The Central Texas Regional Mobility Authority, the agency responsible for building and managing toll fares on many of the express lanes in the Austin area, has announced the closure of the Far West Boulevard exit on southbound MoPac beginning July 20 as work progresses on the 183 North Mobility Project.

What you should know

This work is part of the last phase of construction closures in this area as the highway project nears completion in 2026.

The exit will remain closed for the next year. Crews will work as quickly and safely as possible to reopen on time or ahead of schedule, the agency stated in a news release. Construction is dependent on weather, as well as a variety of other logistical factors, the release states.

Detour routes and alternate exits are available, with on-road signage present to help guide drivers.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.

In partnership with CapMetro, the Capital Area Metropolitan Planning Organization, and Travis and Williamson county governments, the project is being funded through TxDOT, a federal loan and toll revenue bonds.
