Since they were concrete, I thought the constant vibrations from small earthquakes would weaken them and over time render them vulnerable to earthquakes. They've thrown a lot of money at that bridge, and have another $250 million to go, but it seems as if they will be able to keep it functioning. Thanks for the find. That was fascinating.
