ELYSIAN VALLEY — The Eastsider spotted this 1937 news reel posted on Facebook page of the Citizens Committee To Save Elysian Park. It shows the aftermath of a 1937 landslide that damaged the Riverside Drive bridge along the L.A. River. “Starting with a gap only an inch wide, Mother Earth moves a mountain into the lap of the city,” the news announcer proclaims.
Nearly 70 years later, that landslide was mentioned in a 2006 report about replacing the bridge, located near interchange of the 5 and 110 Freeways, with a new span, which is now under construction. Says the report:
According to the Seismic Hazard map, a large landslide area is located just above Riverside Drive approximately 328 to 656 ft from the bridge; the approach may overlie material involved in the slide …The slide was active in 1937 when it blocked Riverside Drive. Because the Los Angeles River is now confined to a concrete channel, undercutting should no longer be a problem, but any substantial excavations within or below the hillside must evaluate the potential for destabilizing the slope.
