Why is "California State Route 2" trending?

Wikipedia Overview

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; though some maps mark SR 2 as continuous through the cities of Santa Monica, Los Angeles, Beverly Hills and West Hollywood, control of segments within those cities were relinquished to those local jurisdictions and are thus no longer officially part of the state highway system. The second section of SR 2 runs from US 101 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. Finally, the northeastern portion from I-210 in La Cañada Flintridge to SR 138 is designated as the Angeles Crest Highway.
