Yuba County, California Bridges: Union Pacific Bridge across the Feather River

October 2013 (39.16364 Degrees, -121.61284) UP Trestle Bridge
Continuing upstream along the Feather River Bridge is an old Union Pacific Trestle Bridge with concrete piers supporting truss spans over the river. A really big caisson supports the river pier to protect it from debris coming downstream.
I wonder if the bridge was raised at some point and the rings around the piers is where the top used to be? The Union Pacific comes north out of Marysville on a big curve, crossing the river in a westerly direction and then goes north through Sutter County (see Google earth photo below).
On the east side of the river are precast box girder spans supported on steel H piles with reinforced concrete bent caps.
