This spur becomes a surface arterial at the intersection with South Chestnut Place and the Pike Parking Garage. The first spur splits at the 9th Street interchange, with the left-branching ramps crossing the Shoemaker Bridge over Los Angeles River and becoming West Shoreline Drive as they head to downtown Long Beach, passing the Aquarium of the Pacific and the Long Beach Convention Center among other attractions. Near its southern terminus, I-710 separates into three spur freeways. I-710 then travels roughly north, east of downtown Los Angeles, to its current northern terminus at Valley Boulevard (just north of I-10) in Alhambra and the El Sereno neighborhood of Los Angeles. From there, the Long Beach Freeway follows the course of the Los Angeles River to Atlantic Boulevard at the Bell– Vernon city limits. The southern terminus of the freeway presently signed as I-710 is at Ocean Boulevard in Long Beach. Section 622.1 amends the definition, stating "Route 710 shall also include that portion of the freeway between Route 1 and the northern end of Harbor Scenic Drive, that portion of Harbor Scenic Drive to Ocean Boulevard, that portion of Ocean Boulevard west of its intersection with Harbor Scenic Drive to its junction with Seaside Boulevard, and that portion of Seaside Boulevard from the junction with Ocean Boulevard to Route 47." Section 622 of the California Streets and Highways Code defines Route 710 as "from Route 1 to Route 210 in Pasadena".

Until 1964 it was State Route 15, but it was renumbered to State Route 7 in the 1964 renumbering because of the existence of I-15, and to I-710 in 1983. Prior to 1983, the road was not an Interstate, although it was built to Interstate Highway standards. Legislation passed in 2019 authorizes its relinquishment to the City of Pasadena on or after January 1, 2024.
It remains unsigned, except for onramps onto the stub which are signed as onramps onto I-210 instead of SR 710.
This segment runs from California Boulevard in Pasadena north to its northern terminus at SR 134 and I-210. SR 710 is the designation of the completed portion of the proposed northern extension of the route to Pasadena. South of SR 1 in Long Beach, I-710 is officially part of the Seaside Freeway. South of Atlantic Boulevard at the Bell– Vernon border, I-710 follows the course of the Los Angeles River, rarely wandering more than a few hundred feet from the riverbed. The completed southern segment is signed as I-710 and is officially known as the Long Beach Freeway, and it runs north from Long Beach to Valley Boulevard, just north of I-10 (San Bernardino Freeway), near the boundary between the cities of Alhambra and Los Angeles. Also called the Los Angeles River Freeway prior to November 18, 1954, the highway was initially planned to connect Long Beach and Pasadena, but a gap in the route exists from Alhambra to Pasadena through South Pasadena due to community opposition to its construction.
Route 710, consisting of the non-contiguous segments of State Route 710 ( SR 710) and Interstate 710 ( I-710), is a major north–south state highway and auxiliary Interstate Highway in the Los Angeles metropolitan area of the U.S.
