Weekend Lane Closures on MoPac


As part of an all-out effort to complete asphalt resurfacing of MoPac before the summer paving season ends, southbound MoPac will be reduced to just one lane the weekend of August 11th to 14th. The lane closures on southbound MoPac between RM 2222 and Enfield Road will begin at 10:00 p.m. on Friday evening, August 11th and end no later than 5:00 a.m. on Monday morning, August 14th.
Throughout the weekend, the center and left lane will be closed. Only the right lane and the far right auxiliary exit lanes will be open. Law enforcement officers will be actively directing traffic and managing traffic signals at each intersection in an effort to expedite travel. Despite these efforts, significant travel delays are likely. Drivers are urged to avoid southbound MoPac during these closures.
The lane closures on southbound MoPac are needed so workers can begin the process of removing old asphalt and replacing it with new asphalt. The final layer of asphalt that needs to be installed is called permeable friction course (PFC). It provides significant benefits during rain events by reducing the spray coming off cars and trucks and improving visibility. It also provides environmental benefits, by trapping oil and debris that might otherwise get into local waterways. Plus, it is a much quieter surface, which benefits adjacent residents.
However, PFC asphalt can only be laid when roadway surface temperatures are 70 degrees or higher. In order to install the PFC before the summer paving season ends, a number of weekend lane closures may be needed. These closures will also help reduce the amount of time drivers spend driving on rough and uneven pavement during the repaving process.
The Mobility Authority is allowing these weekend lane closures to ensure the new Express Lanes open to
traffic in both directions by the end of the summer paving season. Full details about the closures can be
found at Drivers can also sign up at the website to receive text and email
alerts with detailed information about nightly lane and ramp closures.
