BulletImportant Notice:   Mosquito Road re-opened on Monday, July 24th @ approximately 2:15 PM. The public attended a ribbon cutting ceremony that began @ 1:30 PM on the Placerville-side steel gate just up the road from the bridge. Representatives of Mitchell Engineering (the prime contractor), County staff, Engineering and Geotechnical consultants, County executives, and members of the general public were in attendance. 

BulletThursday, July 20th – Began the installation of metal beam guardrail (MBGR) on the upper road. This work includes driving guardrail posts into the shoulder area, blocking and bolting metal rail to the posts and installing terminal sections (breakaway end sections)

BulletFriday, July 21st – Cutoff the top of piles for the small Timber Pile Retaining Wall (lower road); Continued and completed the installation of the MBGR on the lower road. Installed asphalt concrete (AC) dike and AC overside drains.  

BulletSaturday, July 22nd – Erosion control subcontractor placed bonded fiber matrix slope stabilization throughout the project site. This material is seed, mulch fiber, and tackifer (natural glue like substance) and will provide a protected slope surface until vegetation is reestablished.

BulletSunday, July 23rd – The concrete fascia for the Soldier Pile Retaining Wall was dry sacked to give the surface a finished appearance. Dry sacking is performed manually by rubbing the concrete surface with a burlap sack, water and dry cement. This fills in the pores and smoothes the surface.

BulletMonday, July 24th – In the morning, the contractor continued and completed dry sacking the concrete fascia for the Soldier Pile Retaining Wall. They wet swept the entire roadway and tested the surface drainage conveyance system with the use of water. The County Maintenance Department installed various reflective guide markers.

In the afternoon with the work being deemed substantially complete, the ribbon cutting ceremony occurred @ 1:30 PM and the road was opened at both the northerly and southerly gates for public use, 204 days after they were closed due to “… a massive mudslide that destroyed part of the hillside and forced the closure of Mosquito Road, one of two roads that lead to the Mosquito area and Swansboro community..”. Hurrah!! Mosquito Road is open. The road repair is substantially complete.

General Note:  This completes the series of status updates. Minor construction work may still be required and will be performed using appropriate traffic control methods. Thanks to the Mosquito and Swansboro community for their patience.

Please drive the road safely during the completion of the Project’s work and once the Project is completed. Share the road, both with the construction/maintenance workers and with your fellow residents. Please drive defensively and safely.


Thanks to the Mosquito Fire Protection District and Firehouse Country Kitchen for posting these status updates during the repair and for providing the most up-to-date information for the benefit of the area residents.
