[In fairness, the project's scope isn't confined only to folks who may have worked on the bridge or who were present at, say, the dedication ceremony. They're hunting for people who can contribute to knowledge of the bridge's legacy, from construction until the present.] The bridge opened to traffic Nov. 12, 1936, and the year-long 75th anniversary celebration still has events planned through November.
Here’s an excerpt from the Contra Costa Times about the Bridges and the San Francisco Bay Oral History Project, whose director is historian Sam Redman:
The goal of the interviews is to capture personal experiences of those who were there.
"We'd like to explore the people who worked on the bridge and are hoping to get their stories," Redman said, adding that while many of those involved in the bridge's earliest phase have passed from the scene, "there were many people -- including children -- who were at the opening ceremony."
