Bill Baker was born at Alta Bates Hospital in Berkeley in 1935. This interview marks the third time that Baker was interviewed by the Regional Oral History Office: the first two interviews cover his long career working with the UC Office of the President and thus that work is not covered in this interview. In this interview, Baker discusses the few years that he spent working for the Division of Bay Toll Crossings – a predecessor of the California Department of Transportation (Caltrans). During that time, he served as a structural engineer, working on the ground (and on the Bay Bridge) helping with the removal of rail tracks from the lower deck of the bridge and related work. He also discusses his work since retirement in dispute resolution, including work related to retrofitting the Bay Bridge and building the new eastern span of that bridge.
