Mosquito Ridge Road near Foresthill will reopen to all traffic at 8 a.m. today.

A portion of the road has been closed for public and firefighter safety because of the American fire burning in Placer County northeast of Foresthill.

But, as firefighters reach containment of the fire, emergency vehicle traffic on the road has decreased, said Gwen Ernst-Ulrich, the forest’s acting public affairs officer, in a news release.

The fire, which started Aug. 10 and has burned 26,817 acres, was 99 percent contained as of Thursday night, officials reported. The cause is under investigation.

Three Forest Service roads, two popular trails and a campground within the fire area remain closed until further notice.

The roads include Deadwood Ridge Road from Foresthill Divide Road to the road’s end, Foresthill Divide Road from the intersection of Humbug Canyon Road to Robinson Flat and Flat Ravine Road from Robinson Flat Campground to Mosquito Ridge Road.
