Azusa, CA

Foothill Boulevard crosses Azusa below the San Gabriel Mountains along the city's historic Route 66 corridor. Metro's A Line runs close by, giving the city one station beside the historic Santa Fe depot and civic center and another at the eastern edge near APU and Citrus College. Passenger rail returned in March 2016, and Metro incorporated the former Gold Line into the A Line in 2023. The line extended east to North Pomona in 2025 and also runs through Pasadena, downtown Los Angeles, and onward to Long Beach. As of 2026, the full route covered 57.7 miles and 48 stations. Older storefronts, civic buildings, college activity, and the two station areas share this east-west path. Azusa Pacific University gives the eastern side a distinct daily calendar.

Founded in 1899, APU now operates a comprehensive university on over 100 acres divided into East and West campuses near Citrus Avenue and Alosta Avenue. As of 2026, APU held a Carnegie Research 2 classification. Academic buildings, residence halls, libraries, athletics, and performance spaces bring class schedules and campus events into the surrounding district. Citrus College sits nearby, adding another large educational campus at the eastern city line. The West End contains industrial districts, while shops and services line Foothill Boulevard and Azusa Avenue. Across this compact city, education is most visible in the east, industry toward the west, and municipal and commercial activity near downtown in between. The city's name reaches much farther back than the rail corridor.

Azusa's municipal history traces it to Asuksa-nga, a Gabrieleno community in the upper San Gabriel Valley. In 1841, Luis Arenas received the Rancho El Susa land grant, and in 1844 he sold it to Henry Dalton, who developed a mill, vineyard, and other agricultural operations. A school built from logs and brush in 1868 became the first public school in the upper San Gabriel Valley. The present town was laid out in 1887 and incorporated on December 29, 1898. Route 66 later carried another period of growth along Foothill Boulevard, leaving a transportation history that now overlaps with the modern light-rail line. Azusa covers just over nine square miles at the foot of the San Gabriel Mountains, so the mountain wall is a constant presence north of the street grid.

Roads through the city lead toward San Gabriel Canyon and recreation sites in the San Gabriel Mountains National Monument, while most urban activity remains along the foothill corridor. The Civic Auditorium, Memorial Park Recreation Center, university campuses, and downtown station area give local programs and events several settings across the city. As of August 2026, library service was operating at the former Slauson Middle School campus while the city renovated its main building. The two A Line stops still provide the simplest map of the city: one beside the old Santa Fe depot and civic center, the other beside the campuses where Azusa meets Citrus College.
