The road is the main connector from the San Fernando Valley and points north to the San Gabriel Valley and points east. The future I-710 dead-ends at California Blvd and is signed as SR 710. Residents of South Pasadena have blocked efforts to extend I-710 north to California Boulevard from its current end at Valley Boulevard north of I-10 near the Alhambra/Los Angeles city limit. Signs on SR 134 and I-210 refer to the SR 710 stub in Pasadena as TO SR 110, because exiting left from the SR 710 stub onto California Blvd and turning right on Arroyo Parkway leads directly to SR 110, which is Pasadena's only direct freeway link to Downtown Los Angeles.
