REALTOR® · Published · Updated How do Project Connect and the I-35 Capital Express affect downtown Austin TX real estate? Project Connect is Austin’s voter-approved light rail and transit expansion program. In particular, downtown stations are planned along the Orange and Blue lines. The I-35 Capital Express Central project is lowering I-35’s main lanes between Lady Bird Lake and Airport Boulevard. As a result, the ‘cap and stitch’ approach could create up to 25 acres of new public space in central Austin. Both projects are multi-year commitments in various stages of planning and construction as of 2026. For downtown condo buyers, Project Connect’s downtown stations are a long-term walkability multiplier. Meanwhile, the I-35 cap-and-stitch project could transform downtown’s eastern edge.
Historically, transit access and highway reconfiguration are the two infrastructure decisions that most durably affect urban real estate values over the long term. Understanding where both projects stand in 2026 is essential context for any downtown Austin condo purchase decision. Here is the current status of both projects and their real estate implications. Project Connect — current status and downtown implicationsProject Connect is Austin’s light rail and transit expansion, approved by voters in November 2020. The program includes the Orange Line (north-south), Blue Line (east-west), and the Green Line (commuter rail). As of 2026, the program is in various stages of federal environmental review, design, and local planning. Downtown stations are planned but construction timelines have been subject to ongoing refinement. For condo buyers, proximity to planned light rail stations represents a long-term walkability multiplier — but buyers should evaluate current transit access rather than planned future access when making near-term decisions. Rail-adjacent property premiums typically emerge closest to construction completion. I-35 Capital Express — the cap and stitch opportunityIn addition, the I-35 Capital Express Central project is lowering I-35’s main lanes between Lady Bird Lake and Airport Boulevard as part of TxDOT’s highway widening. The Downtown Austin Alliance’s Our Future 35 initiative aims to make the most of this cap-and-stitch opportunity. For example, it could build up to 25 acres of new public space over the lowered lanes, connecting downtown’s east and west sides. This would be a transformational change to downtown’s eastern edge, improving the connection between downtown and East Austin. As of 2026, construction on I-35 is underway. The cap-and-stitch public space development is in planning. What it means for condo buyers in 2026Both projects — Project Connect and the I-35 cap — represent long-term improvements to downtown Austin’s urban quality that are not yet fully reflected in current property values. Buyers who purchase downtown condos in 2026 with a 7–10 year hold horizon are purchasing before either project’s completion. The specific impact on any given condo building depends on proximity to planned rail stations and the I-35 eastern edge. Therefore, buildings on the eastern side of downtown near the I-35 corridor have the most direct long-term exposure to the cap-and-stitch upside. Frequently asked questionsProject Connect and the I-35 Capital Express are the two infrastructure decisions that will shape downtown Austin’s urban form for decades. Neither is complete — but both are committed and advancing. Buyers who purchase downtown condos in 2026 with a long-term hold horizon are purchasing before either transformation is complete, with upside exposure to infrastructure improvements that typically support urban property values durably over time. For current figures, see the Unlock MLS September 2026 housing report, which put the Austin median near $571K. In downtown Austin TX, Project Connect and the I-35 cap are not just infrastructure projects — they are the long-term case for buying downtown before the city’s urban form is fully transformed. |
