Watch the free documentary screening of “Bridging Urban America” at San Francisco Main Library on Wednesday, July 26th from 6:00 pm to 8:00 pm in San Francisco, California.

This documentary celebrates Ralph Modjeski, the chief engineer for the San Francisco-Oakland Bay Bridge, who designed bridges that had significant impact on urban development and commerce.

This film is a tribute to innovative engineering and to bridge workers during two eras of transit, taking a deeper look at the scientific mind and artistic soul of a Polish-born, Paris-trained immigrant who contributed to the building of a modern America.
