State Route 57 (SR 57), also known as the Orange Freeway, is a north–south state highway in the Greater Los Angeles Area of California. It connects the interchange of Interstate 5 (I-5) and SR 22 near downtown Orange, locally known as the Orange Crush, to the Glendora Curve interchange with I-210 and SR 210 in Glendora. The highway provides a route across several spurs of the Peninsular Ranges, linking the Los Angeles Basin with the Pomona Valley and San Gabriel Valley. A predecessor to this road ran through Brea Canyon by the early 20th century and was added to the state highway system. The freeway was built in stages during the 1950s, one of which included the Brea Canyon Freeway; SR 57 was designated as part of the 1964 state highway renumbering. The final portion of the present-day Orange Freeway was not completed until the early 1970s. The latest piece of SR 57 to be added was formerly part of I-210, after SR 210 was extended to San Bernardino in 1998. An unconstructed extension from Santa Ana south to Huntington Beach remains in the legal definition of Route 57, and has been studied most recently as a toll road above the Santa Ana River.
