As someone deeply invested in sustainable mass transit and supply chain automation, I’m also invested in an idea that could change the world of freight transport for us all.
The global supply chain is in flux. Even before new tariffs, the nearshoring trend in North America has created an urgent demand for more innovative and efficient freight solutions.
However, despite automotive advances, transport logistics are riddled with inefficiencies—bottlenecks at congested ports, trucks idling for hours at border crossings, and outdated infrastructure struggling to meet modern demands.
But what if we could change that? What if freight could move continuously, seamlessly, and autonomously away from public roads? That’s precisely the vision behind Green Corridors, an emerging technology company tackling some of the most congested trade routes in North America.
A new era for freight mobility
Led by president and CEO Mitch Carlson, Green Corridors is pioneering a transformative approach to freight logistics, combining industrial automation with intelligent infrastructure. Their pilot projects under development include a 60-mile autonomous freight corridor between the Port of Houston and an inland terminal currently in feasibility stage, and a 165-mile corridor between Laredo, Texas, and Monterrey, Mexico in predevelopment stage. These projects will redefine the way goods progress across these critical trade arteries.
The core of the new system is an elevated guideway system where autonomous freight shuttles traverse a dedicated track to transport cargo seamlessly over these highly congested routes. Beyond incremental improvements to trucking or rail, the solution is an entirely new paradigm for freight transport. The implications are massive:
Eliminate congestion: By shifting freight movement away from roadways and onto dedicated guideways running autonomous shuttles, these corridors substantially increase safety, reduce road maintenance costs, and alleviate traffic jams that cost billions of dollars in lost productivity.
Strengthen national security: The system integrates directly with U.S. Customs and Border Protection, ensuring that every shipment is pre-scanned and approved before it crosses the U.S./Mexico border. Compared to today’s manual methods, in which only about 5% of cargo is fully scanned, this would mark a monumental shift in security and efficiency.
Reduce emissions: Freight shuttles vastly reduce emissions from semi-trucks. Likewise, the shuttles run at 30 mph versus 60 and run on rails versus rubber tires, using clean diesel fuel and electric propulsion. A single corridor could cut emissions by up to 75% while maintaining 24/7 operations.
Productivity: The trade routes Green Corridors are targeting are money-losing scenarios for traditional transport. In the proposed new model, truckers are more productive, have a higher quality of life, and able to make more trips per day.
Tailor-made for nearshoring
As nearshoring increases in North American markets, Mexico has overtaken China as the leading U.S. trade partner. This trend is a positive development in many respects; however, the infrastructure challenges of ground transport continue to hinder efficiency.
Laredo, the nation’s No. 1 port of entry, sees 18,500 trucks cross the border daily, often waiting up to eight hours. The high growth of this route, particularly as the U.S. moves further away from reliance on factories in Asia, has made it challenging for Laredo to meet the increasingly higher pressure to remain profitable and predictable for ground transport. Green Corridors removes these inefficiencies and sets a new standard for freight logistics in an era where predictability, security, and efficiency are paramount.
A national and global vision
While the Laredo-Monterrey and Houston projects are first in line, Green Corridors is eyeing a much larger transformation. As it scales, the company plans to target intelligent freight transportation corridors in major port cities such as Los Angeles, Seattle, and New York. Ultimately, the solution could scale to anywhere congested corridors are throttling economic productivity.
In its next phase, the company would like to play a primary role in reshaping shipping routes worldwide. For example, Mexico’s proposed Interoceanic Corridor, a 188-mile rail project meant to compete with the Panama Canal, could potentially use the Green Corridors’ intelligent freight transportation system to create a more efficient alternative instead. Instead of waiting weeks for ships to queue through the canal, companies could seamlessly transport freight from the Pacific to the Gulf of Mexico in hours.
The road ahead
Clearly infrastructure projects of this scale don’t occur overnight, but momentum is building. Green Corridors has already submitted its presidential permit application for the Laredo-Monterrey corridor. If approved, the project could be operational by 2030, according to my interview with Carlson. The company has aligned itself with leading engineering firms (including my own organization, Chang Robotics), financial institutions, and multiple government agencies to ensure a smooth execution.
This type of development is the future of freight—a system that operates 24/7, doesn’t clog our highways, and enhances security, while reducing environmental impact. For businesses navigating the complexities of modern supply chains, it offers the path to a more efficient and sustainable future. In an era where logistics disruptions can mean the difference between profit and loss, that future can’t come soon enough.
