This proposal would create a new federal grant program, run by the Secretary of Transportation, to improve roads, rail, and transit that connect to public airports. Projects must be on airport property or within 5 miles, and aim to cut traffic, add capacity, open access for underserved areas, or fix and upgrade infrastructure like bridges, tunnels, and vehicles.

Key points:

• Who can apply: States, Tribal governments, and local governments, including public airport agencies.
• What can be funded: Highway or bridge projects; public transit projects; and passenger rail projects that connect to a public airport.
• Where and why: Work must connect to a public airport and be on or within 5 miles of it, to reduce congestion, expand capacity, improve access, or rehabilitate infrastructure.
• How funds are split: At least 50% must go to projects tied to large hub airports, and at least 30% to medium hub airports.
• Cost share: The federal share follows standard highway cost-share rules; the local match can include certain federal loan assistance and airport passenger fees.
• Funding and timing: Authorizes $1 billion per year for fiscal years 2027–2031 from the Highway Trust Fund (not the Mass Transit Account).
• How to apply: Eligible governments must submit an application to the Secretary with required details.
