Cee’s challenge is about bridges: https://ceenphotography.com/2016/07/05/cees-fun-foto-challenge-bridges-2/
I took the following photos along the famed Cabrillo Highway (or Highway 1) south of Carmel-by-the-Sea. Except for the footbridge below, the other bridges were built during the Depression from 1931 to 1932. Despite the challenging terrain and occasional bad weather, the bridges were built on schedule, and Bixby bridge was completed under budget! Today those terms, on schedule and under budget, are unheard of in major construction projects.
