(PLACERVILLE, CA) -- El Dorado County’s Department of Transportation (DOT) will be performing road
work on Mosquito Road from 0.6 miles north to 0.8 miles south of the Mosquito Road Bridge for tree removal,
bridge maintenance, and north roadway tie-in work. The work requiring road closure within these limits is
anticipated to begin July 5, 2022, and continue through August 8, 2022. The construction work will require full
closure of Mosquito Road. 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 ensure motorist and worker safety while the County’s contractor removes trees on
the north limits of the Project and performs roadway realignment for the north roadway tie-in. The County DOT
Bridge Crew will also be performing bridge maintenance work on the Mosquito Bridge while the roadway is
closed. The full closure work from July 5, 2022, through August 8, 2022, is scheduled while school is out of
session. Extension of this time frame may be needed once the Project schedule is updated. Further notification
will be provided at least two weeks in advance if extension of the August 8, 2022, closure is required.
On the week of June 27, 2022, tree removal will also commence on the south Project limits, which will not
require road closure. Mobilization of tree removal equipment will occur with pilot vehicles. The traveling
public is advised to reduce speeds, watch for pilot vehicles, and allow extra time for travel. Every effort will be
made by the County’s Contractor to minimize public impact during the tree removal work on the week of June
The County sincerely appreciates the cooperation and patience of motorists who use this roadway, and we
apologize for any inconvenience resulting from these closures.
For questions regarding this construction, please contact the County’s Transportation main line at (530) 621-
5900 (select Option 3 for Engineering).
