An aerial view of the Walnut Creek freeway bypass. Downtown Walnut Creek is upper left, hemmed in by what is now Interstate 680, leading to Concord (right), Danville (lower right), and Walnut Creek on what is now Hiway 24 (upper left). 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 downtown streets to Interstate 680 and Hiway 24.
