Composition of a bridge

Most of the time I live in Oakland, CA. There is a huge bridge that links the East Bay (Oakland) with the West Bay or, as San Franciscan's like to call it, San Francisco. A big part of this is being replaced with a brand new bridge in 2013. This 2 mile long bridge has two decks with five lanes on each. Tonight they will close it for four days, take part of it down and reconnect a new temporary part for us all to drive on while they connect the newly constructed bridge to the existing half way point called Treasure Island. The bridge was featured in a Discovery Channel show called Extreme Engineering. The whole thing is amazing to me, in the same way that a train or a plane arriving on time is. I have trouble just finding the other shoe every morning. Anyway you can see the whole story at this great web site
