Sacramento County, California Bridges: Southern Pacific Railroad across the Cosumnes River (2)

September 2013 (38.357684 Degrees, -121.343534 Degrees) Cosumnes River Railroad Bridge

Another view of the Southern Pacific Railroad Bridge across the Cosumnes River. It's amazing to me that this little bridge can handle the repeated blows of big diesel locomotives pounding across the steel girder superstructure. Perhaps that's why railroad engineers feel their bridges can easily handle an occasional earthquake.

Although this bridge has a diminutive superstructure it has a huge substructure. The big foundation and columns were more likely designed to resist the 100 year flood rather than the frequent live loads.
