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 being laid and should be completed by July 10th. Permanent striping, reflective pavement markers and installation of the express lane delineator sticks will follow completion of the final paving.

The section of 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. 

Section 3 - RM 2222 to Enfield Road:

In the northbound direction workers are current laying new base asphalt and performing level up of the pavement. The final layer of permeable friction course pavement is scheduled for placement in August, followed by installation of the permanent striping, reflective pavement markers and installation of the express lane delineator sticks.  Crews are wrapping up work on concrete traffic barriers between 35th Street and 45th Street and are installing the last of the highway lighting. They are also working to widen the 35th Street and 45th Street exit ramps to allow for two lanes of traffic.

On southbound MoPac workers are installing roadway base material for the widened roadway on the right shoulder of the highway between RM 2222 and Enfield and have begun installing concrete curbs and preparing to install concrete traffic barriers where needed. Temporary concrete traffic barrier is being placed along the left hand median and workers are installing conduit for the highway lighting and concrete foundations for the new concrete traffic barrier. Milling and paving of this stretch is currently scheduled to begin sometime in August.

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. That work is scheduled for completion in August.

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 July. Other miscellaneous clean up and grading work is underway in the area around the underpass. 

Crews have completed construction of the underpass and have been doing miscellaneous clean up and grading work as well as painting. Paving crews are expected to place the final layer of permeable friction course pavement around the underpass sometime in August. 

Additional overhead signage is expected to go up at various locations over the next two months.

 All construction time frames are subject to change.
