Package 5 is the fifth of seven packages improving the distribution of three major freeway movements at this interchange by reconfiguring the ramps and access to local streets. This component of the regionally significant Interchange project would construct a new SR 12 (West)/Red Top Road/Business Center Drive partial interchange, extend Business Center Drive from its current terminus westerly across SR 12, connecting with a realigned Red Top Road at the existing I-80/Red Top Road interchange. Together, these improvements will benefit motorists and the local community by improving travel times, reducing cut-through traffic on local streets, and enhance safety and operational efficiency for motorists along the I-80/I-680/SR-12 Interchange linking the Bay Area, the Napa Valley, and Sacramento.
