The one across the freeway is big. Real big. Then there's another bridge across the tributary road that's not as big. Still pretty big.
They build bridges over spans like this all the time. The only thing odd about this bridge is its width, not span length. Even then, the increased width is going to result in a lower cost per area than a skinny bridge.
Why would it be cheaper per area when it's got so much more load?
I was talking about width versus cost per area of bridge. There are fixed costs to building a bridge and bridges with longer spans usually cost more than bridges with shorter spans above a certain minimum span length. However, for width, you only need to pay the additional cost of making the bridge wider while the costs of building a bridge at all get spread across more area.
I see.
Well, I'm sure if you dug down into California's budget you could find it.
