|December 2012 (38.9573 Degrees, -120.4861 Degrees) Eleven Pines Road Bridge|
It's a three span steel girder bridge on tall reinforced concrete piers.The piers have an interesting flare that ends in a concrete key to attach to the steel end diaphragms. This bridge is in the middle of nowhere and so they must have built a concrete plant nearby.
The photo below shows what the river looks like under this bridge (in December).
