(PLACERVILLE) – On February 9th, 2021, El Dorado County Department of Transportation will submit to the Board of Supervisors a High Cost Project Agreement that will secure full construction phase funding for the Mosquito Road Bridge at South Fork American River - Bridge Replacement Project (Project).

This Agreement secures the Highway Bridge Program construction financing plan with the California Department of Transportation and the Federal Highway Administration.  In 2011, the Project was awarded Federal Highway Bridge Program funding to start the project environmental and engineering work.  After years of study, design, community meetings, public outreach, environmental clearance, and utility coordination, the Project is finally fully funded and scheduled to break ground with construction next year.  The existing one-lane suspension bridge still requires annual closures for maintenance work and has the most expensive maintenance costs of all the County's vehicle bridges.

Once the Agreement is approved, Transportation will be finalizing the construction bid package and advertising the Project for bids. Construction activity is anticipated to begin in mid-2022. After the new bridge is complete, the existing 1939 suspension bridge and roadway is planned to remain in place for cyclists, pedestrians, and river access.
