About the Project
This website is the result of two archaeological projects undertaken by the California Department of Transportation (Caltrans) and Anthropological Studies Center (ASC) at Sonoma State University in the South of Market area of San Francisco. The California Department of Transportation (Caltrans) funded the development of this Web site.
The projects were formally known as the SF-80 Bayshore Viaduct Seismic Retrofit (SF-80 Bayshore) Project and the San Francisco–Oakland Bay Bridge West Approach (SFOBB West Approach) Project. They formed a continuous corridor along the Interstate 80 freeway, from Main Street to the Route 101 Interchange in San Francisco. The SF-80 Bayshore and SFOBB West Approach projects were conducted as part of the environmental assessment and mitigation required by California regulations prior to the seismic retrofitting of the San Francisco-Oakland Bay Bridge. They were carried out to federal standards for archaeological projects.
Archaeologists monitored the SF-80 Bayshore project for the presence of archaeological features during seismic retrofit construction activities. Construction monitoring, feature identification and archaeological data recovery for the SF-80 project took place intermittently from 19 May 1999 to 11 December 2001. The process resulted in the identification of eleven archaeological features of which seven were evaluated as eligible to the National Register of Historic Places.
Archaeological excavations for the SFOBB West Approach project took
place intermittently from May 2001 to January 2003 across six city blocks.
Eighty-three historic archaeological features were identified, of which
over 40 appear to be eligible to the National Register of Historic Places.
Analysis for this project is currently in progress.
