Mosquito Road Bridge Project-Construction
For the overall project history, including the planning and design phases of development, visit the main Mosquito Road Bridge Project page.
The construction contract for the project has been awarded to Shimmick Construction Company, Inc. by the Board of Supervisors on Tuesday, May 17, 2022.
County DOT Maintenance is doing their best to keep up with Mosquito Road and Rock Creek Road repairs. They have been performing patch repairs of the worst areas (Mosquito Road, Mosquito Cutoff, and Rock Creek Road) and will continue to provide maintenance repairs as needed and scheduled.
The Bridge Project paving of Mosquito Road extends approximately 500 feet south of the beginning of the bridge and approximately 300 feet north of the end of the bridge. This new paving will be installed following the complete construction of the new bridge. County DOT Maintenance will continue to pursue additional funding for possible future road resurfacing and improvements.
If you have an issue with a particular pothole or maintenance, you can submit your request for repair. DOT Maintenance will add your request to their list.

Updated on 6/23/22: Mosquito Road is anticipated to be closed to through traffic beginning approximately July 5, 2022 and ending approximately August 8, 2022(PDF, 177KB). Closure limits are anticipated to coincide with the current gate locations and will be coordinated with schools and emergency response as needed. Intermittent lane closures and flagging should also be anticipated as needed for mobilization of construction equipment and materials. During this time, it is also anticipated that tree removal operations will occur for the bridge project, and routine maintenance of existing Mosquito Road Bridge will also be conducted. For additional details refer to the PCMS boards located along the roadway and to this project website. Read the road closure notice.
The Mosquito Road Bridge Replacement Project is anticipated to result in Mosquito Road closures(PDF, 227KB) at approximately the existing gate locations for up to 10 weeks and will be coordinated with school schedules. This Project may also have intermittent flagging operations and lane closures along Mosquito Road, Rock Creek Road, and the neighboring roadways to the Project to facilitate Project operations and mobilization of large equipment and materials. For additional details refer to the Project’s construction website.

Traffic & Staging Overview
Mosquito Road Bridge Replacement Project is anticipated to be built in three stages(PDF, 281KB):
- Stage 0 involves the realignment of Mosquito Road on the north side of the canyon to allow for the new bridge abutment to be constructed on the north. This work is anticipated to be performed under a full road closure.
- Stage 1 involves construction of the new bridge and approach roadway (on both north and south sides of the canyon). This work is performed off alignment of current Mosquito Road and may require intermittent flagging and lane closures.
- Stage 2 involves construction of the final roadway tie-ins, bridge barrier rails (and metal beam guardrails), and final restoration operations. This is the final stage of construction and is anticipated to be performed under a full road closure and intermittent flagging and lane closures as needed.
