Nightly MOPAC CLOSURES for Northbound MoPac:

Beginning Tuesday evening, November 29, 2016, workers will be completely closing northbound State Loop 1 (MoPac) each night after 8:00 p.m. between Lady Bird Lake and Enfield Road. All traffic will be detoured off the Enfield Road exit. Drivers will pass through the Enfield Road intersection before re-entering MoPac. Law enforcement officers will be actively managing the traffic signal at Enfield Road to keep traffic moving. The Cesar Chavez and 6th Street ramp to northbound MoPac will also be closed, with traffic diverted to the Enfield Road onramp. All lanes and ramps should reopen each morning by 5:30 a.m. (Map Attached)

The closure of northbound MoPac is needed to install new asphalt pavement, so MoPac can be restored to three northbound lanes between Lady Bird Lake and Enfield Road. The third lane has been closed since February 2016, when traffic was temporarily realigned to make room for construction of an Express Lane underpass.

Originally, workers intended to perform the paving work the Weekend of December 3rd and 4th, but the threat of cold weather and rain led to an expedited work plan. The goal of the new plan is to ensure the third northbound lane reopens prior to the start of the Trail of Lights on December 10th.

It is expected to take at least four nights of closing MoPac to complete the work necessary to reopen the third lane. Depending on weather conditions overnight closures may be needed the week of December 5th to complete the work.

The closure of northbound MoPac is expected to cause significant travel delays. Drivers are encouraged to avoid northbound MoPac while this work is taking place and to use alternate routes if possible. Full details about the lane and ramp closures can be found at
