iirc all the bids for a concrete version (ala Florida) were twice as much for the steel design that was used, otoh California version also has to be earthquake resistant. I gotta give credit to all the engineering firms and Caltrans oversight. Very little downtime on 280, that would have been a traffic nightmare for entire peninsula.
- OrangeMango 7y ago$14 million for 375 feet in CA is ~$37k/ft A 620 ft concrete suspension bridge [1] in Chicago was $23 million, or ~$37k/ft A 1470 ft concrete and steel bridge [2] in Chicago was $33 million, or ~$22k/ft This ugly monstrosity in Florida was $9 million for 174 feet, or ~$51k/ft It's awfully pathetic.
