Interstate 710
Interstate 710 is a major north–south freeway in Los Angeles County serving the Port of Los Angeles, Long Beach, Commerce, and Alhambra. The freeway functions as a critical freight corridor linking marine terminals at the Port of Los Angeles and Port of Long Beach with inland distribution hubs near I‑10 and SR‑60. Managed by the California Department of Transportation, it intersects with arteries including I‑405, I‑105, and SR‑91.
Route description
Beginning at the docks adjacent to San Pedro and Terminal Island, the route proceeds north through Long Beach, passing near landmarks such as the Long Beach Convention and Entertainment Center and the Port of Long Beach facilities. It continues past Willowbrook and Compton toward the San Gabriel Valley, intersecting SR‑91 near Downey and Norwalk. North of Commerce the corridor skirts Huntington Park and Vernon before terminating at the interchange with I‑10 and SR‑710 stub in Alhambra. The corridor includes complex interchanges with I‑105 near South Los Angeles and meets I‑405 in Long Beach, serving commuter, regional, and heavy truck traffic bound for the Los Angeles Basin and the Inland Empire.
History
The freeway traces its origins to early 20th‑century truck routes serving the Port of Los Angeles and the growth of Long Beach as a shipping center. In the 1950s, the route was incorporated into the Interstate Highway System planning, with federal designation in 1957 and construction phases continuing through the 1960s and 1970s. Major upgrades included the completion of the Long Beach Freeway segment connecting to Downtown Long Beach and later interchange expansions at I‑105 following the Los Angeles International Airport era developments. Environmental reviews in the late 20th century involved agencies such as the California Air Resources Board and the United States Environmental Protection Agency, reflecting concerns raised by communities like Bell Gardens and Maywood.
Controversies and proposed extensions
Proposals to extend the northern stub northeast through the Pasadena and South Pasadena corridor toward I‑210 prompted lengthy disputes involving City of Los Angeles, City of Pasadena, community activists, and labor organizations such as the International Longshore and Warehouse Union. Opposition cited potential impacts on neighborhoods, historic districts including parts of South Pasadena near the Los Angeles River, and sites listed by the National Register of Historic Places. Legal challenges invoked statutes administered by the California Environmental Quality Act and federal permitting overseen by the United States Army Corps of Engineers. Alternatives studied included tunnel options supported by some transportation planners and the expansion of rail freight via projects promoted by the Los Angeles County Metropolitan Transportation Authority and the Southern California Association of Governments.
Traffic, safety, and transportation impact
The corridor is one of the region’s busiest for freight, with heavy concentrations of container trucks serving the Ports of Los Angeles and Long Beach and inland logistics centers in the Inland Empire near Ontario and Rialto. Congestion hotspots occur at interchanges with I‑105 and SR‑91, leading to mitigation projects funded by measures such as the Los Angeles County Measure R and federal grants from the Federal Highway Administration. Air quality and public health studies by the South Coast Air Quality Management District and academic institutions including University of Southern California and California State University, Long Beach have documented diesel particulate exposure in adjacent communities. Safety improvements have included median barrier installation, ramp reconfigurations, and truck lane management; enforcement and technology deployments have involved the California Highway Patrol and pilot programs with the California Air Resources Board for cleaner truck fleets.
Exit list
The freeway’s exits serve a mix of industrial, residential, and commercial zones, including key connections to Pacific Coast Highway, SR‑91, I‑105, I‑405, and terminating junctions at I‑10. Major interchanges provide access to ports, intermodal yards near Commerce, and distribution centers serving Southern California. Full milepost and exit numbering correspond with California Department of Transportation standards.
