The 183A Phase III Project to extend the 183A Toll Road, foresees the adding of two tolled lanes for 6.6 miles in either direction from Hero Way to north of SH 29. It will also build a shared use path from Hero Way to the proposed Seward Junction. The extension of 183A will include the construction of 17 bridges, two of which over the South Fork San Gabriel River.

With unprecedented growth in Williamson County, especially in Cedar Park, Leander and Liberty Hill, traffic volumes along the 183 are seen increasing by 183% during the next 25 years. The project will help alleviate future congestion and reduce driving times for commuters.
