*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.
