With unprecedented growth in Williamson County, most notably in Cedar Park, Leander, and Liberty Hill, traffic volumes along US 183 are anticipated to increase by 183 percent over the next 25 years driving the need for proactive congestion relief.

Proposed Improvements

The Central Texas Regional Mobility Authority (CTRMA), in cooperation with TxDOT, is proposing to extend the six-lane, controlled-access, grade-separated 183A tolled main lanes from their current terminus approximately 0.4 mile north of Hero Way to approximately 0.4 mile north of SH 29. The existing US 183 four-lane divided roadway within the proposed project limits would serve as the US 183 frontage roads north to SH 29, and transition back to the existing, undivided US 183 approximately 1.1 miles north of SH 29.

The 6.6-mile proposed tollway project will add two tolled lanes in each direction with an option to widen to three lanes in the future. The proposed tollway is planned to be located mostly in the existing right-of-way (ROW) within the median of the US 183 corridor, where the existing lanes will remain as non-tolled frontage roads. The extension will also feature a shared use path north from Hero Way to the proposed Seward Junction Loop project located just north of the existing Mourning Dove Lane.

With the increase in population and planned transportation improvements, the corridor is expected to attract residential and commercial development resulting in economic growth for the community. Average daily projections show that growth is expected to more than triple by 2030. The extension of 183A Phase III will satisfy the additional demand for capacity and avoid future traffic congestion.

Texas has been aggressively acquiring private land through condemnation for transportation projects across the state to accommodate the needs of a growing population. If you have been contacted by TxDOT or any of their representatives, please contact us immediately. The important thing to remember is that even if you’ve received a letter in the mail from a condemnation entity informing you of their intentions, this does not mean that it’s a done deal. There are many ways to influence the condemnation process to ensure that your wants and needs are met, but it’s important that you involve knowledgeable professionals that can help guide you through the process.
