I–47 Future Interstate Act of 2026

This bill, known as the "I-47 Future Interstate Act of 2026," seeks to significantly upgrade a major national roadway. It achieves this by amending the Intermodal Surface Transportation Efficiency Act of 1991. Specifically, the legislation designates the entirety of United States Route 287, which runs from Port Arthur, Texas, to Choteau, Montana, as a High Priority Corridor . Concurrently, it officially designates this extensive route as Interstate Route I-47 , integrating it into the national Interstate Highway System. This designation aims to enhance transportation infrastructure and connectivity across the affected states.
