Walk the north shore of Lady Bird Lake this month and you will hit orange construction fencing twice. Once near the Austin Rowing Club, where the path narrows around equipment for an underground electrical project. Again farther east, near the I-35 bridge, where a parking lot that used to sit in the shade has been gone for a year and the trail detour around it is built to last most of a decade.
Both look like the same story: more downtown construction, more cones, more reasons to grumble about a trail that never seems finished. They are not the same story. One of these detours ends in about six months. The other has seven more years to go. Knowing which is which changes how you plan a Tuesday morning run, and it says something true about how downtown actually grows: not in one clean finish line, but in overlapping projects that land on different clocks.
The 13 Acres That Just Opened
The reason there's anything new to walk on at all is a project called The Confluence, the second phase of Waterloo Greenway's long rebuild of Waller Creek. It opened to the public on June 6, running from 4th Street down to Lady Bird Lake, and it represents a $91.5 million public-private investment, according to the city's project page for the Confluence. Thirteen acres, reconstructed creek banks, and a landscape planted with roughly 1,600 new trees and 200,000 native plants.
The physical centerpiece is an 800-foot boardwalk built right into Waller Creek, designed specifically so trail users no longer have to stop at street level for the intersections at Red River and Cesar Chavez. Three lattice bridges cross the creek at different points, giving walkers new east-west shortcuts that didn't exist a year ago. New gathering spots came with it: a Lagoon Overlook and Leaf Deck near the lake, a shaded Lakeview Terrace and Explorers Garden, and a Cypress Grove and Trailhead Plaza where the new stretch meets 4th Street.
What makes this section matter more than a typical park expansion is what it connects. The Confluence sits at the point where the Lance Armstrong Bikeway, Palm Park, the Rainey Street Historic District, and the Ann and Roy Butler Hike-and-Bike Trail all meet, alongside the Emma S. Barrientos Mexican American Cultural Center and the Austin Convention Center. It is also the first Waterloo Greenway phase to carry federal dollars, an $11 million commitment from the U.S. Army Corps of Engineers for the project's biofiltration pond, the first infusion of federal money after years of relying on city and private funding alone.
Two Detours, Two Timelines
Here is where the confusion starts. Right at the edge of this new section, near the Austin Rowing Club building, Austin Energy is installing underground electrical infrastructure along the lakeshore between Brazos and Trinity streets. That work began in June 2026 and reroutes a stretch of the Butler Trail's north shore through March 2027, a detour tied directly to finishing the Confluence's utility work.
A few blocks east, near the I-35 bridge, a different agency is running a different project on a different timeline. TxDOT's Capital Express Central expansion took over the free parking area under the north side of the bridge starting in September 2025, staging equipment there through 2033. The Butler Trail detour that followed keeps the loop intact with a temporary path roughly 14 feet wide, but TxDOT is also planning a standalone pedestrian bridge on the east side of the highway crossing, a project that will take years, not months, according to KUT's reporting on the trail detour.
So the honest read on the trail right now is this: the Confluence detour is a short-term inconvenience tied to work that's mostly done. The I-35 detour is a long-term reality tied to a highway project still in its early years. Treating them as the same kind of disruption means writing off a stretch of trail that's actually finished, and underestimating one that genuinely won't feel normal again until the next decade.
The Light Show That Now Costs Money
If you want proof that the Confluence stretch has become somewhere worth going, look at what just moved there. Creek Show, Waterloo Greenway's annual light-art event, has run every fall since 2014, always free, always along whichever section of Waller Creek was open at the time. Last November it skipped a year entirely while the Confluence finished construction.
This November it returns, November 13 through 21, six to ten each evening, and for the first time in its history it's a ticketed event, with proceeds going to the Waterloo Greenway Conservancy. Ten new site-specific installations from local architects and designers will line the new stretch, including:
- Moon Tower 15.1, from HKS Architects and DPR Construction, a disco-ball-like structure that nods to Austin's historic moon towers and sits less than a block from the original Moon Tower 15
- Fractal Time Fish: Portals of the Confluence, by WarrPaint, welded steel sculptures wrapped in dichroic film that shimmer by day and glow under LEDs and lasers after dark
- Waller Wildings, from Kick Punch Bite, LLC, part of the show's recurring theme of imagining the creek's wildlife
A free annual tradition becoming a paid one is not a small shift. It's a sign that the organization behind it believes this new ground can carry an audience large enough, and invested enough, to fund the next phase of work. More on that below, because that next phase is the part of the trail still very much unfinished.
What's Not Finished Yet
Sandwiched between the new Confluence stretch and Waterloo Park sits Sir Swante Palm Neighborhood Park, a 1.8-acre plot at 200 N. IH-35 that has served as a gathering place for Mexican American families for generations. The park grew up around Palm School, which operated for 84 years before closing in 1976. Waterloo Greenway has spent more than a decade collecting community input on how to rebuild it, and portions of the park have served as a staging ground for Confluence construction along the way.
That rebuild has not started. According to reporting from Austin Current, construction is expected to begin in the middle of 2027, with the park reopening in 2029, at a cost of roughly $14 to $15 million. A separate wrinkle has stirred some frustration locally: Waterloo Greenway plans to name ten features of the redesigned park after donors, a fundraising tool built into its agreement with the city, at the same time residents are already frustrated by disruption from the I-35 expansion nearby. Part of Palm Park is also expected to close for up to 700 days while waterlines are rerouted to make room for that highway work.
So the honest map of this quarter mile of downtown right now includes one section that's genuinely done, one detour ending soon, one detour lasting years, and one park that hasn't broken ground yet. Four different states of completion within a few hundred yards of each other.
Reading the Trail This Fall
None of this happens in isolation from what's a few blocks north. Moody Amphitheater's fall calendar is unusually packed this September and October, with Jimmy Eat World, Shaboozey, NEEDTOBREATHE, and Chance The Rapper all playing within the first two weeks of September, followed by MUNA, Dominic Fike, Rise Against, and eventually Jack White and Dermot Kennedy into October. On show nights, expect heavier foot traffic and rideshare pickups concentrated along the north curb of 12th Street just past Red River, spilling south toward the newer Confluence paths as concertgoers find their way to parking and transit.
If your routine includes an evening walk or run through this stretch, checking the amphitheater's schedule before you head out is worth the thirty seconds it takes. If you're out on a non-show night, you'll likely have the new boardwalk and bridges mostly to yourself, at least until Creek Show opens in November and draws its own crowds back to the water.
The larger point is one worth holding onto if you live down here: downtown doesn't finish all at once. It finishes in pieces, on staggered timelines set by different agencies with different budgets, and the only way to actually know what's changed on your regular route is to track which piece you're standing on. Right now, the piece behind Rainey Street is done. The piece past it is not, and won't be for a while.
If you're curious how these changes are shaping property values, foot traffic patterns, or interest in specific downtown blocks, that's exactly the kind of on-the-ground detail The Agency Austin - Noa Levy tracks every week. Let's Connect if you want a read on what any of this means for where you live now.
