PRESS RELEASE MAP

The United States Army Corps of Engineers’ (USACE) contractor, Granite Construction, has begun work to widen the Sacramento Bypass flood control structure. The Sacramento Weir Widening Project is taking place along Old River Road, also known as County Road 22, just north of the City of West Sacramento city limits. This crucial step toward bolstering flood control measures along the Sacramento River aims to enhance flood stage management both upstream and downstream of the Sacramento Weir during high-flow events, thereby mitigating flood risks and safeguarding the areas adjoining the Sacramento River.

As this project gets underway, it is imperative for commuters to anticipate potential delays stemming from project construction, which is anticipated to persist until late 2026. Motorists are encouraged to exercise caution, adhere to construction signage, and reduce speeds while navigating through the construction zone. When possible, motorists are encouraged to take alternative routes.

Motorists will encounter a temporary all-way stop intersection situated at the northern end of the existing Sacramento Bypass bridge structure, where County Road 126 converges with Old River Road. This temporary measure, including the installation of stop signs and detour roadway, is anticipated to be implemented by August 21 and will remain until the weir extension component of the project is completed in 2025.

A key element of the project entails the construction of a 1,500-foot-long extension of the Sacramento Weir, stretching northwest along Old River Road. This extension will be accompanied by essential improvements such as levee enhancements, roadway upgrades, utility enhancements, and fish passage improvements.

To accommodate the construction of the weir extension, a section of approximately 1,000 feet of Old River Road will be temporarily removed. In its place, a detour route will be established. This detour is projected to be operational for an estimated two-year period during the course of the weir extension construction.
