Document Description
NOTE: Review Per Lead
The City of Los Angeles, in cooperation with Caltrans, is proposing to make improvements to the 6th Street Viaduct to improve this critical Los Angeles River crossing to an acceptable standard during a seismic event by either retrofitting the existing structure or replacing it entirely. The 3,500 ft long 6th Street Viaduct was built in 1932. Over the past 75 years, the concrete elements of the viaduct have been degraded by an ongoing chemical reaction, known as Alkali Silica Reaction, which has led to significant deterioration of the structure and loss of its seismic integrity, despite continuing efforts to arrest or limit its effect.
