Document Description
Caltrans proposes to seismically retrofit the San Antonio Creek Bridge to withstand a future credible seismic event. The bridge is located in Santa Barbara County on SR 135 at PM R7.72, seven miles west of Los Alamos. The work would involve constructing anchor piles behind the north and south abutments, reinforcing the existing bridge columns, installation of four Cast-in-Steel Shell concrete piles and upgrading the bridge rail and treatments.
