The 183 North Mobility Project is nearing completion. We've already reached several key milestones in the project, such as adding a fourth non-tolled general purpose lane in the northbound and southbound directions of US 183 in areas where there had previously only been three lanes, completed in August 2024. In addition, early 2026 saw the phased opening of the 183 Express Lanes both northbound and southbound, including the connection between the new express lanes and MoPac through a direct-connector (DC) structure and the collector-distributor road that exits from the DC and serves as a signal bypass along the southbound MoPac frontage roads.
But there is still some work to be done as we put the finishing touches on the 183 North Mobility Project over the remaining months of 2026.
Read more below (this schedule and the activity details are subject to change based on weather or other logistical factors):
- Frontage Roads and Roadside Features:Conventional work along the frontage roads, including grading, landscaping, and sound wall construction, will continue over spring 2026.
- Next Generation Grinding Operations: Final next-generation concrete surface grinding operations are scheduled to take place throughout the spring along all US 183 mainlanes. In order to keep the traveling public moving during peak-traffic periods, this work will require multiple nighttime lane closures, including triple lane closures at times to allow six grinding machines to operate efficiently. Though we do our best to minimize construction noise wherever feasible, these grinding activities are expected to be noisy, but will be transient in nature to any one specific area. Crews will work to move out of each segment as quickly and safely as possible. Several activities will occur concurrently, including installation of final pavement markings. Once complete, the final surface will provide clean pavement with clear lane delineation.
- Asphalt Work: Asphalt paving on MoPac and the US 183 frontage roads is planned to begin in late spring 2026 . These activities represent the final major operations on the US 183 mainlanes and are expected to last several months.
- Sidewalk Work: Sidewalk construction continues along MoPac, as well as in select areas along US 183 with crews working as quickly as possible to make the network of sidewalks along the US 183 frontage roads connected and ADA-compliant.
