Drive the frontage road along SH 71 past Oak Hill Plaza this week and something feels different. The overhead signage TxDOT installed near Scenic Brook Drive over the past year finally has traffic flowing beneath it the way it was designed to. But turn onto Convict Hill Road, and you're still looking at a right-in, right-out only intersection that was supposed to be temporary back in July. That gap between "the project is done" and "my corner of the project is done" is the actual story for anyone living in Barton Creek West this fall.
Community Impact reported on September 9 that the Texas Department of Transportation has completed almost all of the work on Oak Hill Parkway after four years of construction. That's the headline. It's also the version of this story every commuter group and neighborhood Facebook thread has already shared. What those posts skip is that "substantial completion" on a seven-mile corridor doesn't arrive everywhere at once. It arrives intersection by intersection, and which one you use on a normal Tuesday still determines whether your week feels easier or exactly the same as it did in June.
The Milestone That Just Landed
Some context on why this took as long as it did. The Oak Hill Parkway project had been in planning and development for over three decades before TxDOT broke ground in 2021, converting the four-lane, undivided stretch of US 290 and SH 71 into a six-lane divided highway with new frontage roads and 14 miles of shared-use paths. The price tag landed at $677 million. Contractor Colorado River Constructors, a joint venture of Fluor and Balfour Beatty, handled the build, with AECOM as lead designer.
The scale of the dirt work alone explains some of the delay. TxDOT's project manager noted that crews removed more than 2 million cubic yards of material to lower the roadway beneath the new bypass, enough to fill over 600 Olympic-sized swimming pools. Community input, funneled through groups like the Oak Hill Association of Neighborhoods, also shaped the final design, including a realignment meant to preserve large oak trees the community wanted to keep.
The reason this corridor mattered enough to fight over for thirty years: average daily traffic here is projected to top 152,000 vehicles by 2040. This wasn't a cosmetic fix. It was a rebuild sized for a corridor the Texas A&M Transportation Institute has ranked among the state's most congested roadways.
Same Corridor, Different Experience Depending on Where You Turn
Here's where the nuance actually lives. TxDOT's own construction updates show a corridor that improved in patches, not all at once, and some of those patches were still mid-transition as recently as this summer.
| Access Point | What Happened This Year | Status as Substantial Completion Arrives |
|---|---|---|
| Oak Hill Plaza / Center of the Hills (SH 71) | Cross-street access between the two shopping centers closed in January 2026 for bypass bridge work, forcing right-in, right-out movements and U-turns at Scenic Brook Drive or near the Tesla store | TxDOT's own documentation said this configuration would hold only until project completion, which just arrived, so full turning movements should be returning now |
| Convict Hill Road | Direct cross-street access closed in early July 2026, with westbound US 290 drivers detoured to U-turn at RM 1826 | Tied to finishing the corridor's last remaining bridge, one of the final pieces on TxDOT's punch list |
| Fletcher Lane (westbound SH 71) | Reduced to a single lane through the summer months, according to TxDOT | Summer is over and substantial completion has landed, so this stretch is due for its second lane back |
None of this shows up in the "project is finished" headlines, and that's exactly the gap a resident feels. If your route runs through Convict Hill, your fall might still involve a detour. If it runs past Oak Hill Plaza, you may already be back to normal turns.
What This Means for a Trip to Lantana Place
For a lot of Barton Creek West households, the real test of this project isn't the commute downtown. It's the Saturday run to Lantana Place, the mixed-use development on Southwest Parkway immediately south of the Barton Creek community.
Lantana Place's tenant list reads like a shorthand for the neighborhood's routine: CARVE American Grille, the live-fire sibling to Perry's Steakhouse, La Popular for contemporary Mexican and one of the busier happy hours in southwest Austin, and La Traviata, the Italian kitchen that moved from its original downtown space into a larger spot here with more parking and outdoor seating. Tancho, the omakase counter that won Austin's Best New Restaurant in 2025, sits in the same retail row alongside Marigold Market, Black Rock Coffee, and Orangetheory Fitness.
None of that changed. What changed is how you get there. The redesigned interchange at the Y and the new flyovers between US 290 and SH 71 mean the drive from most of Barton Creek West to Southwest Parkway no longer routes through the signal-heavy tangle that's defined this intersection for years. That's a meaningful shift for a neighborhood where a dinner reservation at La Traviata used to mean budgeting extra time for the light at the Y.
The Businesses Already Adjusting
The unevenness of this rollout has been visible in how individual businesses along the corridor have talked about it, and the timeline matters here too.
Back in the summer of 2025, when the project had only just passed its halfway mark, a staff member at Oak Hill Social described a new bridge that opened directly in front of the restaurant, giving customers a straight crossing over the highway where none had existed before. That single piece of infrastructure landed more than a year before the rest of the corridor caught up, which is part of why this project has felt uneven to people who drive it daily. Some businesses got their relief early. Others waited.
Once Upon A Child, a children's resale shop that's operated inside the construction zone for the better part of five years, was still describing the experience as a work in progress as of this June. The shop's owners, Karly and Jim English, told KXAN that business had grown with each traffic milestone, and that they'd spent years leaning on social media just to keep customers informed about which entrances were open on a given week. Karly English put it simply: they were "excited to have it finished."
That comment came three months before substantial completion actually landed. It's worth sitting with, because it captures something the finished-headline version of this story misses: for the businesses living inside this corridor, "done" wasn't a single day. It was a string of smaller wins that finally added up.
What's Actually Left to Finish
Substantial completion isn't the same as every cone being gone. TxDOT's own documentation notes that punch-list items, final paving layers, lane striping, and traffic signal installation continue through the fall even after a corridor reaches this milestone. If you're planning a route through Convict Hill Road or past Oak Hill Plaza on a tight schedule this month, TxDOT's project page is the place to check current configurations before you rely on a shortcut that might still be in transition.
The bigger picture is still worth holding onto. A project that took three decades to plan and four years to build just crossed its main finish line. For a neighborhood that's spent years working around cones, detours, and right-in right-out signage, that's not a small thing, even if it didn't arrive at every corner on the same Tuesday.
