|December 2004 (37.818 deg., -122.344 deg.) East Bay Bridges
This photo was taken a few years ago when they were building the skyway portion of the new East Bay Bridge. The old bridge is on the left and the new bridge is waiting for the drop in spans. The match cast segments were built in Stockton (see figure below) and brought to the site on barges. Each pair was lifted up with a jack and post-tensioned to form a balanced cantilever structure.
