The Los Angeles River had been known to flood many times in Los Angeles early history, but never, as it had done during a four day storm starting on March 2,1938. Most of the rain fell on the fourth day and this was the 5 th largest flood in history. The Southern Pacific's first crossing is seen here washed out with two spans missing.

One of the great engineering marvles at the time was to concrete the L.A. Riverbed by the Army Corps of Engineers. Dragline cranes, power shovels and dump trucks worked by the hundreds to lower the floor of the L.A. River. This photo is looking upstream from under the Pasadena Freeway Overpass.
