Posey/Webster Tube Seismic Retrofit
Project Description: The Posey and Webster Street Tubes are two immersed tunnels carrying vehicular traffic between Oakland and Alameda in the San Francisco Bay Area, California. Caltrans, the California Department of Transportation, under the seismic retrofit program, determined that the structures would be subject to liquefaction damage during a 7.25M level event along the Hayward Fault. Subsequently, a consortium led by Parsons Brinckerhoff of San Francisco, California was retained by Caltrans to carry out an extensive seismic study on the two immersed structures and to provide recommendations for the seismic retrofit of the two tubes. Tasks included performing a detailed seismic evaluation of the sites, developing and presenting alternative retrofit strategies.
