Major Activity

New Lane, Open Early Frontage Road Activities Concrete Batch Plant Operations In Progress - Miscellaneous Work Continuous Lane Closures Upcoming Work

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.

New Travel Lane Open on US 183 General Purpose Lanes

Just in time for back-to-school travel, the Central Texas Regional Mobility Authority (Mobility Authority) delivered the early opening of an additional non-tolled travel lane in both directions on the 183 North Mobility Project corridor between State Highway 45 North and Loop 1 (MoPac). This accomplishment brings the total number of non-tolled lanes to four in each direction, up from three previously and means smoother, more reliable travel for drivers as construction continues. While final lane placement will ultimately shift with full project completion in 2026, the increase in the number of non-tolled lanes on US 183 is a permanent condition.

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
