Angeles Crest Highway, Mountain highway in Los Angeles County and San Bernardino County, United States
Angeles Crest Highway stretches 66 miles through the San Gabriel Mountains, connecting La Cañada Flintridge to State Route 138 near Wrightwood.
The construction of this mountain road began in 1929 with prison labor from Camp 37, paused during World War II, and reached completion in 1956.
The road provides access to Mountain High ski area, Mount Wilson Observatory, and numerous trails within Angeles National Forest.
Sections of the highway close during winter months between Islip Saddle and Vincent Gap due to snow, rockfall hazards, and landslides.
The road reaches 7,903 feet at Dawson Saddle, making it one of the highest paved routes in Southern California.
