Road Work to Construct Four-Lane Road

Published on June 25, 2025

Road Work to Start Next Month to Construct Four-Lane Road Between Missouri Flat Road and State Route 49 in Placerville

(PLACERVILLE, CA)

El Dorado County’s Department of Transportation will be performing road work beginning in July 2025 and continuing through December 2026 at the following locations as part of the Diamond Springs Parkway Phase 1B Project:

• On Missouri Flat Road between Golden Center Drive and China Garden Road
• On State Route 49 between Truck Street and Pleasant Valley Road
• On Pleasant Valley Road between Fowler Lane and Toyan Drive
• Along Bradley Drive, Throwita Way, and Old Depot Road

The work will require occasional shoulder and lane closures during which motorists should expect delays. These closures are necessary to ensure motorist and worker safety while the County’s contractor constructs a new 4-lane roadway between Missouri Flat Road and State Route 49. 

Motorists are advised to slow down through the work zones and allow extra time in order to arrive at their destinations on time.

El Dorado Trail users should also be aware that parking will no longer be available along Old Depot Road or near the front of the Sierra Door building.  Instead, please use the southern portion of the parking lot at 4300 Missouri Flat Road or 4369 Golden Center Drive for trail parking.

For questions regarding this project, please contact the County’s Transportation main line at (530) 621-5900 (select Option 3 for Engineering).
