Sacramento Weir Widening Project
Aerial image shows ongoing construction of the Sacramento Weir Widening Project along the west bank of the Sacramento River in Yolo County, California, Nov. 16, 2023. Current progress includes completed work on the north setback levee, installed site access ramps and office trailers, cement soil mixing and piles for the vehicle bridge pile caps, and the commencement of foundation work for the fish passage structure. The project is an approximately $350 million 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 flow over the river channels and into the bypasses during severe flood events, ultimately reducing flood risk for the 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.
