An aerial image looking southeast at ongoing foundation and deck construction for the new vehicle bridge and expanded weir structure, part of the Sacramento Weir Widening Project along the west bank of the Sacramento River in Yolo County, California, Sept. 25, 2025. The project is a collaborative effort between the U.S. Army Corps of Engineers, California’s Central Valley Flood Protection Board, California Department of Water Resources, and the Sacramento Area Flood Control Agency to widen the existing 1,950 foot weir an additional 1,500 feet. The expanded weir and bypass will allow excessive floodwaters to move over the river channel and into the bypass system during severe flood events, reducing flood risk for more than 500,000 people in the greater Sacramento region. The work is part of the larger American River Common Features 2016 project that will modernize Sacramento’s aging flood infrastructure.
