The LBJ Express project involves adding managed toll lanes along I-635 and I-35E in Dallas, Texas. Construction is underway and on schedule, with the first segment set to open in late 2013. When complete, the project will add 4-6 new managed lanes and reconstruct 8 existing general purpose lanes. Over 60% of construction is now complete, including excavation of subsurface lanes. The managed lanes will be called TEXpress Lanes once the project is finished in late 2015.
