This is so cute! Seems that even in California, people are ditching the single-car commute, and using car pools or transit. This impacts all the horrible bridges, who rely on carbon-spewing in the form of tolls. Now they are jacking up the tolls to pay for seismic upgrades, which will cause people to drive less. I don't think they will win.
Retrofitting a bridge is expensive work. As you can see in the picture, if you determine that the columns are weak, what are you going to do? What if the deck has a chance to slip off the expansion joints, like Oakland? I always thought the best thing they could do was to put in a red light system to prevent the decks from being jammed with cars. They could go further by putting in signals once an earthquake is detected.
