Bay Bridge East span 2012: old span
The plan is to demolish the old span soon after the new one is complete. However, the bridge still carries 280,000 cars a day, and improvements have been made to keep it safer until then. Top right you can see a viscous damper that has been installed to help absorb stress during an earthquake. Bottom-right is the Bay Bridge Troll on the old span. It's still unclear as to whether the troll will be making his way to the new bridge.
