Document Description
The California Department of Transportation (Caltrans) proposes to address localized scour on the western bank of Soquel Creek at the Soquel Creek Bridge (Br. No. 36-0013), on State Route 1 (SR-1) at post mile (PM) 13.31 in Santa Cruz County. The arch span bridge was originally built in 1947 and then widened in1971 and 1995. The proposed project will remove damaged sack concrete protection and install approximately 1,250 cubic yards of rock slope protection (RSP) along the western bank underneath the bridge. RSP is among various bank and shore protection materials and methods. RSP, also called rock riprap or riprap, consists of one or more layers of rock; it is placed along river and streambanks, or along ocean and lake shores to prevent erosion. Dewatering/diversion of the creek is anticipated in order to remove sack concrete and place the RSP. The projected is planned to start construction June 2023 and the estimated construction duration is 60 working days.
