State Route 60 (California) State Route 60 is an east–west state highway in southern California connecting the Port of Los Angeles region through the Los Angeles Basin and across the San Gabriel Valley to the Inland Empire. The corridor links major arterials such as Interstate 10, Interstate 5, and Interstate 15 while serving population centers including Los Angeles, Pomona, Rialto, and Riverside. The route functions as both an urban freeway and a regional connector for goods movement between the Pacific Coast and interior distribution hubs.
Route description
SR 60 begins at a junction with Interstate 10 in Los Angeles near the East Los Angeles Interchange, proceeding east as the Pomona Freeway through the City of Los Angeles and the East Los Angeles district adjacent to Downtown Los Angeles, Chinatown, and the Los Angeles River. The highway interchanges with Interstate 5, passing near Commerce and Montebello before traversing the foothills of the Puente Hills toward Whittier and La Habra. SR 60 then continues through the San Gabriel Valley to Industry and West Covina, where it intersects with SR 57 and Interstate 605 near Irwindale and the San Gabriel Mountains foothills.
East of the Pomona Freeway section the route becomes the Riverside Freeway as it approaches Pomona and Ontario, intersecting Interstate 15 and providing access to Ontario International Airport. SR 60 continues through Chino, Montclair, and Rialto, joining or paralleling SR 91 and SR 210 in segments before entering Riverside County. The highway skirts Riverside and passes near Moreno Valley and Perris as it climbs the Garnet Hill area toward Beaumont, where it terminates at Interstate 10 near the San Gorgonio Pass and San Bernardino Mountains.
History
The corridor that SR 60 occupies evolved from early wagon roads, trolley routes, and state highway designations that linked the Los Angeles Basin to the Inland Empire during the late 19th and early 20th centuries, contemporaneous with the rise of the Southern Pacific Railroad and the growth of the Port of Los Angeles. Designation and freeway construction accelerated after the Federal-Aid Highway Act of 1956 as part of southern California's postwar expansion tied to the aerospace and logistics sectors, with major segments completed in the 1960s and 1970s. The designation SR 60 replaced earlier legislative route numbers and incorporated alignments of U.S. Route 60 in parts, reflecting changes in the United States Numbered Highway System and the development of parallel interstates such as Interstate 10 and Interstate 15.
Construction of interchanges, widening projects, and managed lanes continued into the late 20th and early 21st centuries to address congestion created by suburbanization in Los Angeles County and Riverside County. Notable projects involved multilevel interchanges with Interstate 605, revisions near the East Los Angeles Interchange, and eastward extensions to meet Interstate 10 in Beaumont. Community responses and environmental review processes engaged agencies such as Caltrans, regional transportation planning organizations like the Southern California Association of Governments, and local jurisdictions including Pomona and Riverside.
Major intersections
SR 60 interchanges with a number of principal highways that are critical for regional connectivity: - Western terminus: Interstate 10 in Los Angeles - Junction with Interstate 5 near Commerce - Interchange with SR 57 near Industry - Junction with Interstate 605 near Irwindale - Interchange with Interstate 15 near Ontario - Connections with SR 71 in Pomona - Junction with SR 91 and proximity to SR 210 - Eastern terminus: Interstate 10 in Beaumont
Future and planned projects
Planned and proposed improvements on SR 60 include lane additions, interchange reconstructions, and operational enhancements to address freight movement tied to the Port of Los Angeles and Port of Long Beach, as well as commuter demand from Los Angeles, Riverside, and San Bernardino County. Regional plans from agencies such as the Riverside County Transportation Commission and the Los Angeles County Metropolitan Transportation Authority consider managed lanes, auxiliary lane projects, and ramp metering coordination with Metrolink corridors and Southern California Regional Rail Authority initiatives. Environmental assessments have involved the California Environmental Quality Act process, with stakeholder engagement from municipalities like Montclair and Perris, freight stakeholders including the BNSF Railway and Union Pacific Railroad, and community groups addressing air quality concerns monitored by the South Coast Air Quality Management District.
Auxiliary routes and related highways
SR 60 interfaces with several related state and federal highways that function as auxiliaries or parallels, including Interstate 10, Interstate 15, SR 57, Interstate 5, SR 71, SR 83, SR 91, and SR 210. Local arterials such as Hacienda Boulevard, Mission Boulevard, and Foothill Boulevard serve as surface-route alternates. Freight and rail corridors like the Southern Pacific Railroad (historical), Union Pacific Railroad, and BNSF Railway run adjacent in places, influencing grade separation and interchange design. Ongoing coordination between Caltrans District 7 and Caltrans District 8 is critical for maintenance, emergency response, and capital improvements.
