State Route 22 (California) is an east–west state highway in Los Angeles County and Orange County in southern California. The route connects Long Beach and the Port of Long Beach area with suburban corridors including Garden Grove, Westminster, and Orange, intersecting several major freeways such as I‑405, I‑605, SR‑57, and SR‑55. It serves commercial, industrial, and commuter traffic across dense metropolitan regions including portions of the Los Angeles metropolitan area.
Route description
SR‑22 begins at a partial interchange with I‑405 near the Long Beach Freeway and the Long Beach Airport, proceeding eastward as a limited-access highway and arterial hybrid along the north edge of the Port of Long Beach complex and the Los Cerritos Wetlands. The highway passes through or near Signal Hill, Los Alamitos, and the Seal Beach National Wildlife Refuge area before entering Orange County municipalities such as Garden Grove, Westminster, Fountain Valley, and Santa Ana. Major interchanges include I‑605 (near the Kellogg Hill corridor), I‑405 spur links, SR‑39 access, SR‑55, and a connection to SR‑57 via adjacent arterial networks. The alignment alternates between freeway segments and at‑grade arterial segments, with local names including the Garden Grove Freeway and portions designated as the Century Freeway corridor near industrial zones and retail centers like Westfield MainPlace and Downtown Santa Ana.
Because SR‑22 traverses dense urban and industrial landscapes, it intersects rail infrastructure including tracks of Union Pacific Railroad and BNSF Railway serving the Port of Long Beach and regional freight terminals. The corridor is part of the California Freeway and Expressway System and a segment of the National Highway System for its importance to national commerce and mobility.
History
The route originated from early 20th‑century state highway planning that connected port facilities and inland communities, with alignments formalized in the 1930s under state legislators and the California Division of Highways (later Caltrans). Postwar suburbanization driven by developments like Lakewood and the expansion of the Port of Los Angeles and Port of Long Beach increased traffic volumes, prompting phased upgrades during the 1950s–1970s tied to interstate and state highway projects such as I‑605 construction and the wider Interstate Highway System impacts.
The Garden Grove Freeway designation and subsequent improvements reflected cooperation between Orange County Transportation Authority initiatives and state funding mechanisms, influenced by regional plans such as the Southern California Association of Governments transportation studies. Environmental reviews addressed impacts to wetlands and cultural resources near sites like the Los Cerritos Wetlands and coordinated with agencies including the U.S. Fish and Wildlife Service. Over decades, interchange modifications and lane additions responded to congestion related to commuter patterns and freight movements serving the Port of Long Beach and retail centers.
Major intersections
Major junctions along SR‑22 include its western terminus at I‑405 near Long Beach Airport, an interchange with I‑605 in the Kellogg Hill area, connections to arterial routes serving Seal Beach and Los Alamitos, and its eastern terminus at SR‑55 in Orange. Other important crossings provide access to SR‑39 corridors, local arterials into Garden Grove and Westminster, and links to regional transit hubs including Metrolink stations and Orange County Transportation Authority bus routes. The highway's role as a connector to the National Highway System underscores its intersectional importance for freight and commuter throughput.
Related routes and designations
Portions of SR‑22 are known locally as the Garden Grove Freeway and carry signage coordinated with Caltrans District 12. The corridor interacts with auxiliary and parallel facilities such as I‑405 and I‑605 and supports truck routes servicing the Port of Long Beach and Ports of Los Angeles and Long Beach complex. SR‑22 has been included in regional planning by entities like the Orange County Transportation Authority and Metro for coordination of freight, transit, and highway improvements. Historic highway maps and legislative route numbers referenced in archives of the California State Legislature document the route's statutory designations and amendments.
Future developments and improvements
Planned and proposed projects focus on congestion relief, safety upgrades, and freight efficiency, involving stakeholders including Caltrans, the Orange County Transportation Authority, local city governments such as Garden Grove and Orange, and federal funding programs administered by the Federal Highway Administration. Proposals have included interchange reconstructions near I‑605 and improvements to ramp geometry and signalized arterials to reduce bottlenecks at portals to the Port of Long Beach and regional shopping centers. Environmental mitigation measures coordinate with agencies such as the California Coastal Commission and U.S. Fish and Wildlife Service where projects affect wetlands and habitat corridors. Future transit integrations under discussion involve enhanced bus rapid transit links operated by Orange County Transportation Authority and potential multimodal connections to Metrolink and Southern California Regional Rail Authority networks to reduce single‑occupant vehicle demand.
