Chris Carlsson will present a historic look at the San Francisco-Oakland Bay Bridge, how it has changed over time, going from two-way traffic on the top deck (3 lanes in each direction) with trains and trucks on the lower deck, to today's new span. The halfway-across-the-bay bike lane will get a close look too.

Explore Shaping San Francisco:
Discussions and reflections on the history of Bay Area ecological activism, based on oral histories documenting the past 50 years.
Ecology Emerges is an oral history gathering project to explore the past 50 years of ecological activism in the Bay Area and the role that individual and institutional memories play in the development, policy proposals, and interrelationships that together make up the existing networks of ecological politics. We document the living ecological activist movement, in their own words, but also in a larger context of urban growth and globalization.
