Houston-based Green Corridors is gearing up to construct prototypes for its ambitious "Project Pegasi," an elevated freight bridge spanning the U.S.-Mexico border in Laredo, Texas, using automated shuttles. With presidential approval secured in June, prototype development starts within six months, promising to transform cross-border logistics at the nation's busiest truck crossing.
Project Details and Development Timeline
Green Corridors' plan features a guideway across the Rio Grande with diesel-hybrid steel shuttles operating in platoons, likened to a conveyor belt for steady freight movement. CEO Mitch Carlson revealed in an exclusive interview that digital twin modeling has refined designs over three years, reaching NASA Technology Readiness Level 4 and advancing to Level 7 soon. Prototypes for shuttles, container lifts, and terminals will be built starting in 2026, with a 2-mile test track featuring an S-curve ready by August or September.
- Shuttles digitally designed, including welding procedures—not off-the-shelf tech.
- Manufacturing in Texas or Nuevo León, Mexico.
- Full operation: 4-5 hour journey from Monterrey to Laredo.
- Scale: 2,500 shuttles on the guideway.
Key Benefits for Trade and Security
Laredo handles the bulk of U.S.-Mexico truck traffic among Texas gateways like Brownsville, Eagle Pass, and El Paso, where congestion, nighttime closures, and theft plague operations. Project Pegasi addresses these by running 24/7, pre-scanning cargo in Mexico for predictable U.S. inspections, and segregating drivers—U.S. north of the border, Mexican south—to sidestep visa issues. This minimizes fraud and theft once containers are sealed, while cutting emissions through efficient automation amid rising freight demands.
- Reduces cross-border truck idling and inefficiencies.
- Provides CBP inspection facilities at no public cost.
- Inland terminals at greenfield sites near Monterrey and Laredo.
Financing, Challenges, and Broader Impact
Estimated at $6-10 billion—a moving target amid volatile material costs—the project blends debt, equity, and infrastructure funds. Green Corridors, with 20 employees and manufacturing muscle from Carlson's Snubbertech, eyes patents for shuttle loading and apps for truckers. While permit hurdles remain in Mexico, success could bolster North American supply chains, echoing automation trends in global logistics that enhance resilience against disruptions like pandemics or tariffs. By easing the $800 billion annual U.S.-Mexico trade flow, it promises safer, greener freight corridors vital for economic integration.
