The Tribune clipping, dated June 19, 1958, attached to the back of the photo reads "NEW TRAFFIC PATTERN Walnut Creek will have projects in $2,000,000 master plan finished by end of next week and dedication will be held on July 13. [Projects identified in capital letters on the photo as follows] They are (A) Culverting of Walnut Creek stream channel and building of new street over it; (B) extension of Mt. Diablo Blvd.; (C) extension of Cypress St.; (D) Lincoln Ave. widened with new creek bridge; (E) extension of West Broadway,; (F) new California Blvd from Newell Ave. to Mt.

A park, industrial buildings, and houses are scattered throughout the photo.
