State Route 2 (SR 2) is a state highway in the U.S. state of California. It connects the Los Angeles Basin with the San Gabriel Mountains and the Victor Valley in the Mojave Desert. The highway's southwestern end is at the intersection of Centinela Avenue at the Santa Monica-Los Angeles border and its northeastern end is at SR 138 east of Wrightwood. The SR 2 is divided into four segments, and it briefly runs concurrently with U.S. Route 101 (US 101) and Interstate 210 (I-210). The southwestern section of SR 2 runs along a segment of the east–west Santa Monica Boulevard, an old routing of US 66, to US 101 in East Hollywood; the second section runs along segments of both the north–south Alvarado Street and Glendale Boulevard in Echo Park; the third section to I-210 in Glendale is known as the north–south Glendale Freeway; and the northeastern portion from I-210 in La Cañada Flintridge to SR 138 is designated as the Angeles Crest Highway. Route description SR 2 is known as the Angeles Crest Scenic Byway, a National Forest Scenic Byway, from SR 2's east junction with I-210 in La Cañada Flintridge to the Los Angeles–San Bernardino county line. The Big Pines Highway is routed along SR 2 from County Route N4 (CR N4, the northwest continuation of the designation) in Big Pines to the Los Angeles–San Bernardino county line. SR 2 is part of the California Freeway and Expressway System, and except for much of the mountain portion is part of the National Highway System, a network of highways that are considered essential to the country's economy, defense, and mobility by the Federal Highway Administration. SR 2 is eligible to be included in the State Scenic Highway System; however, only the portion of SR 2 from a point northeast of the I-210 interchange to the San Bernardino County line is actually designated as a scenic highway by the California Department of Transportation (Caltrans), meaning that it is a substantial section of highway passing through a "memorable landscape" with no "visual intrusions", where the potential designation has gained popular favor with the community. The California Legislature has relinquished state control of various segments of SR 2 in Santa Monica, Los Angeles, Beverly Hills and West Hollywood, and turned them over to local control.
