Houston-based Green Corridors is gearing up to construct prototypes for its ambitious Project Pegasi, an elevated freight bridge using automated shuttles across the U.S.-Mexico border in Laredo, Texas. With presidential approval secured in June, prototype building starts within six months, promising to transform North American trade by easing congestion at the busiest truck crossing.
Project Details and Technical Progress
Project Pegasi features an elevated guideway spanning the Rio Grande, with diesel-hybrid steel shuttles operating in platoons like a conveyor belt. CEO Mitch Carlson revealed in an exclusive interview that digital twin modeling has refined designs over three years, reaching NASA’s Technology Readiness Level 4 and targeting Level 7 soon. Prototypes for shuttles, container lifts, and terminals will be manufactured in Texas or Nuevo Leon, Mexico, with a 2-mile test track—including an S-curve—ready by August or September 2026.
- Shuttles designed digitally, including welding procedures, for Version 1 testing in 2026.
- Operational journey: 4-5 hours from Monterrey to Laredo.
- Full system: 2,500 shuttles on the guideway, running 24/7.
Addressing Border Trade Challenges
Laredo handles the bulk of U.S.-Mexico truck freight among four Texas crossings—Brownsville, Eagle Pass, El Paso, and itself—yet faces nighttime closures, fraud, theft, and emissions from idling trucks. Pegasi mitigates these by scanning cargo in Mexico, securing loads en route, and keeping drivers on their side of the border, sidestepping visa issues. Inland terminals at greenfield sites in Monterrey and Laredo will include U.S. Customs facilities at no public cost, with mobile apps aiding truckers and logistics firms.
Benefits, Costs, and Broader Impacts
Beyond efficiency gains, the project cuts transportation emissions and market inefficiencies, aligning with global pushes for sustainable supply chains. Estimated at $6-10 billion—complicated by fluctuating material prices—financing blends debt, equity, and infrastructure funds. Snubbertech, Carlson’s manufacturing firm, handles much of the build, leveraging oilfield expertise for robust production.
- 24/7 operations versus current nighttime shutdowns.
- Pre-border inspections for predictable U.S. pickups.
- Sealed shuttles reduce theft and fraud.
- Potential truck stop addition enhances logistics hubs.
As U.S.-Mexico trade surges—vital for autos, electronics, and perishables—Pegasi could set a model for automated freight corridors, boosting economic resilience while curbing carbon footprints in a carbon-constrained era.
