State Route 19 (SR 19) is a state highway in the U.S. state of California, running along Lakewood Boulevard and Rosemead Boulevard in the Los Angeles area. An additional "hidden" state highway, State Route 164 (SR 164), is also signed as part of SR 19, despite having a legal description separate from Route 19. The combined route is a north–south four-to-eight lane suburban roadway, lying east of the Long Beach Freeway (Interstate 710) and west of the San Gabriel River Freeway (Interstate 605), and connecting the eastern parts of Long Beach and Pasadena via the Whittier Narrows. Under their legal descriptions, SR 19 runs north to Gallatin Road in Pico Rivera, then SR 164 goes from Gallatin Road to Pasadena. Since 1998, several pieces have been relinquished to local governments, and more transfers are authorized by state law, though some maps and signs may still mark SR 19/164 as continuous through these cities.
