SR-52: San Clemente Canyon Freeway

SR-52
San Clemente Canyon Freeway / Mt Soledad Freeway
Runs from I-5 in Rose Canyon to SR-67 near Santee

Originally planned to run through the bottom of San Clemente Canyon between I-5 and I-805, local opposition forced it to run along the edge of the canyon. This allowed for the creation of Marion Bear Park, named after one of the chief protesters. The freeway had the unique control point of “San Clemente Canyon” until the signs were replaced in the early 2000’s. State 52 also had no surface routing. The first segment of the freeway was built in 1972 and the last completed in 2011.
