Study Background

The 86th Texas Legislature passed House Bill 1079 relating to a study of the Ports-to-Plains Corridor, including an evaluation of the feasibility of certain improvements to Interstate Highway 27 (I-27), by the Texas Department of Transportation (TxDOT).

The Ports-to-Plains Corridor Feasibility Study evaluates the feasibility of, and the costs and logistical matters associated with, improvements that create a continuous flow, four-lane divided highway that meets interstate highway standards to the extent possible, including improvements that extend I-27. The study evaluates those highways that comprise the Ports-to-Plains Corridor. The feasibility study will examine two alternatives: identifying areas that are suitable for four-lane divided highway improvement or areas that are suitable for interstate highway development.

The study limits stretch 963 miles between the New Mexico and Oklahoma borders and Laredo. This includes sections of I-20, I-27, I-35, US 83, US 87, US 277, US 287, SH 158, and SH 349. The corridor is divided into three segments as shown on the map.
