High-Priority Corridors

The Ports to Plains Corridor, also known as National Highway System High Priority Corridor 38, is a highway corridor between the United States Mexico border at Laredo, Texas and Denver, Colorado. It is the southern third of the Ports-to-Plains Alliance. The reason for proposed improvements to this corridor is to expedite the transportation of goods and services from Mexico in the United States and vice versa. The proposed improvements gained momentum with the signing of the FY22 Omnibus Appropriations bill, which designated a section of the highway part of the interstate system.^[1] The Ports-To-Plains Corridor starts in South Texas and traverses through Texas, New Mexico, Oklahoma, and ends in Denver, Colorado.^[2]

The Intermodal Surface Transportation Efficiency Act of 1991 made the Ports-to-Plains Corridor National Highway System High Priority Corridor 38 in 1998. The High Priority designation, which applies to 90 routes or groups of routes nationally, does not create any additional design requirements and does not have a separate federal funding source.^[3]
