I have a copy of the U.S. Army Corps of Engineers master plan for the SF Bay Area, 1960-2020. It's a slip case of documents and maps.
Highlights:
- Five freeways up the Peninsula - US 101, I-280, Skyline (CA 25), Pacific (CA 1), and one out in the bay on stilts.
- Another Bay Bridge at Candlestick
- Possible second bridge to Marin - Alcatraz-Angel Island-Tiburon route.
- Fill in everything south of the Dumbarton Bridge to make new land.
- The north bay was to be for heavy industry. To support the Mare Island shipyards, Marin County to get steel mills.
- The peninsula was for "business machines". They got that right.
