Long-Term Travel Impacts & Major Activity

Ongoing, long-term travel impacts include the following:

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:

  • All closures are subject to change based on weather and other circumstances. 
  • These closures are required for construction of the 183A Phase III Project. The traveling public may experience additional closures along the corridor as a result of other neighboring construction projects and are not associated with the 183A Phase III Project.

 

What to Expect during Project Construction

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:

  • Travel delays
  • Lane shifts, closures and detours
  • An increase in noise, vibration, dust and lighting, including during night work
  • The use of trucks and heavy machinery

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:

  • Regular use of water trucks to reduce dust
  • Weekly roadway sweeping to reduce debris
  • Directing construction lights away from residential areas
  • Financial penalties for the contractor if a closure occurs or lingers outside of approved time frames

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.
