Angeles Forest Highway

The Angeles Forest Highway is a 25-mile (40 km) road over the San Gabriel Mountains in Los Angeles County, California. It connects the Los Angeles Basin with the Antelope Valley and western Mojave Desert. Maintained by the Los Angeles County Department of Public Works, the highway is designated as County Route N3 (CR N3) or Forest Highway 59 (FH 59); the route numbers are unsigned, but noted on many maps. This is also the route for the proposed State Route 249, but the California Department of Transportation (Caltrans) has no plans to take it over and officially adopt it as part of the state highway system.

Running between State Route 2 and State Route 14, the Angeles Forest Highway passes through the Angeles National Forest, and a western section of the San Gabriel Mountains National Monument. It is used primarily for recreation, although a significant portion of its traffic comes from commuters living in the Antelope Valley. It a well-known alternate to State Route 14 in this regard, and is known for its numerous high-speed accidents.
