committed to developing a modern, high-capacity highway corridor.

Today, the Ports-to-Plains Alliance supports three federally designated High Priority Corridors on the National Highway System, collectively spanning over 2,300 miles across the United States. These corridors form the backbone of a future Interstate system reaching from the U.S.-Mexico border to the Canadian border.

The Ports-to-Plains Corridor Network

Beyond the U.S., the corridor connects to key trade infrastructure in Canada and Mexico (via border crossings at Del Rio, Eagle Pass and Laredo, and along the borders of Alberta and Saskatchewan).

Ports-to-Plains Corridor
(Laredo, TX to Colorado)

This segment extends through Texas, New Mexico, Oklahoma, and Colorado, connecting to the Heartland Expressway. The corridor in Texas and New Mexico has been authorized by Congress as a Future Interstate Highway (I-27).

Heartland Expressway (Colorado to South Dakota, through Nebraska)

Extends from Denver and Limon, Colorado, through western Nebraska to Rapid City, South Dakota with a spur connecting to I-25 in Wyoming.

Theodore Roosevelt Expressway
(South Dakota to Canada)

Runs north from Rapid City, South Dakota, through western North Dakota, eastern Montana, and into Canada.
