Construction of a new I-680 Northbound Sunol Express Lane will begin in early 2018. This first phase of the project will widen the existing freeway and construct a new ~9-mile express lane and associated improvements on northbound I-680 between Auto Mall Parkway and SR-84 in Alameda County, providing congestion relief in the corridor. The project also includes upgrades to the adjacent southbound I-680 Sunol Express Lane, modifying the access configuration from controlled access to a near continuous access configuration, similar to that on the I-580 Express Lane corridor through the Tri-Valley.
Alameda CTC plans, funds and delivers transportation projects and programs throughout Alameda County, Calif., and distributes funds from Measures B and BB and the Vehicle Registration Fee.
