State Route 9 Saratoga Creek Bridge

Caltrans began construction on the Saratoga Creek Bridge Rehabilitation on State Route 9 (SR-9), Saratoga, CA, in the spring of 2023. This project will maintain safe and stable connectivity along State Route 9 between the City of Saratoga in Santa Clara County and the community of Felton in Santa Cruz County. Caltrans recommends replacing the bridge, due to seismic and structural concerns. The rehabilitation project will allow the newly replaced bridge to meet seismic safety regulations.

Major work on Saratoga Creek bridge was completed in December 2023. Additional work including erosion control and landscaping is ongoing. All work is scheduled to be completed by the end of September 2024.

Lane Reductions

The project will be predominantly constructed during the day, but some intermittent night work is expected. During construction of the new bridge,  there will be mainly fulltime one-way traffic control. At specific announced periods, there will need to be a full closure and detours will be established.
