Joseph P. Strauss - World famous for very good reasons, designed by Chicago chief engineer Joseph P. Strauss and consulting architect Irving F. Morrow, it opened 1937. this ever-present Art Deco wonder is an unforgettable experience, no matter how many times you visit. It took 52 months to design and construct. I recommend a biking over bridge from San Francisco to Sausalito. You can then take a ferry back to the City.
