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.
In the southbound direction crews have shifted traffic into its final alignment. Final milling of the existing pavement is being completed and the final layer of permeable friction course pavement is expected to be installed starting in mid-June and be completed by early July. Permanent striping, reflective pavement markers and installation of the express lane delineator sticks will follow completion of the final paving. The southbound express lane is not expected to open until the entire southbound project is completed from Parmer Lane to Cesar Chavez Street.
Section 3 - RM 2222 to Enfield Road:
In the northbound direction workers have completed installation of the permanent concrete traffic barrier along the left hand median and are finishing installation of the light poles on the barrier. Paving work on the widened shoulder in front of Westminster Manor and the Post Apartments between 35th Street and 45th Street is nearly complete and the auxiliary lane is expected to reopen in the next few weeks. Milling of the existing asphalt and level up of that pavement is in progress. The final layer of permeable friction course pavement is scheduled for placement this summer followed by installation of the permanent striping, reflective pavement markers and installation of the express lane delineator sticks. Crews 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 this summer.
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 are preparing to install the base asphalt paving at the entrance to the northbound underpass. That work will be followed by installation of concrete traffic barrier along the shoulders. Final permeable friction course paving of the entire underpass area is expected in July. Other miscellaneous clean up and grading work is underway in the area around the underpass.
All construction time frames are subject to change.
