In the 1989 Loma Prieta earthquake, one section of the upper deck of the Bay Bridge’s eastern span collapsed onto the lower deck. The bridge was closed for repairs for a month. In 2002, reconstruction started on a self-anchored suspension bridge to replace the eastern span, and it is scheduled to open around Labor Day 2013.
