Rail To The Austin Airport Is Back On The Table—After Costs Soared And A Voter Bait-and-Switch

Austin’s airport used to be super convenient but it’s outgrown itself. There are just too many passengers for the size of the facility, at peak times it can be nearly body to body as you navigate through the terminal. What was once curb-to-gate in minutes, security wait times on peak travel days can be quite long. And traffic gets backed up heading into and out of the airport. There’s a long trek across the road and through a parking garage, up and down levels, to get to Uber or taxis. They’re building a new terminal and a new headhouse. The airport’s solution is to get (a lot) bigger. It will never recapture the ease of a smaller airport, and it’s going to mean more walking and showing up even earlier. One thing Austin doesn’t have is rail to the airport. Voters approved higher property taxes in 2020 to pay for it, but the cost of the project ballooned and train ambitions remained – but the airport connection got axed to save money. Now the mayor wants to start the process of planning again for a train to the airport. The much smaller light rail system now being developed will cost nearly double what was once estimated, even though it won’t reach the airport when it’s supposed to open in 2033. But since the airport is building an entirely new face to the facility, it makes sense to plan for how a train would approach and where the station would go. Plus, they’re going to be looking to have the airport pay for a portion of it. That’s part of what the mayor means when he talks about rail reaching the airport without new tax money. Mayor Kirk Watson lays out a three-mile extension of the planned train, mostly elevated, with a station at the airport. He says the Federal Transit Administration has agreed to a streamlined environmental review, and the next nine to twelve months will be spent working through costs and funding. His challenge is to deliver it “within our existing budget approved by voters – no new taxpayer dollars.” Latest #WatsonWire: It’s time to start the process to get rail to the airport. For years, our Austin Bergstrom International Airport (ABIA or AUS) operated beyond the capacity it was originally designed to accommodate. That’s a sign of success, and a reminder that we can’t build Austin’s future relying on infrastructure designed for its past. We need to envision a successful future and prepare for it. The “Journey With AUS” expansion project is delivering significant improvements in building the kind of airport a growing, globally connected city like Austin needs for decades to come. As we build a better airport, we also need to think about how we’re going to get people there to catch their flights and how to get them out of there to participate in our city. A world-class airport needs a multimodal, world-class transportation system to connect to it. Sure, we need to improve roadway access. And we also should give people more choices about how they travel. We need to have the same long-term vision for Austin light rail that we’ve had for ABIA. An airport rail connection has been part of Austin’s long-term transportation vision for years. With Journey with AUS, we have a chance to plan these projects strategically rather than trying to connect them after the fact. Until now, Austin Transit Partnership (ATP) has appropriately prioritized navigating the Federal Transit Administration (FTA) process for phase 1 of our system. This year, ATP received the important Record of Decision (ROD) from FTA and completed, in record time, the National Environmental Policy Act (NEPA) process for phase 1. In addition to getting the ROD and completing the NEPA process, I’ve wanted all major design and construction contracts in place and assurance that all of our financial decision-making is guided by a financial stewardship protocol before ATP takes any other big next steps. We have the ROD, the NEPA process is complete, the major contracts are in place, and the financial stewardship protocol is being followed. With these important milestones met, we can now take a major step: ATP will start the planning activities for a potential extension to take Austin light rail all the way to the airport.

The successful 2020 vote for a $7.1 billion project came when voters were home during the pandemic and governments were spending unprecedented sums on Covid relief. The city’s election explainer lays out a Blue Line running through downtown to the airport, an Orange Line connecting north and south Austin, and a downtown tunnel. There were also commuter rail and bus improvements, plus $300 million for housing intended to ‘prevent displacement’ along the transit corridors. The ballot itself pitched airport rail. Voters approved an additional 8.75 cents per $100 of taxable property value, described as $437.50 a year on a home with $500,000 of taxable value, with federal funding expected to cover about 45% of the cost. Then the rail cost estimate exploded. By 2022, the original rail component had gone from $5.8 billion to $10.3 billion. That was blamed on inflation, land costs and construction costs but it was also the result of design changes to add more undeground tunneling. Without enough money, the connection out to the airport was dropped. The train got chopped from 20 miles to 9.8 miles. 26 stations down to 15 It lost airport servic and a downtown subway And the cost went from $5.8 billion to $8.2 billion With opening delayed from a planned 2029 reaching the airport to 2033 without it. The airport got dropped from ‘phase one’ and became labeled a ‘preferred priority extension’ if additional funding materialized. Now The Idea Is To Have The Airport Pay For Part Of It The Mayor repeatedly connects the rail extension to the airport’s ‘Journey With AUS’ expansion program. Austin is rebuilding its terminal frontage, roads and parking arrangements. And it’s building a new concourse. This is when you want to reserve space for a rail station. Journey With AUS uses airport revenues, airport revenue bonds, passenger facility charges and federal aviation grants. The airport sold $1.18 billion in May and plans $4.2 billion more through 2030. That money is spoken for, but the city owns the airport and it generates tremendous revenue. There are limits on what it can do with the money – the federal government makes grants and doesn’t want that money diverted. However, In 2021, the FAA began allowing on-airport rail infrastructure to receive airport funding even when the broader line serves people who aren’t using the airport. And 2025 FAA guidance says airports can contribute to ground access projects, including facilities beyond airport the property, provided airport funds support the airport-related share. So the airport link can open up airport funds now, as well as avoiding duplicate construction. The mayor frames the effort as “no new taxpayer dollars” but that’s different from “no new airport dollars” and the airport is owned by taxpayers. The Rail System’s Financing May Be Illegal, But The Election Could Change That The city created a separate public nonprofit corporation to pay for the train, so that the city itself wouldn’t be the one incurring debt. Then it held an election about the property tax rate, instead of one authorizing the city to borrow a specified amount of money. The city collects the property taxes and transfers the money to the special corporation which issues and pays interest on the bonds. Normally, in Texas, the city would have to specify an amount of debt to raise. If they later wanted to take on more debt, they’d have to go back to voters. Instead, they raised taxes by a specified amount and dedicated that tax stream to the project. Basically the city isn’t issuing the bonds, and isn’t taking on debt. The city also says it transfers the money each year, but future city councils could just stop making the transfers (winky, winky). There’s no city debt so they didn’t have to follow state rules for the city issuing debt. So property taxes support the borrowing, but the city isn’t mkaing a binding multiyear promise. There’s no debt. The state’s attorney general said this was completely illegal and sued. But he ran for Senate. After being impeached for corruption. This is the guy who spent the nation’s 250th birthday outside the country on vacation with the girlfriend he cheated on his wife (a state senator!) with. And he was videotaped partying in Dubai with fugitives. So he lost, along with every other Republican running for statewide office. It’s unclear whether the new attorney general will drop the case. For now, whether the state can take a tax increase and use it in perpetuity for a project that has ever-increasing capital costs, and then pivot later to use the funds to subsidize operations, remains tied up in the courts. There’s also a citizen lawsuit over the project’s bait and switch. Voters agreed to the taxes for a project that was completely different than the one that the taxes are actually paying for.
