Drivers can anticipate a gradual traffic shift this summer as project officials with the US 183 North Mobility Project slowly open a fourth travel lane in each direction.

What’s happening?

From the second week of June throughout the rest of the summer, transportation officials are opening 3,000-4,000 feet of roadway in the newly constructed fourth lane of US 183 North, according to a news release. The project is split into three segments:
  • Segment 1 starts on the southbound main lanes at Loop 360 and gradually moves north.
  • Segment 2 targets the northbound main lanes starting at SH 45 and gradually moves south.
  • Segment 3 will focus on the final southbound section from MoPac north to Loop 360.
Work began with Segment 1 in the second week of June, and will be followed by Segment 2 and Segment 3 in order toward the end of the summer, per the news release.

What to expect

Drivers can expect to gain a lane in the direction they are traveling over time on US 183 North, and there will be on-road signage to help guide drivers, the news release states.

Project officials are working on a plan to ensure the traffic shifts impact the flow of traffic positively and safely, according to the news release.

Ongoing closures will still happen throughout the summer as work continues, with particular focus on frontage roads. Click here to read more on long-term continuous and overnight closures happening on US 183 North this summer.

The background

The US 183 North Mobility Project spans 9 miles of US 183 from SH 45 in the north to MoPac in the south. The project, led by the Central Texas Regional Mobility Authority, broke ground in early 2022 to increase mobility, ease congestion in the area and create more reliable travel times, according to the CTRMA.

Costing $612 million, project completion is still on track for 2026, CTRMA officials confirmed in February. The project will add two express toll lanes on the interior of the road plus one additional nontolled lane in each direction.

What else?

Timely completion of this shift is dependent upon weather and is subject to change, the release states. For the most updated information on road closures, visit the project’s X, formerly Twitter, page.
