The Central Texas Regional Mobility Authority is set to open the southbound 183 Express Lanes on Saturday, Feb. 28, 2026 as a part of the 183 North Mobility Project.
“The opening of the express lanes on U.S. 183 began in a phased approach in early January in the northbound direction. We are pleased to share that Phases I and II of the 183 North Mobility Project have been successfully completed, and we are now preparing to move into Phase III of the opening,” said James Bass, executive director for the Mobility Authority. “This final phase will complete the rollout of the new 183 Express Lanes and further improve corridor connectivity and travel reliability for Central Texans.”.
The express lanes will operate using variable toll pricing, similar to the pricing on the MoPac Express Lanes. The price drivers see on the signs before entering the express lanes is the price they will pay.
Drivers exiting the 183 Express Lanes have several options when traveling southbound:
- Stay in the right lane to continue southbound until the 183 Express Lanes merge into U.S. 183 to access Burnet Road, Payton Gin Road, Lamar Boulevard and Interstate 35.
- Stay in the left lane to access the direct connector to MoPac, which provides access to the MoPac Express Lane and the southbound collector-distributor (CD) road.
- To access the southbound MoPac Express Lane, drivers should stay in the left lane of the direct connector.
- Drivers on the direct connector will exit to the right to enter the collector-distributor road between the MoPac mainlanes and the MoPac frontage road. Drivers on the collector-distributor can bypass traffic lights at Steck Avenue and Spicewood Springs Road, similar to the Steck Bypass along northbound MoPac. The collector-distributor road will merge onto the southbound MoPac frontage road just south of the Spicewood Springs overpass. Drivers will then be able to continue on MoPac frontage road or enter the MoPac general purpose lanes via the ramp just north of Far West Blvd.
