No freeways! But it was different. The bay bridge had only opened a few years prior and the bay area pop was low enough not to need them yet. By the time “Bullitt” rolled around, the peninsula had begun to fill out.
I am curious about the sand dunes on piece M6. It appears they were cleared and roads were put in, but perhaps the Great Depression led homes in that district to become abandoned, and the dunes took over once more?
That doesn't seem to jive with the aerial photos used to make the WPA model. Some roads are clearly covered by the dunes, which means the roads were built through the dunes without clearing the dunes entirely?
