The Golden Gate and Bay bridges have not only heavily contributed to the iconic San Francisco skyline, they serve as a collective engineering and aesthetic tour de force.
Architect Donald MacDonald, whose work continues on the redesigned Bay Bridge, gives an extensive overview of both bridges and thier places in San Francisco's history. Covering the politics and the financial history of each bridge, MacDonald moves on to discuss seismic measures, environmental impact, the "bridge aesthetic" (design) and how some cities are branding themselves through their iconic bridges.
