183A ExtensionIn March 2007, the Mobility Authority opened its first project, the 183A toll road in Williamson County. Since then, traffic on 183A has greatly exceeded projections. As a result, the Mobility Authority accelerated development of the northern extension of the roadway in order to meet driver demand and enhance mobility in the corridor. The 183A Extension will be a limited-access toll road with three lanes in each direction. It is being constructed in the median of the existing frontage roads from FM 1431 north of RM 2243. The frontage roads will remain non-tolled. Construction began on the project in March 2010, approximately 7 years earlier than originally planned. More information about the 183A Northern Extension, including maps, schematics, construction updates and the planned 183A shared use path, can be found on our project web site, www.183A.com. Estimated project length: 5 miles, from FM 1431 to north of RM 2243
