I-680 Southbound Express Lanes from Mission Boulevard Separation to Koopman Road Undercrossing

Reducing Travel Time for Commuters

This project involved converting the existing southbound HOV lane on I-680 into an Express Toll Lane, spanning from the Mission Boulevard Separation to the Koopman Road Undercrossing. It also included inside widening along I-680 and various ramp improvements at key locations to support smoother traffic flow and improved connectivity. Travel time for solo motorists using the toll lane has been substantially reduced with this project and commuters in other lanes also experienced a reduction in travel time.
