183A is an 11.6-mile toll road operated by the Central Texas Regional Mobility Authority. It extends from northwest Austin through Cedar Park and Leander in northwest Williamson County.
The first section of 183A opened in March 2007. It included a limited-access expressway between RM 620 and New Hope Road and frontage roads from RM 1431 north to the South San Gabriel River. Initial traffic was much higher than originally projected, allowing the Mobility Authority to expedite a 5-mile extension of the expressway from New Hope Road north to San Gabriel Parkway. On April 6, 2012, the 183A Northern Extension opened to traffic.
