The 183 North Mobility Project is nearly complete with the opening of new southbound express lanes and a flyover direct connection to MoPac on Feb. 28.
Stay in the right lane to keep going south on US 183. This will take you to Burnet Road, Payton Gin Road, Lamar Boulevard and I‑35.
Stay in the left lane if you want to go straight onto MoPac via the express lanes and the special merge lane.
On the flyover to MoPac, stay left to continue on the southbound MoPac Express Lane.
Exit right on the flyover to use the side road that runs between MoPac’s main lanes and frontage road. This lets you avoid traffic lights at Steck Avenue and Spicewood Springs Road.
The side road will merge back onto MoPac’s southbound frontage road just past the Spicewood Springs overpass. From there, you can either keep going on the frontage road or get onto MoPac’s regular lanes via the ramp north of Far West Boulevard.
Mobility Authority officials also said the express lanes will operate using variable toll pricing, similar to the MoPac Express Lane, and that the price drivers see on the signs before entering the express lanes is the price they will pay.

Looking back
The northbound express lanes between Burnet Road and SH 45 North opened Jan. 2. The northbound direct connector, which connects the highway to the express lanes, opened Jan. 31 and spans from the MoPac express lane to the 183 express lanes.
Project background
The $612 million project broke ground in January 2022 and is being funded by the sale of toll revenue bonds and federal funding through the Transportation Infrastructure Finance and Innovation Act program.
According to the Mobility Authority, by 2035 drivers could see nine‑minute trips using the toll lanes, morning commutes on the regular lanes cut by 24 minutes, and evening commutes on the regular lanes shortened by 16 minutes.
Part of the project's construction included an additional general-purpose lane bringing the number of nontolled lanes to four in each direction, which was completed in August 2024.
The completed project will also feature 4,200 feet of shared-use paths connecting bike lanes and 11 miles of Americans with Disabilities Act-compliant sidewalks.
What's next
Mobility Authority Director James Bass said the agency is moving into the project’s final phase, with crews wrapping up connections, adding finishing touches and landscaping the area. There will still be some lane closures as part of the ongoing work; however, the project is expected to reach total completion this year.
