I–47 Future Interstate Act of 2026
Sponsored By: Senator Cornyn, John [R-TX]
Introduced
Summary
Designates US Route 287 from Port Arthur, Texas to Choteau, Montana as Interstate I‑47. The bill would add that corridor to the Intermodal Surface Transportation Efficiency Act of 1991 as a new High Priority Corridor and amend ISTEA language to assign the I‑47 number. That formal designation would support future planning and project delivery and could make corridor projects eligible for federal programs and funding, subject to later appropriations.

Interstate I-47 designation for US 287
This bill would add US Route 287 to the federal list of High Priority Corridors. The corridor runs from State Highway 87 in Port Arthur, Texas, to US Route 89 in Choteau, Montana. It would also amend the Intermodal Surface Transportation Efficiency Act to designate that route as Interstate Route I-47. If enacted, this would formally identify the corridor for federal and state transportation planning and could make it a priority for future funding and projects. The bill does not provide new funding; any construction or upgrades would need future authorization or appropriations.
