Austin’s first light rail line is planned to reach East Riverside Drive, near the airport. The ride to the airport itself would take another project. In a November 10 memo to its board, Austin Transit Partnership laid out the work it plans to do on that final stretch: coordinate with the airport, begin a separate federal environmental review, and figure out what the extension might cost.
The proposal starts at the future Yellow Jacket Station on East Riverside Drive and runs about three miles, mostly on elevated tracks, to one station at Austin-Bergstrom International Airport. The extension was already a priority in the agency’s 2023 implementation plan. What’s new is the work plan: the agency says the Federal Transit Administration agreed to let it prepare an environmental assessment for the extension, and its designers will work with the airport’s team while the airport expansion is underway. The board memo puts that planning work at about nine to 12 months. It gives no date for airport trains to start running.

The federal funding profile for Phase 1 describes a 9.8-mile system with 15 stations. Its eastern branch ends at a proposed park-and-ride near the airport, just west of State Highway 71. In the sponsor’s financial plan published in that profile, the federal Capital Investment Grants share is about $4.07 billion, or 49.4% of the $8.23 billion Phase 1 total, which includes financing charges. The rest comes from Proposition A property tax revenue, both directly and through debt the plan would repay with that revenue. The Federal Transit Administration explicitly says the table does not represent a federal commitment.
The airport extension does not share that funding plan. The November memo says Austin Transit Partnership will develop a separate cost estimate, look at when its Proposition A revenue budget could cover the extension, and explore other sources, including possible federal support. The two documents answer different questions: the federal profile shows how the sponsor proposes to pay for the line that stops near the airport; the new memo sets out how the agency plans to find a way to pay for the rest of the trip.
Austin Transit Partnership’s project timeline targets 2033 for the first 9.8 miles, subject to contractor input and federal funding. For airport workers and travelers making the trip now, CapMetro’s Route 20 timetable lists service between Capitol Station downtown and the airport’s lower level. For a future train to the airport, the documents to watch are the extension’s environmental assessment and its own cost and funding plan.
