Roadway & Infrastructure Tracker

The Central Texas Regional Mobility Authority finished extending the 183A Toll 6.6 miles north from Hero Way in Leander to just past SH 29 in Liberty Hill, a $260 million project. The extension is now fully open, giving drivers roughly 16 miles of uninterrupted tolled travel between Liberty Hill and northwest Austin — bypassing several signalized intersections that previously slowed the Santa Rita Ranch and Bryson commute in particular.

A separate $612 million CTRMA project is adding tolled express lanes along US 183 North, connecting toward MoPac. Most work happens overnight to limit daytime disruption. The project was expected to wrap in early 2026 — worth confirming current status before assuming it's finished, since large tollway projects routinely slip.

TxDOT is proposing to widen the 13-mile stretch of US 290 from RM 1826 in southwest Austin to Dripping Springs from four lanes to six, eliminate the current signalized intersections, and add frontage roads with bike and pedestrian paths. The stated reason: peak-hour traffic on this corridor is projected to jump 45% by 2045 if nothing changes, and the corridor saw over 1,500 crashes between 2019 and 2022. The plan has drawn real pushback from some Dripping Springs residents over property impacts — TxDOT's own materials note the design could affect roughly 13 homes, 82 businesses, and a church. As of this writing, the project is still in the environmental study and design phase, with no confirmed construction start date. Treat "the highway is being widened" as a multi-year story, not a near-term event.

A more contained piece of the same corridor — upgrading this specific stretch from a four-lane divided highway to six lanes with pedestrian and bicycle accommodations — is further along, with design work underway. This segment sits closer to Belterra and Headwaters than the broader Oak Hill study area.

TxDOT broke ground on this $5.6 billion project through downtown Austin, adding non-tolled managed lanes in each direction from US 290 East to SH 71/Ben White, lowering the mainlanes between Airport Boulevard and Lady Bird Lake, and removing the upper decks. The project's own stated timeline is roughly nine years to completion. For any household weighing a downtown Austin commute against a new-construction purchase south or east of the city, this is a decade of active construction to plan around, not a short-term detour.

This extension gives South Buda a more direct route to I-35, easing what a former Hays County commissioner described as an especially important commute corridor — by his account, roughly 80% of Buda and Kyle residents commute to Austin for work. Already complete and open, this one is worth knowing about specifically because it already happened; older commute-time information for Sunfield and Kissing Tree may not reflect it.

A 1.3-mile, four-lane extension with four roundabouts connecting Bunton Creek Road to Dacy Lane, funded through Kyle's 2022 bond program at a budgeted $42.5 million. As of the most recent reporting, construction was anticipated to begin in early 2026 — if you're evaluating a commute through this part of Kyle, confirm current groundbreaking status with the City of Kyle before assuming it's still just a plan.

Hays County is designing a new roadway extending Yarrington Road from RM 150 to I-35, intended as an alternative route as RM 150 traffic increases — combined design and right-of-way cost across two segments runs roughly $34 million. No construction contract exists yet. Treat this as a real but not-yet-committed project, not a road you'll be driving soon.

A 7-acre, two-phase retail and restaurant project at Kyle Crossing near I-35, anchored by AutoZone and Spec's and targeting a Thanksgiving 2026 opening with 200+ jobs. Signals continued commercial buildout along the I-35/Kyle Crossing corridor near this cluster of communities. A separately-reported Amazon sortation center near Kyle Crossing Business Park could not be confirmed against a dated, credible source as of this writing — we're not publishing that one as fact.

Widens Pflugerville Parkway from two to four lanes with trails and bike lanes between Colorado Sand Drive and Cameron Road, funded via 2018 bonds, addressing congestion on the fast-growing east side near SH 130. Eminent domain proceedings were approved in 2024; no confirmed construction start date has been published. This is still a multi-year story.

A newer phase widening Weiss Lane near East Pflugerville Parkway, including a new bridge over Gilleland Creek, with construction completion expected in 2027. This is a distinct project from an earlier Weiss Lane segment (Wilbarger Creek to Cele Road) that was already completed back in 2019 — don't confuse older "Weiss Lane widened" news with this newer phase.

Segments 5 and 6 of SH 130 opened back in 2012 and operate today under a 50-year private concession agreement. This isn't news — it's already-available infrastructure worth knowing about as a bypass route if you're weighing a Blackhawk commute, not a "coming soon" project.

Proposes one non-tolled managed lane plus one general-purpose lane per direction between SH 29 and RM 1431, with ramp, bridge, and intersection improvements. TxDOT held public input sessions in April 2024 and again in August 2026; no construction date has been published. Treat this as a long-horizon project still in the study phase.

Widens Ronald Reagan Boulevard to a two-lane southbound roadway between SH 29 and FM 3405 — a stretch that directly touches the roads around Rancho Sienna. Underway since 2024, funded by Williamson County's 2019 road bond at a cost of $53 million, with completion targeted for late 2027.

TxDOT is installing raised medians on Hwy 71 between Bee Creek Road and Hamilton Pool Road to reduce crashes, retaining 10 median breaks and adding one at Caprock Summit Drive. Initial work began around September 2025 after the scope was narrowed in May 2025 following pushback from Bee Cave City Council over disruption near Hill Country Galleria. Completion was expected before summer 2026 — given today's date, confirm with TxDOT whether this has already wrapped.

Would widen RM 620 South from four to six lanes with medians and a shared-use path. Design and environmental work has been complete since 2020, but TxDOT states construction remains contingent on funding not yet secured. Note this is a separate corridor north of Hwy 71's junction near Lakeway/Hudson Bend — it shapes the broader Hill Country commute picture but isn't on Sweetwater's immediate doorstep.
