What you need to know
The road is part of the Central Texas Regional Mobility Authority’s 183A Phase 3 project, which extends the existing 10-mile 183A Toll northward, according to the Mobility Authority’s website.
The project adds two tolled lanes in each direction within the median of the US 183 corridor and introduces a shared-use path spanning from Hero Way to Seward Junction Loop, according to previous Community Impact reporting.
According to a release from the Mobility Authority, the extended 183A Toll will provide drivers with nearly 16 miles of travel between Liberty Hill and Northwest Austin by bypassing traffic signals at:
- Hero Way
- San Gabriel Parkway
- Bryson Ridge Trail
- Whitewing Drive
"This is a fast-growing corridor in a fast-growing community, so this new stretch of 183A Toll will bring much-needed congestion relief to Williamson County," Mobility Authority Executive Director James Bass said in the release.
Keep in mind
The toll rate for a trip on the roughly 5-mile extension is $2.83 for drivers with electronic tags, like a TollTag or EZ Tag. Drivers wishing to avoid a toll charge can use the nontolled general purpose lanes of US 183, per the release.
In the coming weeks, construction crews will continue working on the final stretch of 183A Toll main lines, which will allow drivers to bypass the signaled intersection at Hwy. 29, according to the release.
Necessary closures for construction will be implemented until the project is complete, and crews will also be finishing construction on:
- Nontolled improvements north of Hwy. 29
- A 7-mile shared use path
- Landscaping and aesthetic installations
The 183A Phase 3 project was financed by the selling of bonds backed by toll revenue and a loan from the U.S. Department of Transportation, Mobility Authority spokesperson Sylvia Shelton previously told Community Impact.

The 5.3-mile 183A Toll’s April 9 opening is subject to change based on weather or outside circumstances, according to the release.
