El Dorado County to Perform Crane Work on Mosquito Road Bridge Replacement Project,

Road Closure Required

(PLACERVILLE, CA) -- El Dorado County’s Department of Transportation (DOT) will perform a monthly inspections and maintenance of the crane boom extension and crane located at Pier 3 of the bridge replacement project north of the river on Mosquito Road. These safety efforts will require road closures each month.

The next closure for the inspection and maintenance work will be on Saturday, December 6, 2025. The crane maintenance will require full closure of Mosquito Road at the gates, from 0.6 miles north to 0.8 miles south of the old Mosquito Road Bridge. The closure will begin Saturday, December 6, 2025, at 7:00 am and open by 12:00 pm that same day. A detour has been established via Rock Creek Road for which motorists should expect delays and allow extra time for travel.

The closure is necessary to lay the crane boom down on Mosquito Road at the north project (Pier 3) location to perform crane inspection and maintenance. Mosquito Road will be impassable until the work is complete, and the boom is raised back into position. Mosquito Road will be closed at the gates to ensure motorist and worker safety while the County’s Contractor performs the crane work. The Mosquito Road closures will occur monthly for the duration of the project. Notices will be posted two weeks in advance of each closure.          

In case of an emergency, coordinate with Emergency Services for passage through the work site.  

The County sincerely appreciates the cooperation and patience of motorists who use this roadway, and we apologize for any inconvenience these closures cause.

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