Mobility Authority to Close U-turn at RM 620 in Northwest Austin
U-Turn to Close for Approximately One Year to Accommodate Construction on 183 North Mobility Project
AUSTIN, Texas – Beginning October 10, 2022, Great Hills Constructors (GHC), builders of the 183 North Mobility Project for the Central Texas Regional Mobility Authority (Mobility Authority), will close the U.S. 183 U-turn just south of RM 620, for the U.S. 183 northbound to southbound traffic movement. Drivers traveling northbound and needing to turnaround and travel southbound on U.S. 183 or the frontage road, will be able to turn left at the traffic light at the RM 620 intersection, instead of using the U-turn.
The closure of the U-turn will be continuous, 24 hours a day, seven days a week and will last approximately one year.
The purpose of the closure is to allow construction vehicles and crews access to the center median between the northbound and southbound lanes of U.S. 183 to minimize interference with traffic on the mainlanes, to facilitate the construction of Phase 1 for the project. This access increases safety and reduces the potential for traffic delays from construction vehicle traffic entering and exiting the roadway.
Entrance to the U-turn will be signed as “Construction Traffic Only” with additional signage advising drivers to turn left at the intersection.
*Dates are subject to change based on weather and other circumstances.
More information, including scheduled lane closures, will be updated on the project website: 183North.com.
