An aerial view of the Walnut Creek freeway bypass. Downtown Walnut Creek is left center, hemmed in by what is now Interstate 680, leading to Concord (right lower), Danville (top), and Oakland, on what is now Hiway 24 (right upper). Several of the roadways are virtually complete. Bridges and overpasses are works in progress. Houses and orchards are on all sides of the interchange. The Walnut Creek bypass is designed to divert commute traffic off downtwon streets to Interstate 680 and Hiway 24.
