Ongoing, long-term travel impacts include the following:
The southbound to northbound u-turn at Hero Way is closed. Drivers may continue to turnaround at the signalized intersection.
Traffic along northbound US 183 has shifted permanently onto new lanes beginning south of CR 258. Two lanes of traffic have been maintained. New traffic signals at the intersection of US 183 and CR 258/CR 213 will cotninue to operate in a temporary flash setting. Drivers on US 183 should be prepared to yield to crossing traffic. View a map here.
The northbound to southbound U-turn south of SH 29 is closed. Drivers are advised to use either turnarounds at Seward Junction Loop or north of SH 29 to access southbound US 183.
The pedestrian crosswalks at the intersection of SH 29 and US 183 are closed. The Project includes pedestrian improvements at this intersection such as the addition of sidewalks and upgraded signalized crossings. View a map here.
*Please note:
Construction activity will occur throughout the entire corridor simultaneously until completion of the project, anticipated in early 2025.
Construction will take place primarily within the existing US 183 median and right-of-way, minimizing impacts to the traveling public. However, the community should remain prepared for:
While construction is an inherently disruptive process, we make every effort to minimize the impacts as much as possible. Mitigation measures on the 183A Phase III Project include:
We do our best to communicate traffic impacts to the public in advance of work through weekly email notices, twitter, and other direct channels. However, shifts in scheduled activities do occur so project traffic impacts are kept up to date on this page.
Reminder: The corridor is an active construction zone. Please do not park or walk within the median or along the sides of the roadway, including the area around the San Gabriel River. Thank you for your cooperation.
View our 183A Phase III Construction Guide for more information on what to expect during construction. For any questions or concerns about construction activities, please reach out to the Project Team directly through our contact form or by phone at (512) 340-1111.
We thank you for your patience as we work as quickly and as safely as possible.
