Oakland Substation, Foot of east span of bridge, Oakland, Alameda County, CA

Significance: The building was constructed as an electrical substation for the interurban trains that originally ran across the Bay Bridge from Oakland to the Transbay Transit Terminal in San Francisco. It is similar to the electrical substations on Yerba Buena Island and in San Francisco that were constructed at the same time and which were previously determined eligible for National Register listing as contributing components of the historic bridge. Although electric trains no longer run on the bridge and this building is now mainly used for storage, it retains its association with the bridge and possesses a high degree of integrity. This building therefore appears to be eligible for National Register listing as a contributing component of the San Francisco-Oakland Bay Bridge. Both this building and the adjacent Key Pier Substation are within the state highway right-of-way.
