Scope of Work:
This section of the I-80/I-680/SR 12 Interchange project would replace the existing single-lane EB SR 12 to EB I-80 connector with a new two-lane connector bridge structure that will be constructed and designed to accommodate future project phases. The project will also construct a new slip ramp from EB SR 12 directly to Green Valley Road (GVR) and a new braided off-ramp from EB-I-80 to GVR and southbound I-680.
Driver Benefits:
The project will benefit motorists and the local community by improving travel times, reducing cut-through traffic on local streets, and enhance safety by streamlining connections for motorists transitioning between these three major state routes linking the Bay Area, the Napa Valley, and Sacramento.
