California State Route 52 is a state highway in San Diego County, California, that extends from La Jolla Parkway at Interstate 5 (I-5) in La Jolla, San Diego, to SR 67 in Santee. A freeway for its entire length, it serves as a major east–west route through the northern part of the city of San Diego and connects the major north–south freeways of the county. SR 52 passes north of the Rose Canyon Fault before traversing Marine Corps Air Station Miramar (MCAS Miramar). East of Santo Road and west of SR 125, the highway goes through Mission Trails Regional Park, a large open preserve. Plans for a route between La Jolla and Santee date from 1959, and SR 52 was officially designated in the 1964 state highway renumbering. Construction of the freeway east of Santo Road encountered delays from environmentalists over the endangered Least Bell's Vireo, a songbird that faced habitat destruction, as well as those concerned with the destruction of homes and businesses. The extension to Mission Gorge Road opened in 1993, but funding issues delayed the completion of the entire route to Santee until 2011, more than fifty years after construction began.
