Title

State Route 163 - Friars Road Interchange Project

Description

DFG is intending to execute a Lake and Streambed Alteration Agreement pursuant to Section 1602 of the Fish and Game Code (SAA # 1600-2009-0381-R5) to the project applicant, City of San Diego. The applicant intends to alter the stream to construct a bridge crossing the San Diego River and install fill in an unnamed tributary to the San Diego River to accommodate construction of a flyover bridge connecting Ulrich Street to southbound SR 163. The new bridge crossing the San Diego River will be an independent structure just west of the existing bridges. It will be designed to pass 100-year flood events, and will be supported on pier walls (above-ground structures) and pile foundations (below-ground structures). Piled will be pounded into the ground to the appropriate depth, and will have footings approximately three feet deep and sex feet wide constructed at the top of the below-ground piles. An excavation approximately 10 feet wide will be made for the pier footing, except that the footing for the two piers located on either side of the river's low-flow channel will be 10 feet wide with an excavation width of 12 feet. Pier walls for the spans over the river will be approximately two feet thick, and would range from 160 to 260 feet long (including the existing pier walls), parallel to the direction of river flow. The footing and piers will be constructed in line with the existing footing and piers on the existing bridge.
