Here is a new item on the New Bay Bridge: <http://cirrus.mail-list.com /seaint-seaosc/85769188.html bridge.html> The new bridge is about 10,000 feet long, 2000 feet is the steel part including the SAS span , where about 2600 A354 BD anchor rods and bolts are used. The remainder, the 8,000 feet long portion is R/C post-tensioned segmental spans. The latest news item says that some post tensioning tendons have corrosion.
