An 11-mile toll road extending northward from RM 620 through Cedar Park and Leander in Williamson County

Those looking to bypass traffic congestion have a choice to use 183A Toll. Drivers who prefer not to pay a toll can use the non-tolled lanes on US 183 or the 183A frontage roads north of RM 1431.

The Mobility Authority’s first project, 183A Toll, extends 11 miles northward from RM 620 in northwest Austin through Cedar Park and Leander in Williamson County. The project, which consists of tolled mainlanes with non-tolled frontage roads at the north end, has significantly improved travel times and reduced traffic on adjacent roadways, including US 183. Growth along the 183 corridor has continued to drive the need for congestion relief prompting the Mobility Authority to extend 183A farther north to SH 29 with the 183A Phase III Project.

Use Your Electronic Tag or Drive on Through, We’ll Bill You

183A Toll is completely automated with no need to stop or even slow down at toll booths. The choice is yours – utilize the all-electronic, or cashless, tolling method of payment through an electronic tag account; or if you don’t have an electronic tag just keep moving, and we’ll bill you through the Pay By Mail program.

In Texas, there are multiple transportation agencies that are authorized to operate toll roads, issue their own electronic tag, and do their own billing. In the Austin area, there are two: the Texas Department of Transportation (TxDOT/TxTag) and the Central Texas Regional Mobility Authority (Mobility Authority).

Mobility Authority customers can pay their tolls with a TxTAG, TollTag, EZ TAG, K-TAG, Pikepass, SunPass, E-470’s ExpressToll or Bancpass and get a 33% discount, or they can choose to Pay By Mail. Pay By Mail customers are billed using a picture of their license plate, and are charged a $1.00 statement fee per bill. Vehicle registration information must be up to date in order for the bill to be sent to the correct address. Pay By Mail is available on all toll roads in Central Texas, although you may receive separate bills depending on which agency operates the road you traveled on.

Phases I, II, & III

Phase I. A tolled roadway between RM 620 and RM 1431, with non-tolled frontage roads northward from RM 1431 northward to the San Gabriel River. It opened in March 2007.

Phase II. A 5-mile extension northward from RM 1431 to Hero Way. The extension opened in April 2012 and resulted in a significant shift of traffic from the non-tolled frontage roads to the new tolled mainlanes.

Intersection Improvements. Non-tolled operational improvements and enhancements to the US 183/183A (North) intersection were delivered to make the intersection safer and easier to navigate, and to enable better access to developments along 183A. The project entailed pavement widening, drainage improvements, signal adjustments, and minor new road construction of CR 276. It also included access road reconstruction on the west side of the intersection and stub out connection for the future extension of a new road, Bryson Ridge Trail, on the east side of the intersection. The improvements facilitate smoother and safer turning movements and feature a more traditional design for improved access across the southbound lanes. These safety and operational enhancements were made possible through a partnership that included the Texas Department of Transportation (TxDOT), the City of Leander through the Pass Through Program, and an adjacent developer (currently Crescent) opened to traffic in September 2015.

Phase III. This 6.6-mile roadway will extend 183A north from Hero Way to north of SH 29 and have two tolled lanes in each direction with an option to widen to three lanes in the future. The Mobility Authority’s highway will be located within the existing TxDOT right-of-way and within the median of the existing US 183 corridor. Construction is currently underway.

Bicycle & Pedestrian Facilities. 183A Toll Shared Use Path includes a 10-foot-wide, 7-mile long dedicated bicycle and pedestrian path that borders the 183A facility from South Brushy Creek to Hero Way. It also includes a trailhead and pedestrian bridge that crosses Brushy Creek as well as a connection to Williamson County’s Brushy Creek Regional Trail.
