|April 2014 (37.78749 Degrees, -121.30794 Degrees) Mossdale Railroad Bridge
There is a lot of good information about this bridge. The Trainorders website discusses the history of the bridge, disasters that occurred on the railroad line (between Mococo and Lathrop), and the different trains that it carried.
Apparently, the first bridge at this site (built in 1869) was the final link of the Transcontinental Railroad. Before it was completed passengers had to get off in Lathrop and take a ferry across the river before boarding another train on the opposite side.
