The Metro Silver Line began service on December 13, 2009, connecting the South Bay and San Gabriel Valley to Downtown Los Angeles. The Silver Line runs between the Harbor Gateway Transit Center and the El Monte Station via the Harbor Transitway on the Harbor Freeway and the El Monte Busway on the San Bernardino Freeway.

The Silver Line will undergo several service enhancements along with amenity and station improvements, some of which are part of the agency’s Congestion Reduction Demonstration Project that converted existing carpool lanes on both the San Bernardino Freeway and the Harbor Freeway into ExpressLanes .
Project tasks related to Metro Silver Line include the following:
