The freeways that we drive on are much-ignored marvels of engineering. They are (mostly) angled to shed water properly, amazingly smooth, have occasional beautiful (yes, beautiful!) overpasses and truly amazing tangles where major routes cross each other. Plus, they have safety structures, signs, striping and lighting. We are so lucky, and (mostly) we don’t even know it, and never think about it. As a kid spending some time in Mexico, I marveled at these roads each time we returned home. These giant structures support the south side of the Carquinez Bridge, in Crockett. Some of these pillars sit next to modest houses, making an interesting juxtaposition.
