LA River: Sixth St / Whittier Blvd bridge 1839a

Sixth Street/Whitier Blvd bridge over the Los Angeles river. Built in 1932, it's a very long bridge (3500') spanning the LA river, various local streets, multiple railroad tracks, and two freeways that were built many years after the bridge (the I-5 and the 101). It has an unusual problem with the concrete that makes it vulnerable to collapsing in an earthquake.

The massive pillars at the east end of the bridge are surprisingly plain considering the effort made in building them.
