At the October 2009 AC Transit Transbay Taskforce meeting, attendees were treated to a great historical presentation. Heather Price from William Self Associates presented facts and findings from the excavation process related to the construction of San Francisco's Temporary Transbay Terminal. She was followed with a presentation by Joyce Oishi on the salvage and historical preservation efforts within the existing Transbay Terminal.

Several smaller items salvaged from the Terminal will be on display in an interpretive exhibit at the new Transbay Transit Center (not the Temporary Terminal), while larger items not taken by local museums will be properly recycled.
