State Route 52 (SR 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. It is a freeway for its entire length and serves as a major east–west route through the northern part of the city of San Diego. The road connects the major north–south freeways of the county, including I-5, I-805, SR 163, I-15, SR 125, and SR 67. 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. SR 52 is also known as the Soledad Freeway and the San Clemente Canyon Freeway.
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 began in 1966 at the I-5 interchange with Ardath Road leading to La Jolla. It continued with the building of San Clemente Canyon Road, which was later widened to become SR 52. The freeway was completed east to I-805 in 1970, and was built in two stages from there to Santo Road east of I-15; the last phase was completed in 1988.
The freeway east of Santo Road encountered delays from environmentalists over the endangered least Bell's vireo, a songbird which faced habitat destruction, as well as those concerned with the destruction of homes and businesses for the freeway right-of-way. The extension to Mission Gorge Road opened in 1993, and SR 52 was completed to SR 125 in 1998. Funding issues delayed the completion of the entire route until 2011, more than fifty years after construction began; until then, the city of Santee faced traffic snarls. A widening project was completed in 2007 between Santo Road and Mast Boulevard; further expansion has been put on hold due to state budget concerns.
==Route description==

SR 52 begins just west of I-5 at the eastern end of La Jolla Parkway. Before entering San Clemente Canyon, the road becomes a freeway as it intersects I-5. The canyon is part of Marian Bear Natural Park.〔 The freeway runs north of the Rose Canyon Fault, composed of Late Cretaceous rock estimated to be 90 million years old, and Mount Soledad.〔 Following exits with Clairemont Mesa Boulevard / Regents Road and Genesee Avenue, SR 52 intersects I-805 before exiting the canyon and traveling along the southern edge of the MCAS Miramar military base.〔
From I-805 to SR 163, the highway goes through an area with visible Pliocene sedimentary rocks estimated to be 10 million years old.〔 After passing the Miramar Recycling Center and an interchange with Convoy Street, SR 52 intersects SR 163, a freeway heading towards downtown San Diego.〔 SR 52 intersects Kearny Villa Road before an interchange with I-15. A collector-distributor road serves these three interchanges.〔
After this interchange, the freeway leaves the edge of the military base and enters the San Diego neighborhood of Tierrasanta, where there is a junction with Santo Road, before traversing Mission Trails Regional Park, an open space preserve, for a few miles.〔 The freeway ascends to Mission Trails Pass, north of the summit of Fortuna Mountain. The mountain is part of the Peninsular Range; the highway cuts through Eocene rocks estimated to be 50 million years old and marine fossils. The road on the eastern side of the mountain is carved out of "igneous granitic rocks" that are thought to be 150 million years old, an unusual formation compared to the Eocene layer.
A dedicated two-way bicycle path exists on the northern side of the roadway between Santo Road and Mast Boulevard, with access possible from both terminii. East of the Mast Boulevard interchange, SR 52 crosses and begins to parallel the San Diego River. The freeway enters the city of Santee, where SR 52 was built alongside Mission Gorge Road. SR 52 intersects the northern end of SR 125, where SR 52 traffic can exit south onto SR 125. The freeway continues east through Santee, with interchanges at Fanita Drive, Cuyamaca Street, and Magnolia Avenue, before it comes to an end at SR 67.
SR 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 because it has not successfully been through the nomination process. SR 52 is not part of the National Highway System, a network of roads that are important to the country's economy, defense, and mobility. The entire route is known as both the Soledad Freeway and the San Clemente Canyon Freeway. In 2013, SR 52 had an annual average daily traffic (AADT) of 69,000 at the eastern terminus with SR 67, and 103,000 between Convoy Street and SR 163, the lowest and the highest AADT for the highway, respectively.
