News release: Seismic work underway on Castaic Dam’s tower access bridge
The California Department of Water Resources begins construction on Castaic Dam’s tower access bridge in Los Angeles County to reduce seismic risks during a major earthquake. … Work on the over 500-foot-long bridge consists of strengthening the three bridge piers and installing various components to the bridge superstructure to allow for controlled movement during a seismic event. Each pier will be encased with a reinforced fiber wrap compound, which requires the temporary drawdown of Castaic Lake that began in early May.
