AUSTIN, Texas — More improvements are on the way for US 183 North in Austin.
The Central Texas Regional Mobility Authority (Mobility Authority) plans to start construction on its 9-mile, $612 million project on the roadway early next year. The project will add two tolled lanes and one non-tolled lane from the MoPac Expressway to State Highway 45 in both directions, among other things.
The Mobility Authority said while construction may occur 24 hours a day, seven days a week, the contractor will face fees imposed by the Mobility Authority if a lane closure occurs outside of approved time frames, such as peak travel times like morning and afternoon rush hours. The Mobility Authority said in order to minimize noise, the project team will follow a set of guidelines designed to preserve the quality of life for nearby neighborhoods.
The Mobility Authority said its intention is for the majority of traffic-impacting construction activities to occur during these off-peak times, whenever possible:
- Sunday morning: midnight to 8 a.m.
- Sunday evening: 9 p.m. to midnight
- Monday-Friday morning: midnight to 5 a.m.
- Monday-Friday evening: 9 p.m. to midnight
- Saturday morning: midnight to 8 a.m.
- Saturday evening: 9 p.m. to midnight
The Mobility Authority said in most cases, daytime work will be focused on construction activities outside the immediate roadway. However frontage road lane reductions may occur for extended periods of time to allow crews to construct the non-tolled general-purpose lanes.
The Mobility Authority said in most circumstances, construction occurring on holidays or during special local events will be limited to activities that don't impact traffic. Lane closures on major holidays or during local events will be avoided when possible and will require special permission by the Mobility Authority and the Texas Department of Transportation.
Construction on the US 183 North project is expected to be completed in 2026.
