Transportation Secretary Sean Duffy announced “America’s Great Corridors of Commerce,” an initiative to co-locate energy transmission lines and telecommunications infrastructure along existing federal highway and railroad rights-of-way, on Aug. 26.
The plan is designed to lower permitting burdens and costs for new power lines and fiber optic networks by leveraging transportation corridors that have already been cleared of major regulatory obstacles. The approach uses transportation infrastructure authority to advance both energy and broadband policy simultaneously.
If executed at scale, co-locating power lines and fiber on federal highway and rail corridors could significantly accelerate two of the most capital-intensive and permitting-constrained infrastructure challenges in the country: grid expansion and rural broadband deployment.
Building new transmission lines and fiber networks typically requires years of environmental review, land acquisition and permitting. By routing new infrastructure along existing rights-of-way, the initiative could bypass many of those delays while reducing construction costs.
For rural Americans who lack reliable broadband access and communities facing power reliability challenges, the initiative offers a potential path to faster infrastructure delivery. Many underserved areas are located along federal highway corridors that could serve as ready-made routes for new lines.
The DOT has not yet published detailed implementation guidance, project timelines or the full scope of eligible corridors. Key questions include which federal highways and rail lines will be prioritized and how the department will coordinate with the Federal Energy Regulatory Commission and state regulators.
The initiative reflects growing bipartisan recognition that permitting delays are a primary barrier to infrastructure construction. Both energy and broadband advocates have argued that existing rights-of-way represent underutilized assets for co-location.
Railroad industry groups will also be closely watching the initiative, as co-locating infrastructure along rail corridors requires coordination with private railroads that own and operate most of the nation’s rail network.
