State Highway 99 Cosumnes River Bridge Replacement Project

Project Facts

Purpose
The purpose of this project is to provide a safe and maintainable roadway; which preserves the integrity of the SR 99 corridor while meeting transportation needs.

Need
The California Department of Transportation (Caltrans) proposes to replace the Cosumnes River bridges and the Cosumnes River Overflow bridges with two new bridge structures. The current structures are in need of replacement due to age, wear and outdated design to improve overall mobility and safety through this corridor. The southbound McConnell underpass and the existing northbound McConnell OH structure will be replaced with a single McConnell OH structure for both northbound and southbound SR 99. The scope of work also includes improving the Dillard Road overcrossing.
