Motorists who regularly drive on any portion of the 14-mile corridor known as Loop 360, or the Capital of Texas Hwy., will likely already have guessed it is planted firmly in a list of Texas’ most-congested roadways.

According to a study conducted by the Texas A&M Transportation Institute, the section of the Capital of Texas Hwy. running from RM 2222 to US 183 sees a daily traffic volume of 47,777 vehicles and carries a congestion cost, or value of extra travel time and extra fuel consumed by vehicles traveling at slower speeds, at $15,916,579.

But the traffic problems aren’t just limited to the northernmost segment, and information from the Texas Department of Transportation states the department will be working on solutions to the thoroughfare’s congestion problems heading into 2026. TxDOT’s Loop 360 program will upgrade multiple intersections over the coming months and years in order to improve mobility and safety.

The total cost of the project comes from a 2016 $46 million mobility bond provided by the city of Austin combined with a $204 million investment from TxDOT.

Below is a guide to progress and timelines on each intersection within the Loop 360 project. For much more information from TxDOT on the massive infrastructure project, click here.

Spicewood Springs Road

Timeline: Work began in the summer of 2018. Environmental, preliminary and final engineering stages are anticipated to be complete in late 2022.

Proposed solutions for the intersection: removal of traffic signals from main lanes, construction of overpass at East Spicewood Springs Road and Bluffstone Cove, addition of shared-use path and sidewalk within project limits.



Lakewood Drive

Timeline: The environmental, preliminary and final engineering stages are anticipated to be complete in late 2022.

Proposed solutions for the intersection: removal of the traffic signal from main lanes, construction of overpass or underpass



RM 2222/Courtyard Drive

Timeline: Environmental work began in the summer of 2018. The environmental, preliminary and final engineering stages are anticipated to be complete in mid-2023.

Proposed solutions for the intersection: removal of the traffic signal from the Loop 360 main lanes at Courtyard Drive and construction of an underpass, construction of a diverging diamond intersection at RM 2222 and the addition of a shared-use path and sidewalks



Westlake Drive

Timeline: Work began in the summer of 2018. Environmental, preliminary and final engineering stages are anticipated to be complete in mid-2022.

Proposed solutions for the intersection: removal of the signalized intersection from the main lanes, construction of either an overpass or underpass, and the addition of a shared-use path and sidewalk within the project limits



RM 2244

Timeline: Environmental, preliminary and final engineering is scheduled to be complete mid-2026.

Proposed solution for the intersection: This project consists of improvements to the intersection at RM 2244, including a new diverging diamond intersection, which allows through traffic and left-turning traffic to proceed through the intersection simultaneously, eliminating the need for a left-turn arrow.



Lost Creek Boulevard/Westbank Drive

Timeline: Environmental, preliminary and final engineering is scheduled to be complete early 2026.

Proposed solution for the intersection: improvements to the intersections at Lost Creek Boulevard and Westbank Drive, including removing the signal on the main lanes and adding either an overpass or underpass at each intersection



Walsh Tarlton Lane

Timeline: Environmental, preliminary and final engineering is scheduled to be complete early 2025.

Proposed solution for the intersection: Improvements to the intersection at Walsh Tarlton Lane, including removing the signal on the main lanes and adding either an overpass or underpass
