Permit No.19940 - Bridge Authorization at Mile Post 194.52

The contract authorizes the continued use of a 927-foot-long, three-segment bridge located at Mile Post 194.52 in California, originally constructed in 1914 and 1948, prior to the 1977 flood control plan. The structure consists of three distinct sections: Segment A is a 50-foot Deck Plate Girder - Open Deck built in 1948 serving as the northern approach, Segment B is a 481-foot three-span Deck Truss Riveted - Open Deck also built in 1948 that spans the main channel without any in-channel piers, and Segment C is a 396-foot, 13-span Deck Plate Girder - Open Deck constructed in 1914 forming the southern approach. Authorization is needed to legally recognize and maintain this pre-existing structure despite its non-compliance with modern flood control standards. The permit is issued by the Central Valley Flood Protection Board under Permit No. 19940 and is posted on May 26, 2026, as a forecasted action. Primary contact for inquiries is Jennifer Calles, Senior Environmental Scientist, reachable at 916-837-3683 or jennifer.calles@cvflood.ca.gov, with additional support from Stephen Cheney, Director of Structure Design & Environmental, at 402-544-3227 or slcheney@up.com. The bridge is located entirely within California, and the authorization aims to ensure the structure’s lawful operation while acknowledging its historical construction and unique design features that predate current regulatory frameworks.
