I-680 Express Lanes From SR-84 to Alcosta Boulevard

The I-680 Express Lanes from SR-84 to Alcosta Boulevard Project will close the gap between existing and in-progress high-occupancy vehicle (HOV)/express lane projects directly to the north and south. The project extends for approximately 9 miles on northbound and southbound I-680 through Sunol, Pleasanton, Dublin and San Ramon.

Project benefits include:

  • Increased efficiency of the transportation system between SR-84 and Alcosta Boulevard to accommodate current and future traffic demand
  • Improved travel time and travel reliability for all users, including HOV and transit users
  • Optimized freeway system management and traffic operations

The project is currently in the preliminary engineering/environmental (PE-ENV) phase in which all needed studies are completed and compiled into the draft environmental document (DED). The DED, which was released in May, officially kicked off a 30-day public review period.

For additional information on this phase of the project and the virtual public meeting that took place on June 18th, please visit the Public Meetings tab.
