Section 1 & 2A - US 183 to Parmer Lane:  

The northbound Express Lane opened on October 15, 2016 between RM 2222 and Parmer Lane. Construction is essentially complete in this area with some landscaping work still to be completed. A portion of the shared use path between Braker Lane and Shoal Creek at US 183 still needs to be built. A separate contract is being issued for that work. Construction is expected to begin in late 2017.     

Section 2B - US 183 to RM 2222:

The northbound section of this stretch is complete and the Express Lane is open. Some landscaping work remains to be completed.

On southbound MoPac, the final layer of permeable friction course pavement is down. Crews are in the process of installing permanent striping, reflective pavement markers and delineator sticks to separate the Express Lane from the regular traffic.

The section of the southbound Express Lane between Parmer Lane and RM 2222 will not open until the entire southbound Express Lane is finished all the way down to Cesar Chavez  Street. Opening the northern section early would be of little benefit, since significant traffic congestion occurs between RM 2222 and 45th Street. This congestion could lead to backups that extend north of RM 2222 into the express lane, causing operational issues and frustrating drivers who paid to use the lane. Opening is targeted for late October or early November 2017.

Section 3 - RM 2222 to Enfield Road:

In the northbound direction level up paving should be complete in late August and permeable friction course pavement installation will begin. Installation of the permanent striping, reflective pavement markers and the express lane delineator posts should take place in late September.  The auxiliary exit lane between 35th Street and 45th Street has been reopened and workers are begin to shift all of the regular lanes to the right to make room for the new Express Lane. Widening of the 35th Street exit ramp has been completed and work to wide the 45th Street exit ramp is nearing completion. The northbound Express Lane is expected to open in late September or early October of 2017.

On southbound MoPac workers have completed installation of the concrete barrier and highway lighting along the center median. They are wrapping up work on curbing, sound wall foundations, and concrete slopes along the right hand shoulder. The existing pavement is in the process of being removed and some new pavement has started going down. It will take several weeks to complete the level up paving. After that, sometime in late September, crews will begin placing the final layer of permeable friction course asphalt. The southbound Express Lane is expected to open in late October or early November of 2017, depending on weather.

Workers continue upgrading sidewalks and crosswalks at 45th Street, 35th Street, Westover Road, Windsor Road and Enfield Road, as well as along Newfield Lane and Winsted Lane. They have also begun installing planter beds and other aesthetic upgrades at the various cross streets. Much of that work has been put on hold so crews can focus on other activities aimed at getting the Express Lanes open.

Section 4 - Enfield Road to Cesar Chavez Street: 

The southbound express lane underpass into downtown Austin is essentially complete. Crews will be placing the final layer of permeable friction course pavement around the underpass in September and they are installing a fire protection system and sensors to detect flooding, should it occur. Other miscellaneous clean up and grading work is underway in the area around the underpass. 

Crews have completed construction of the northbound underpass and have been doing miscellaneous clean up and grading work as well as painting. Paving crews have begun laying permeable friction course asphalt around the entrance and exit of the underpass. Installation of a fire protection system and flood detection sensors is underway. 

The remaining overhead signs are currently being installed. All of them should be in place by the first week of September.

 All construction time frames are subject to change.
