BRIDGEPORT, Calif. (AP) - A forest fire in California's eastern Sierra Nevada continued to grow Wednesday, and the effect on travel was increasing, officials said.
State Route 108 was closed from the Alpine-Mono county line to U.S. 395, which was already shut down in the mountainous region about 200 miles (320 kilometers) east of Sacramento, the California Department of Transportation said.
Additional firefighting resources were summoned as the blaze grew to more than 4Â½ square miles (11.6 square kilometers).
The closure of U.S. 395 extends from the town of Bridgeport to just south of the community of Walker, Caltrans said.
The so-called Boot Fire began Tuesday in the Humboldt-Toiyabe National Forest. Evacuation orders remained in place for the Bootleg, Chris Flat and Sonora Bridge campgrounds. Unspecified structures are threatened in the Burchum Flats area east of Walker Canyon.
To the west, another fire in El Dorado County has prompted evacuations and road closures.
