Austin Mayor Proposes $49.8M Plan for Complete I-35 Park Deck

by ethan.brook News Editor

Austin Mayor Kirk Watson is pivoting the city’s ambitious strategy to reconnect neighborhoods divided by Interstate 35, proposing a streamlined plan that prioritizes one fully completed park over several unfinished structural foundations. In a memo sent Thursday to the City Council, Watson suggested a scaled-back approach to the Austin I-35 cap-and-stitch park plan, focusing resources on a single, functional land bridge rather than spending significantly more to install support columns for multiple projects that the city cannot currently afford to finish.

The updated proposal asks the city to fund one complete park deck for $49.8 million. This represents a tactical shift from a previous commitment to pay for the columns of three large decks and two smaller pedestrian “stitches.” While those columns would have allowed for future expansion, officials admitted there were no immediate plans or budget allocations to actually build the decks atop them. Watson’s new direction seeks to provide a tangible public asset that residents can use immediately upon the completion of the broader highway project.

The Austin City Council is scheduled to consider the updated proposal on May 28. The move comes as the city grapples with a looming budget crisis and the reality of a project that has been repeatedly downsized from its original, multi-billion-dollar vision.

A Land Bridge for Palm Park

The centerpiece of the revised plan is the creation of a 160-foot-wide cap over the interstate at Palm Park. Located at the intersection of I-35 and East Third Street, the project is designed to create a “complete land bridge from the park to the East side,” according to Watson. This specific location is already a focal point of urban renewal, as We see currently undergoing revitalization as part of the larger Waterloo Greenway project, an effort to transform the corridor along Waller Creek into a series of parks and trails.

By focusing on Palm Park, the city aims to create a seamless connection between the downtown core and the historically marginalized communities to the east. Watson emphasized the urgency of the project in his memo, stating, “I would like for us to have something that folks can enjoy now.” He argued that selecting an option that can be fully built ensures the community will have a deck plaza ready at the completion of the I-35 CapEx project, while maintaining “long-term fiscal stewardship to the citizens of Austin.”

The “cap-and-stitch” concept refers to the engineering of “caps” (wide lids that create parks or plazas) and “stitches” (narrower pedestrian bridges) that span the highway. For decades, I-35 has functioned as a physical and social barrier in Austin; these structures are intended to mitigate that division by restoring pedestrian flow and green space.

Financing the Pivot

The financial architecture of the $49.8 million proposal relies on a combination of low-interest debt and municipal bonds. Watson detailed that funding would be sourced from a previously approved $41 million low-interest loan provided by the Texas Department of Transportation (TxDOT), supplemented by $8.8 million in city bonds.

A critical component of the timing is the repayment schedule. The first payment on the loan would not be due until at least 2028. According to the mayor, this delay is strategic, as it preserves the city’s debt capacity during ongoing discussions regarding a future bond election.

This fiscal caution is a response to a series of financial setbacks. The program was originally envisioned as a massive undertaking featuring six caps and two stitches with an estimated cost of $1.4 billion. However, the project suffered a major blow last year when a $105 million federal grant, which would have funded a significant portion of one of the caps, was rescinded.

Project Version Scope Estimated Cost / Funding
Original Vision 6 Caps, 2 Stitches $1.4 Billion
Previous Proposal Columns for 3 Decks, 2 Stitches Unspecified (Higher than $49.8M)
Watson’s New Proposal 1 Complete Park Deck (Palm Park) $49.8 Million

Engineering Constraints and Future Growth

Despite the downsizing, the proposal still includes a nod toward future expansion. Watson’s plan calls for the installation of supports for a potential future cap between 11th and 12th streets. While the city does not currently have the funds to complete a deck at that location, the supports must be installed now.

This is a matter of engineering necessity: because TxDOT must account for the precise width and placement of supports during the lowering and expansion of the highway, these columns must be built alongside the road during the primary construction phase. They cannot be added later without disrupting the entire highway infrastructure. Watson suggested that having these supports in place could serve as a catalyst for future private fundraising efforts to complete the deck.

The broader context of this work is the I-35 Capital Express (CapEx) project, a massive overhaul of the corridor. As TxDOT lowers the highway in certain sections, it creates the vertical space necessary for these caps to be installed without requiring massive, unsightly ramps.

Political Shift and Community Impact

The “cap-and-stitch” project has long been a point of contention within the City Council, reflecting a tension between urban idealism and fiscal reality. While there was general agreement on the goal of reconnecting the city, members were deeply split on the scale of the investment amid a looming budget crisis.

The scaled-back proposal appears to have bridged some of that political divide. Council members Mike Siegel and Krista Laine, both of whom expressed hesitation last year due to the project’s high costs, endorsed Watson’s $49.8 million plan on Thursday. Their support suggests that a “quality over quantity” approach—delivering one finished park rather than several skeletal foundations—is more palatable to the council’s fiscally conservative wing.

For the residents of East Austin, the project is more than an engineering feat; it is a symbolic and practical effort to undo the damage of mid-century urban planning. “For too long, I-35 has been a sign of division throughout our city,” Watson wrote, “and this presents an opportunity to ensure that we are not waiting for another few decades to better connect our city.”

The next step for the proposal will be the City Council meeting on May 28, where members will debate whether to move forward with the funding for the Palm Park land bridge and the strategic supports for the 11th and 12th street corridor.
