BROWNSVILLE, Texas — In an effort to secure seamless freight movement across South Texas, the Cameron County Regional Mobility Authority (CCRMA) is partnering with federal lawmakers to extend the newly designated Interstate 27 system directly into the Rio Grande Valley.
Speaking at a monthly meeting of the South Texas Manufacturers Association, CCRMA Executive Director Pete Sepulveda, Jr., outlined a strategic vision to link Cameron County and the broader Valley region directly to Laredo via an expanded I-27 corridor.
Sepulveda revealed that U.S. Rep. Henry Cuellar (D-Laredo) has introduced legislation aimed at formally adding a segment extending Interstate 27 from Webb County down into Cameron County. If enacted, the expansion would bridge the commercial gap between the heavily traveled Laredo trade hub and key economic engines in the Valley, including the Port of Brownsville.
“So one big project, one huge connectivity project we got from last year is Interstate 27,” Sepulveda told regional manufacturing and logistics leaders. “Interstate 27 today goes from Laredo, Webb County, north all the way into the other parts of the state of Texas and the country. So our thought process… and Congressman Cuellar has introduced legislation to add the segment of Interstate 27 from Laredo all the way into Cameron County, so that will provide direct connectivity and open up the Laredo-Webb County area all the way to the Rio Grande Valley.”
Under the conceptual alignment detailed by Sepulveda, the proposed route would utilize existing highway networks and planned corridors through the Valley before connecting northwest toward Laredo.
The route would run along the existing interstate infrastructure from Harlingen westward through Mission and La Joya, into Starr County along State Loop 195, and then push north-northwest to connect with Laredo in Webb County. From Laredo, it ties into the primary north-south I-27 spine leading through West Texas toward Canada.
“That will provide direct connectivity from Laredo, Webb County, to the Port of Brownsville,” Sepulveda emphasized. “So we're talking about going on the existing interstate highway from Harlingen all the way through Mission, La Joya, and then to Starr County, State Loop 195, and go connect to Laredo and then from there it'll connect north.”
A critical advantage of pursuing the I-27 extension, Sepulveda highlighted, is its existing federal designation status under the federal highway framework.
Formerly known as the Ports-to-Plains Corridor, the 963-mile I-27 System in Texas was officially designated as a Future Interstate under the Fiscal Year 2022 omnibus appropriations bill. The broader corridor spans 26 Texas counties, connecting key international border trade gateways—including Laredo, Eagle Pass, and Del Rio—with West Texas and northern interstate routes.
Sepulveda pointed out that this pre-existing federal status gives I-27 a distinct funding advantage over other ongoing regional highway projects, such as Interstate 69.
“Big difference between I-27 and I-69 is that I-27 is already federally designated, which means that there is funding available today to start any of the improvements that are needed in the Rio Grande Valley,” Sepulveda explained.
According to background information from the Texas Department of Transportation (TxDOT), building out the full I-27 System across Texas represents a decades-long strategic initiative. The process relies on a series of incremental upgrades to bring existing trunk highways up to full interstate design standards.
Currently, approximately 124 miles of the system are signed as I-27, running from Interstate 40 in Amarillo to Loop 289 on the south side of Lubbock.
Following legislative authorization via House Bill 1079 in 2019, TxDOT conducted an extensive feasibility study on the corridor, leading to the creation of an official I-27 Advisory Committee. Once individual segments are upgraded to meet strict interstate criteria, TxDOT formalizes requests with the Federal Highway Administration (FHWA) and the American Association of State Highway and Transportation Officials (AASHTO) for official interstate signage.
For transportation leaders in Cameron County, securing the statutory language to extend that future corridor map down to the Texas-Mexico border in the lower Valley remains a top legislative priority to ensure South Texas manufacturers and shippers maintain competitive access to North American trade lanes.
