Austin Mayor Kirk Watson has announced that public transportation officials will begin planning a light-rail extension to Austin-Bergstrom International Airport, a project that would mark the first extension of the city's forthcoming light rail system. The move comes as Austin Transit Partnership prepares to break ground in 2027 on the main 9.8-mile line running through the city's core, and as the airport itself logs record passenger traffic.
What Watson Announced
Planning for the airport extension is at an early stage. According to the Austin American-Statesman, officials are exploring financing options for an airport rail connection.
Watson discussed connecting the airport and rail projects.
How the Current Route Would Connect
The light rail system now in planning is slated to include nearly 10 miles of track across north, central and east Austin, running between 38th Street and Oltorf Street, with a branch to Yellow Jacket Lane. The proposed airport extension would connect Austin-Bergstrom to the light rail system, according to the Statesman's report.
That alignment would come close to, but not reach, the airport under the currently approved plan. A separate Austin American-Statesman report from January described the main line as running near — but not to — Austin-Bergstrom, noting that future extensions could bring rail farther east to the airport. Back in February 2024, KUT reported that the airport extension was an unfunded priority excluded from the federal environmental review process because there was no money for it at the time. ATP told KUT then that if additional funding became available for the priority extensions, the agency would immediately work with the FTA to fold it into the project.
A System Already Scaled Back Once
Austin voters approved Project Connect in 2020, including a voter-approved property-tax increase for transit improvements. Early plans envisioned a broader system, but local officials later scaled it back to its current 9.8-mile route, according to the San Antonio Express-News. The system approved in 2020 comprised 27 miles of service.
Federal officials have approved the project's environmental study, and ATP has secured major construction contracts, the Statesman's report states. Still, the federal government has not yet awarded a roughly $4 billion grant that ATP officials are counting on, and the project also faces outstanding court challenges, per that same reporting.
The Price Tag Keeps Moving
Just how much the project will cost depends on which report you read. The Statesman's January report put the estimate at roughly $7.1 billion, while KXAN reported that the latest data from September showed the project now totals $8.2 billion. ATP is seeking $4.1 billion in federal funding, which KXAN said would cover about half the project's cost, and the station noted the grant had not yet been awarded. KXAN also reported that the project's two primary funding sources are local tax revenue and federal grants. ATP expects groundbreaking in 2027.
Record Crowds at Austin-Bergstrom
The push for an airport rail link comes as Austin-Bergstrom notches new traffic records. The airport set a one-day departure-traffic record in October, according to the Statesman's report.
Austin-Bergstrom is also undergoing expansion work through Journey With AUS.
For now, Austin's own airport connection remains in the early planning stages, with cost and funding questions still to be worked out before any track gets built.
