A bill to amend title 40, United States Code, to increase the mileage of the Appalachian Development Highway System to provide for improvements to and expansion of Corridor K in North Carolina, and for other purposes.

S 2997 amends the Appalachian Development Highway System mileage from 3,090 miles to 3,105 miles under Title 40, U.S. Code. This specific increase directly supports improvements and expansion of Corridor K in North Carolina. The bill makes a technical adjustment to the highway system's authorized mileage to facilitate these infrastructure upgrades. It does not create new funding or policy but adjusts the existing framework for Corridor K projects.
