Austin Transit Partnership starts planning a 3-mile light rail extension to the airport. There is no cost or schedule yet

The Austin Transit Partnership said Tuesday it is starting to plan a light rail extension to Austin-Bergstrom International Airport, Community Impact reported. KXAN also reported the announcement. Until now, the airport line was listed as a "priority extension" with no timeline.

No cost or schedule has been set. The partnership, known as ATP, is the agency the city and CapMetro created to build Austin Light Rail with money from the 2020 Project Connect tax increase.

What ATP announced

According to Community Impact:

• The route. About 3 miles from the planned Yellow Jacket station, mostly on an elevated structure, ending at a station at the expanded airport.
• Up to a year of planning. ATP will work with the airport to fit the line and station into the Journey With AUS expansion, including a new arrivals and departures hall. It will also start a new federal environmental review, which the Federal Transit Administration has agreed to streamline, and study costs, timing and funding, including federal money.
• Money. Mayor Kirk Watson, who sits on the ATP board, said he hopes the extension can fit within the existing light rail budget without new taxpayer dollars. Watson estimated the airport will generate more than $13 billion in economic activity in 2026.
• Why now. In a Nov. 10 memo, ATP officials said extending the line to the airport was the top public comment during the environmental review of the first phase.
• The airport. A spokesperson said the airport is "proactively preserving the necessary right-of-way" and coordinating its design teams.

The first phase is about 9.8 miles with 15 stations, linking Central, South and East Austin. ATP plans to break ground in 2027. Lawsuits over its funding plan are still pending, Community Impact noted.

What our records add

The council's piece of the work. On May 21 the council approved, 9-0, an interlocal agreement with ATP setting each side's staff and money for light rail design, and accepted $4 million from ATP for Transportation and Public Works. In September 2025 it approved, 11-0, an agreement on buying property for the line.

Dog's Head and the airport line. The airport extension came up during the Dog's Head debate. On May 21, Council Member Paige Ellis asked when and how the city should plan for bus service or "potential extensions, should we get light rail to the airport." The answer was to start thinking about it immediately and "don't do anything that would preclude it." In June the Urban Transportation Commission asked city staff to study whether the Dog's Head tax zone could help pay for transit, including a stop on the airport extension, Texas Rail Advocates reported. That idea faces a new petition drive. Our story explains.

The airport is growing. A city mobility report for the council's Nov. 12 Mobility Committee says Oct. 8 was the airport's fourth-busiest day ever, with 43,055 departing passengers. Construction started Sept. 29 on Concourse M, a six-gate facility. The committee's backup also lists a Sept. 30 memo on appointing ATP board members to terms that begin in January 2027.

A friendlier Capitol. The Texas Tribune reported Saturday that state efforts against Project Connect are expected to ease after the election. "I don't think we need to be on the defense the way we have in the past," Watson told the outlet.

What's next

ATP's planning could take up to a year. The airport route would follow state highways, US 183 and Hwy. 71, and TxDOT told Community Impact it coordinates with the city when local projects overlap state right-of-way. Any added cost or change to the light rail program would go to the ATP board, which includes Watson. The council's Mobility Committee meets Thursday.
