MoPac Intersections

Crews are almost ready to open the La Crosse Avenue bridge and one northbound and one southbound MoPac mainlane below the bridge.  Anticipate the mainlaines to open sometime on April 16th and the bridge to open early Friday morning, April 17th, weather permitting.  Signals will be in place and the sidewalk will open in the coming weeks.

Prior to the bridge opening, the temporary traffic signal as southbound MoPac and La Crosse Avenue will be removed.  La Crosse Avenue will have a dedicated right-turn lane onto southbound MoPac and southbound MoPac will have a dedicated right-turn lane onto La Crosse Avenue, similar to the intersection at northbound MoPac and La Crosse Avenue.

Upcoming Work

Westbound La Crosse Avenue to Northbound MoPac Detour

Construction continues on MoPac mainlanes.  When the La Crosse Avenue bridge and extended MoPac mainlanes open to traffic, crews will close the dedicated right-turn lane into northbound MoPac from La Crosse Avenue for reconstruction.  During this time, drivers will be directed to southbound MoPac to use the turnaround at South Bay Lane.  Additional details will be shared as work progresses.

Invasive Species Control

TxDot is working with the Lady Bird Johnson Wildflower Center to develop a plan to stop the spread of an invasive plant species called Rapistrum rugosum, commonly known as bastard cabbage, within the MoPac Intersections project limits.

According to the Wildflower Center, “This invasive plant outcompetes our native wildflowers by blocking sun with its broad leaves.”  The invasive plant can wipe out entire fields of wildflowers and thrives along new roadside and lands cleared for development

Crews will mow the area (including wildflowers) between Slaughter Lane and Slaughter Creek on the east and west side of MoPac once weather conditions allow.  When construction is complete, the area will be seeded with a new wildflower mix developed in partnership with the Wildflower Center.  You can learn more about this and other invasive plant species by visiting the LBJ Wildflower Center Website at
