The Transportation Division of El Dorado County’s Community Development Agency
reopened Mosquito Road at the South Fork of the American River to one lane of traffic
at 12:00 p.m. on Friday, March 10, 2017.
Motorists and pedestrians should anticipate temporary concrete railing that narrows the
roadway to one traffic lane. A yield sign will require northbound downhill traffic to yield
to southbound uphill traffic. This one-lane closure, just south of the river, will remain in
place for several months until the permanent repair can be completed.
This part of the American River Canyon is experiencing numerous slides this year due
to the saturated soils. Please drive slowly, use caution and respect oncoming traffic.
We apologize for any inconvenience as a result of this construction and appreciate your
cooperation and patience until project completion.
