Welcome to Caltrans District 4

The History and Archaeology of Yerba Buena Island

This website was created as part of the Archaeological Mitigation for the San Francisco-Oakland Bay Bridge New East Span Project. The Federal Highway Administration and the California Department of Transportation jointly sponsored archaeological studies for this project in compliance with state and federal laws, including Section 106 of the National Historic Preservation Act. The NHPA seeks to achieve a balance between preservation of our nation's heritage and the development activities that are necessary to maintain and improve our standard of living and quality of life.
