Pine Hill Road Bridge Replacement

Pine Hill Road Bridge crosses over Swain Slough and is a 63-foot long three span timber bridge built in 1955. After being identified as structurally deficient by Caltrans and the Federal Highways Administration, the bridge was replaced with a 70-foot-long reinforced concrete bridge in accordance with the Caltrans Seismic Design Criteria Version 1.7. Since site-specific determination of ground motions was required for design of the new bridge, Langan performed a ground response analysis.
