Sepulveda: Over $40 Billion in Megaprojects Driving Unprecedented Growth, Infrastructure Demands in Cameron County

BROWNSVILLE, Texas — Four major economic development projects representing more than $40 billion in combined capital investments are fundamentally transforming the economic landscape of Cameron County, driving urgent demands for regional transportation infrastructure to keep pace with the influx of industry and rapid population growth.

Speaking at the monthly meeting of the South Texas Manufacturers Association at the Brownsville Events Center, Pete Sepulveda Jr., executive director of the Cameron County Regional Mobility Authority (CCRMA), outlined the immense economic powerhouses anchoring the region’s expansion:

• Rio Grande LNG (NextDecade Corporation): Located on roughly 1,000 acres at the Port of Brownsville, this $31.8 billion natural gas liquefaction and export terminal stands as one of the single largest energy infrastructure investments in Texas history.
• SpaceX Starbase: Situated at Boca Chica Beach, SpaceX’s primary Starship development, testing, and production facility represents an estimated $3.5 billion capital investment. Producing an estimated $13.5 billion in economic impact, the complex will soon feature a massive 700,000-square-foot vertical integration manufacturing plant targeted for completion in late 2026.
• Texas LNG: A premier deepwater LNG export facility situated on 625 acres at the Port of Brownsville, representing a $2.8 billion investment working alongside key infrastructure upgrades like the $16 million port connector road.
• Port Alpha (Saronic Technologies): Expected to break ground by the end of 2026 at the Port of Brownsville, this multi-phase $3 billion next-generation autonomous naval shipyard aims to mass-produce AI-powered unmanned surface vessels, creating up to 10,000 direct jobs and injecting an estimated $160 billion into the regional economy over time.

“Between the four, there are about a $40 billion investment in Cameron County, and tens of thousands of jobs that will be created and are created in Cameron County,” Sepulveda told local manufacturing and civic leaders.

However, Sepulveda cautioned that capitalizing on these unprecedented private investments requires local and state leaders to proactively address critical public infrastructure needs.

“We all heard all the positive news, but with all industry coming in, it also presents a lot of big challenges from an infrastructure standpoint, from an education standpoint, from a water standpoint, from a drainage standpoint, from healthcare standpoint, from a workforce development standpoint,” Sepulveda noted. “If we don’t stay on top of all those issues, we won’t be able to maximize the benefit of industry coming in to our area.”

Multimodal Hub & A $4 Billion Infrastructure Vision

Highlighting the region's unique geographic and logistical advantages, Sepulveda emphasized that Cameron County remains one of the few areas nationwide boasting six distinct modes of transportation: pipelines extending into Mexico, highways and freight corridors, international rail connections, commercial airports, three seaports, and commercial spaceflight operations at Boca Chica.

To keep pace with the transformations taking place across the Rio Grande Valley, the CCRMA is pushing forward with a comprehensive $4 billion system of infrastructure projects, funded largely through legislative tools granted by the Texas Legislature over the past decade.

The strategy relies heavily on broad regional connectivity spanning from South Padre Island westward into Starr County, developed in coordination with Hidalgo County, the Texas Department of Transportation (TxDOT), and the Rio Grande Valley Metropolitan Planning Organization (RGV MPO).

Key priorities highlighted in the regional framework include:

• State Loop 195 in Starr County: A TxDOT initiative bypassing the north side of Rio Grande City and La Grulla to eventually connect with Zapata and Webb counties.
• I-69 Connector Project: A 20-mile corridor linking I-69C in Edinburg to I-69E north of Harlingen.
• Outer Parkway & 2nd Causeway: Extending 20 miles east from Harlingen to link directly into the planned 2nd Causeway connecting the mainland to South Padre Island.

“The second causeway will only function if we have the I-69 Connector and the Outer Parkway,” Sepulveda explained, emphasizing the necessity of seamless regional flow given the numerous international bridge crossings stretching from Brownsville to Falcon Dam.

Looking ahead, Sepulveda pointed out that state estimates predict the population of the Rio Grande Valley will double by 2045—less than two decades away.

“We’re just trying to stay ahead of the game, trying to stay in front of any major infrastructure projects that are needed, so that again, more or less the goal is to maximize the benefit of the industry coming into Cameron County,” Sepulveda concluded.
