Route 52 is a freeway for its entire length, and bears the official name "Mount Soledad Freeway".State Route 52 is part of the California Freeway and Expressway System and is eligible for the State Scenic Highway System. However, it is not a scenic highway as designated by Caltrans.SR 52 begins just west of I-5 as La Jolla Parkway. The road becomes a freeway as it intersects with I-5 before entering San Clemente Canyon, designated as Marian Bear Memorial Natural Park. After a few exits, SR 52 interchanges with I-805 before exiting the canyon and travelling along the southern edge of MCAS Miramar.
