About the project

The 183 North Mobility Project was first launched in 2013 by the Central Texas Regional Mobility Authority and Texas Department of Transportation.


The $612 million project aims to relieve congestion along 183 North—the 9-mile section of road between MoPac and SH 45—by adding two toll lanes in each direction that will connect to the existing tolls on MoPac and 183A in Cedar Park.

The project also added a fourth nontolled northbound and southbound lane, which opened last year, and is working to improve shared-use paths along the corridor for bikes and pedestrians.

The Mobility Authority is leading the project, in partnership with CapMetro, the Capital Area Metropolitan Planning Organization, and Travis and Williamson counties. Funding comes from TxDOT, a federal loan and toll revenue bonds.
