The U.S. Department of Transportation has unveiled “America’s Great Corridors of Commerce” (AGCC), a new federal initiative aimed at transforming existing highway and railroad rights-of-way into shared corridors for electric transmission lines, fiber optic cables, water pipelines and other critical utilities.
The voluntary program, administered through the DOT’s Build America Bureau, is designed to accelerate utility deployment, shorten permitting timelines and create an additional revenue stream that could help finance repairs and upgrades to roads, bridges, tunnels and rail lines located along the same corridors, according to the department.
Under the proposed model, state departments of transportation and railroads could lease portions of land alongside highways and rail tracks, as well as space within shared utility tunnels, to private “corridor managers.” These companies would be responsible for overseeing the design, development, operation and maintenance of the additional infrastructure.
Transportation Secretary Sean Duffy said in an Aug. 26 announcement that using land already controlled by transportation agencies could reduce project costs by avoiding the need to acquire new private property. He also said some projects could qualify for categorical environmental exemptions, potentially allowing work to move forward without undergoing longer environmental reviews.
Revenue generated through utility leases would then be directed back toward repairs and improvements to the roads, bridges, tunnels and railroads within the corridor, the department said.
DOT emphasized that the initiative is based on public-private partnerships and is intended to expand transmission capacity, fiber networks and other infrastructure “at no additional cost to the taxpayer and no impact to the safety of existing transportation assets.”
Duffy presented AGCC as part of a broader effort to reduce infrastructure costs, accelerate permitting and support advanced manufacturing and artificial intelligence, including the continued development of data centers.
“America has always been at the bleeding edge of innovation. But we will lose the race to develop the technologies of the future if we cannot lower costs and get the government out of the way,” Duffy said.
“By working with the private sector to combine our existing transportation network with transmission lines, fiber optic cables, and other critical infrastructure, we can make energy more affordable and fuel American industry for generations to come.”
Build America Bureau Executive Director Morteza Farajian described AGCC as a voluntary program that would give public agencies and private-sector partners “new, efficient, and effective choices” for developing “smarter and better integrated corridors.”
“America can’t wait decades for modern utility and transportation infrastructure,” Farajian said. “By leveraging our existing transportation rights-of-way and bringing in private sector partners, we are charting an innovative path forward for a new age of infrastructure delivery established on strong partnerships, aligned interests, cutting through red tape and bureaucracy, collaboration, and efficiency.”
Transmission capacity emerges as a central challenge
The DOT release points to a widening gap between the United States and China in transmission infrastructure. According to the department, China has constructed more high-voltage transmission lines over the past 15 years than the United States has built throughout its entire history.
The issue is becoming more pressing as new power plants come online across the U.S. While generation capacity is expanding, the department argues that the ability to deliver affordable electricity to fast-growing communities and major manufacturing hubs remains constrained by limited transmission capacity.
Fiber optic infrastructure faces a similar bottleneck.
DOT says fiber networks are increasingly essential to semiconductor manufacturing, hyperscale data centers, smart transportation systems and other “technologies of the future.” With demand for fiber expected to double by 2029, the department argues that the U.S. needs new approaches to accelerate deployment.
Private capital aimed at transportation backlog
AGCC is also being positioned as a potential tool for addressing what the department describes as a “multi-trillion backlog” of upgrades needed across the nation’s existing transportation infrastructure.
By combining transportation rights-of-way with private investment in utility infrastructure, the initiative is intended to bring additional capital into corridors that already contain roads, tunnels, bridges and rail lines, helping keep those assets in service while new infrastructure is developed alongside them.
The proposal has attracted more early interest than opposition, although concrete positions from railroads, utilities and state transportation departments are still emerging.
Stakeholders are now assessing several practical questions, including how lease terms and revenue-sharing arrangements would work, what environmental and safety reviews would be required for utility construction inside active highway and rail corridors, and whether AGCC would receive dedicated federal funding or depend entirely on private capital and revenue generated through leases.
The Build America Bureau has published a Request for Information on the proposed AGCC model and is accepting public comments through Sept. 12.
Following that process, the bureau plans to select up to five initial priority corridors. Those corridors would receive technical support, assistance with streamlined permitting and public-private partnership models intended to help scale grid infrastructure.
The initiative therefore represents a potential shift in how the U.S. approaches both utility expansion and transportation infrastructure investment: rather than treating roads and rail lines solely as transportation assets, the federal government is proposing to use their existing rights-of-way as platforms for a broader network of critical infrastructure.
