CA State Route 110

CA State Route 110

California State Route 110 is a state highway in California linking the Port of Los Angeles at San Pedro with the central business district of Los Angeles and continuing north to Pasadena. The route combines a scenic waterfront expressway on the Terminal Island approach with a historic elevated freeway through downtown, and a landscaped freeway segment that ascends into the San Gabriel Valley. It serves freight, commuter, and tourist traffic between major nodes such as the Port of Los Angeles, Los Angeles International Airport, downtown Civic Center, and Old Pasadena.

Route description

The southern terminus begins at the San Pedro Bay waterfront near Port of Los Angeles facilities and the USS Iowa museum ship moored in Berth 87. The highway parallels the Los Angeles Harbor and interchanges with arterial routes serving Harbor City, Los Angeles and Wilmington, connecting to the Harbor Freeway logistics corridors that link to I-405 and SR 1. Moving northward, the route crosses the Los Angeles River near the Washington Boulevard Bridge and merges into the historic elevated structure adjacent to landmarks such as the Los Angeles Memorial Coliseum, University of Southern California, and the Bunker Hill district. In downtown, the freeway provides access to Grand Avenue, the Los Angeles Convention Center, and the Staples Center sports complex via interchanges with I-10 and surface streets tied to the Los Angeles Metro Rail system. North of downtown the roadway becomes the landscaped Arroyo Seco Parkway, passing through the Lincoln Heights and Highland Park corridors and paralleling the Arroyo Seco watercourse toward South Pasadena and terminating near Pasadena close to Colorado Boulevard and the Rose Bowl Stadium.

History

The alignment originated from early 20th-century parkway planning connected to the Good Roads Movement and automobile tourism trends championed by figures like Carl G. Fisher; the northern portion, the Arroyo Seco Parkway, opened in 1940 as one of the United States' first limited-access parkways, designed by planners associated with the Metropolitan Water District of Southern California and landscape architects influenced by the Olmsted Brothers. The elevated downtown freeway segments were constructed during postwar freeway expansion overseen by agencies including the California Division of Highways and the Los Angeles County Metropolitan Transportation Authority. The route’s southern extension to the harbor evolved with port expansion initiatives tied to policies of the Port of Los Angeles Board of Harbor Commissioners and federal maritime programs such as those implemented during World War II to improve access to naval and merchant shipping facilities. Major seismic retrofits followed the 1971 San Fernando earthquake and policy shifts after the 1994 Northridge earthquake, prompting structural upgrades influenced by standards from the Federal Highway Administration and state seismic safety legislation. Historic preservation efforts have involved the National Park Service and the California Office of Historic Preservation regarding the Arroyo Seco Parkway, which has been designated as a National Scenic Byway and listed on the National Register of Historic Places.

Major intersections

The route intersects with several principal arteries and facilities that support regional movement and freight flows. Southern terminus connections include local access to Harbor Freeway, stakeholders at the Port of Los Angeles, and arterial links serving Terminal Island Freeway. Mid-route interchanges provide connections to I-405 via feeder routes, junctions with I-10 and surface corridors servicing the Los Angeles Convention Center and Financial District. Key downtown crosspoints include ramps to US 101 and interfaces with municipal streets near Union Station and Grand Central Market. Northward, the freeway merges near Figueroa Street Bridge and intersects parkway connectors at Arroyo Seco Parkway entry points, terminating near arterial connections to Colorado Boulevard and local routes that serve Old Pasadena and the Caltech vicinity.

Related highways and designations

The route historically and functionally connects with several named facilities and highway designations. The southern stretch is often discussed alongside the Harbor Freeway, while the central elevated section is sometimes grouped with the Pasadena Freeway nomenclature for the northern Arroyo Seco Parkway. Administrative relationships tie the corridor to statewide networks such as Interstate Highway System connectors and freight-designated corridors managed in coordination with the California Department of Transportation and regional planning bodies like the Southern California Association of Governments. Designations of historical significance have prompted collaboration with the National Trust for Historic Preservation and local preservation commissions including the Los Angeles Conservancy.

Future developments and projects

Planned and proposed interventions address seismic resilience, multimodal integration, and freight efficiency. Ongoing capital programs involve seismic retrofit projects coordinated with the California Seismic Safety Commission and funding mechanisms administered through California State Transportation Agency grants and federal infrastructure packages associated with the Infrastructure Investment and Jobs Act. Regional mobility initiatives propose enhanced connections to the Los Angeles Metro Rail and bus rapid transit projects overseen by Metro, with stakeholder engagement from the Port of Los Angeles and local city governments including Los Angeles City Council. Environmental reviews have engaged agencies like the California Environmental Protection Agency and community organizations such as the Los Angeles Conservancy to balance historic preservation of the Arroyo Seco Parkway with modernization. Freight movement strategies coordinate with the San Pedro Bay Ports Clean Air Action Plan and logistics planning by the Port of Long Beach and regional shipping firms, while transit-oriented development concepts around corridor nodes involve partners including Metro Local and municipal redevelopment agencies.
