The State Route 126 Interchange Improvement project is being constructed in partnership with the County, Metro, and Caltrans, and once completed, is expected to provide significant traffic flow and safety improvements for area residents and commuters, reduced travel times and enhanced access to the Valencia Commerce Center development.

The project includes the construction of a grade-separated interchange at the existing signalized intersection of Commerce center Drive and State Route 126, new on-ramps and off-ramps on Commerce Center Drive and Henry Mayo Drive, the widening of State Route 126, the installation of new traffic signals, and the realignment of Henry Mayo Drive.

Construction was planned to progress in 6 distinct stages.
