Over the course of construction there will be major activities that will impact the region. As those activities are scheduled, we will keep the community updated.
Traffic Shift on U.S. 183 General Purpose Lanes
Throughout the summer, a gradual traffic shift will occur along both the northbound and southbound US 183 mainlanes to allow crews to focus on work on the outside lanes of the project and open four continuous lanes to traffic in each direction. Each night crews will shift traffic along 3,000-4,000 feet of roadway and open an additional fourth lane to traffic.
The project team will start Segment 1 on the southbound mainlanes at Loop 360 in early June then switch to Segment 2 on the northbound mainlanes. After the northbound mainlanes are complete, the project team will move to Segment 3, the final section from MoPac to Loop 360, towards the end of summer.
A plan is in place to make sure that the shifting of traffic and opening the additional lanes positively impacts the flow of traffic in a safe and organized way, including the use of on-road signage to help guide drivers. Please keep in mind that all construction is dependent on weather and other factors and subject to change. During and after the traffic shift there will still be lane closures and additional work that will happen, particularly on the frontage roads.

Frontage Road Activities
Crews have begun utility relocations, sidewalk reconstruction and related business driveway reconstructions along the corridor. All existing sidewalks along the frontage roads will be updated to be ADA compliant and crews will be adding sidewalks where none exist between SH 45/RM 620 and Loop 360. Currently, there is a long-term closure along the right lane of the southbound MoPac frontage road between US 183 and Steck Ave. that will last approximately nine months and is needed to perform utility relocations, sidewalk and driveway construction. The utility relocations are being implemented first. For more information about our plan to improve the bike and pedestrian facilities along the project corridor go here.
Concrete Batch Plant Operations
The Mobility Authority has concluded initial outreach to businesses near Pecan Park Boulevard and FM 620 regarding the installation and startup of a temporary concrete batch plant. Concrete from the plant will be used to pave new lanes for the 183 North Mobility Project. Once in production, the plant will run primarily at night, as long as road paving is in progress on 183 North. The project’s outreach team has met with area businesses, making them aware of potential sound, dust and light issues at night and how the construction team has and will continue to mitigate those impacts.
In Progress - Miscellaneous Work
Crews have completed or are working to complete several milestones already, including, but not limited to:
- Interior widening – currently complete from Anderson Mill to Balcones Woods
- Outside widening - Portions of outside widening along SB MoPac have also been completed between US 183 and FM-2222
- Outside widening caps and columns – this has been completed along both US 183 northbound and southbound frontage roads

Upcoming Work
In 2024, crews are targeting several major activities, including, but not limited to:
- Construction of up to 15 retaining walls to facilitate outside widening of US 183 general purpose lanes
- Interior widening of bridge decks for Pecan Park, Lake Creek, Anderson Mill, McNeil/Pond Springs, Oak Knoll, Duval, and Balcones Woods, which will be used temporarily to allow construction of an outside lane and ultimately as managed toll lanes
- Various drainage improvements to the frontage roads between RM-620 and Loop 360 to allow for construction of the outside widening along US 183 as well as improved drainage along frontage roads
