Here's the latest on three transportation projects in the Lake Travis-Westlake area.

Hamilton Pool Road widening (FM 3238)

The second side of Hamilton Pool Road continues to be widened as of February. Current construction includes a focus on each side of the Vail Divide up to Hwy. 71.

The latest work being completed includes finalizations of paving this summer. Cleanup and road surface markings are scheduled for this fall.

Drivers can expect various night lane closures throughout the progress of completing the project.


Officials broke ground in 2021 on Hamilton Pool Road, also called FM 3238, for their widening roadway project.

The project consisted of a continuous center-turn lane and 6-foot shoulders. A single lane in each direction with a continuous center-turn lane is set to be made.

These modifications “will improve safety, mobility and congestion along this roadway,” said Antonio Luján, public information officer with the Texas Department of Transportation. The $15.8 million project funded by TxDOT is expected to be completed by fall with weather permitting, Luján said.

Loop 360 improvements


Intermittent closures are expected to continue as environmental work proceeds for the Loop 360 road improvement project. Recent updates from the Loop 360 account on X, formerly Twitter, include various closures typically occurring from 8 p.m. to 5 a.m.

Loop 360’s roadway project currently awaits for additional funding to become available before moving forward.

Loop 360 from MoPac to RM 2244 began environmental work in fall 2019. The Loop 360 program schedule expects to begin construction from MoPac to RM 2244 in mid-2025.

Plans for the 14-mile corridor that runs from US 183 on the north end to US 290/Hwy. 71 on the south end include the removal of traffic signals of main lanes in the south entrance of Barton Creek Square, Walsh Tarlton Lane, Westbank Drive, Las Cimas Parkway and Lost Creek Boulevard, as mentioned in the Loop 360 project overview.


The project expects to build an overpass or underpass at Walsh Tarlton Lane, Lost Creek Boulevard and Westbank Drive.

RM 2244’s proposed project solutions mention the addition of a diverging diamond interchange at the intersection, Luján said. Construction of RM 2244 has a target date of mid-2026 for construction to begin. Spicewoods Spring Road also expects to start construction in mid-2025.

Within the limits of the plan, a shared-use path and sidewalks for bicycles and pedestrians are also expected. Construction of continuous one-way northbound and southbound frontage roads is included in the project overview.

Additionally, either an overpass or an underpass at Lost Creek Boulevard and Westbank Drive are being considered, Luján said.


Overlay roadway work from Crystal Mountain Drive to Beardsley Lane

Lone Star Paving completed a TxDOT project in December.

The Texas Department of Transportation completed overlay work from Crystal Mountain Drive to Beardsley Lane.

The modifications included repairing and resurfacing of the roadway. Full depth pavement repair and repavement cost $1.1 million, funded by the TxDOT Preventative Maintenance Budget, Luján said.
