Interstate 710 (I-710) and State Route 710 (SR 710) are two highways in Los Angeles County, California. They are not connected, but they both go in the same north-south direction in line with each other. The I-710 (also called the Long Beach Freeway) goes from the Port of Los Angeles north along the Los Angeles River to East Los Angeles. Here, it continues north away from the river before ending near to the Interstate 10 at Alhambra. State Route 710 is short. It starts in Pasadena and goes north where it joins the Interstate 210. Together, these are about long.
