Sunland-Tujunga/th/ is a neighborhood of the city of Los Angeles located by the foothills of the San Gabriel Mountains in the Crescenta Valley. Though Sunland and Tujunga began as separate settlements, they are today linked through a single police station, branch library, neighborhood council, chamber of commerce, City Council district, and high school and various civic organizations. The merging of these communities under a hyphenated name goes back as far as 1928. Sunland-Tujunga contains the highest point of the city, Mount Lukens. The neighborhood lies between the Verdugo Mountains and the San Gabriel Mountains. It is contiguous on the east with La Crescenta-Montrose. Sunland and Tujunga are divided by Mount Gleason Avenue, with Sunland on the west and Tujunga on the east. Mount Lukens within Tujunga is the highest point in Los Angeles at 5,074ft (1,547m). In 1925 there were no sidewalks or curbs in Tujunga, but by 1927 half of the streets had been paved. A state highway ran through the town. Streets within the Sunland and Tuna Canyon annex to Los Angeles were renamed in June 1929. The main east-west road, previously known as Michigan Avenue, became Foothill Boulevard. Other streets were renamed as follows: Los Angeles Street to Apperson Avenue, Sherman Street to Hartranft Avenue, Center Street to Grenoble Avenue, North Street to Wentworth Avenue, Third Street to Woodward Avenue and Hill Street to Hillrose Avenue. Sunset renamed to Commerce St. Manzanita Drive was renamed McGroarty Avenue in honor of John Steven McGroarty, who lived nearby.
