Interstate 710 (I-710), is a state highway in the Los Angeles area of the U.S. state of California, built to Interstate Highway standards. State Route 710 (SR 710) is the completed portion of the proposed northern extension of the route to Pasadena. I-710 is a north–south auxiliary Interstate freeway running for 23 miles (37 km) through Los Angeles County. Officially known as the Long Beach Freeway, 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. South of I-5, I-710 follows the course of the Los Angeles River, rarely wandering more than a few hundred feet from the riverbed. South of SR 1 in Long Beach, I-710 is officially part of the Seaside Freeway.
