LBJ Express FAQs - LBJ Freeway Capacity

According to the Regional Transportation Council 2030 Mobility Plan, the eventual demand for this portion of LBJ is 500,000 vehicles per day by 2020. There is no way the facility can be built to handle this demand. Even upon completion, the roadway would be outdated.
