More pics. I will be posting more of the best, but all the rest I have up at http://picasaweb.google.com/benablackburn
Main tower construction. The red iron will support Enerpac Strand Jacks to lift sections of tower up. They warn everybody on the traffic reports not to stare as they drive over the old bridge as they are lifting them. I just take pictures!
They had just set one of the last sections of falsework for the pre-fab suspension section.
This is the west end of the suspension span. The round yellow things serve the same function as the dowels on your dining room table! The "Geordi La Forge Visor" on the corner is where the suspension cables wrap around and under. They anchor at the opposite end.
I didn't see what they were moving with this frame, but it was interesting the way they were counterweighting to be able to swing the load under the end of the deck
This is looking west towards Treasure Island. The tunnel is right behind the cranes. An interesting tidbit I picked up is that all those support columns are the same length. Where the ground is higher they dig the hole deeper and then there is a casing around the column. This means that in an earthquake everything can move together instead of the shorter columns getting ripped apart as the tall ones sway. The skinny columns in the background are holding up the "S-Curve" temporary section C.C. Meyers slid in on a Labor Day Weekend a couple of years ago to give them room to connect the new bridge straight to the tunnel. I guess they aren't too worried about it coming down in a quake! The current Google Sat pic is just after they swapped bridge decks like some giant monorail switch. http://maps.google.com/...
