Problem
Severe traffic congestion– Mobility and safety concerns– Loop 360 is ranked on Texas’ 2018 Most Congested
Roadways list– Currently takes approximately 70% longer to travel during
peak periods than during free-flow conditions– Traffic will worsen as population grows – population is
expected to double by 2040

About the Loop 360 Program
Program purpose: Upgrade multiple intersections to improve mobility and safety along the corridor– Eliminate at-grade crossings – Install over/underpasses at major intersections– Reconfigure RM 2222 and RM 2244 to diverging
diamond intersections– Separate local and through traffic at intersections– Increase safe access to/from adjoining neighborhoods– Add accommodations for bicyclists and pedestrians

Multi-step process with ongoing stakeholder engagement

Lakewood Drive/Spicewood Springs Road
12
Project Overview:
– Remove the traffic signals from the Loop 360 mainlanes at Spicewood Springs Road (E)/Bluffstone Drive, Spicewood Springs Road (W), and Lakewood Drive
– Construct overpasses at Spicewood Springs Road (E)/Bluffstone Drive and Lakewood Drive with non-signalized U-turns in both directions
– Add a shared-use path and sidewalks within the project limits
Due to their proximity and similar environmental considerations, TxDOT has combined the environmental process for the Lakewood Drive and the Spicewood Springs Road projects
Environmental stages complete: early 2021

Project Overview:– Remove traffic signal from the Loop 360 mainlanes at
Courtyard Drive and construct an underpass – Reconfigure RM 2222 at Loop 360 to a diverging
diamond intersection– Add a shared-use path and sidewalks within the
project limits Environmental, preliminary and final engineering
complete: mid 2023

RM 2244:
– This project is the last scheduled project in the program and has not yet moved forward into the environmental stage. It is likely that RM 2244 at Loop 360 will be reconfigured to a diverging diamond intersection
– Environmental, preliminary and final engineering complete: mid 2026
Westbank Drive/Lost Creek Boulevard:
– This project is still in developmental stages. It is likely that the traffic signals will be removed at both intersections and either overpasses or underpasses will be installed
– Environmental, preliminary and final engineering complete: early 2026

Context Sensitive Solutions (CSS)
25
A collaborative approach to developing roadways that fit within their surroundings
Considers not only physical aspects or standard specifications of a roadway, but also community resources
Community Feedback
– November 2018: TxDOT conducted a survey to receive feedback from the community
– March 2019: TxDOT shared the results of that survey and collected further public input
– June 2019 and August 2019: TxDOT collected and incorporated additional feedback on the refined options
