Montebello, California in the context of "Mission Vieja"

Olympic Boulevard, formerly 10th Street, is a major arterial road in Los Angeles County, California. It stretches from Ocean Avenue at the western end of Santa Monica to East Los Angeles. It runs north of Pico Boulevard and south of Wilshire and Santa Monica boulevards from Santa Monica to downtown Los Angeles.

Like other major Los Angeles streets, Olympic is at least four lanes in width. Unlike other east-west arterial roads such as Wilshire Boulevard, Santa Monica Boulevard, and Sunset Boulevard, it does not cross major attractions and sites and therefore contains far less traffic. While Wilshire crosses through the heart of Los Angeles, Olympic runs through the southern end of principal areas such as West Los Angeles, Westwood, Century City, Beverly Hills, Hancock Park, Koreatown, Westlake and Downtown Los Angeles. Little Ethiopia is east of Fairfax Avenue and Olympic. Proceeding east on Olympic, it breaks off in Downtown LA's Fashion District but continues on from there, passing the southern areas of Boyle Heights, East Los Angeles, Commerce, and Montebello with an eastern terminus in Pico Rivera as a small neighborhood street.
