State Route 57 (SR 57), also known as the Orange Freeway, is a major north-south state highway in the Greater Los Angeles Area of the U.S. state of California. It connects the interchange of I-5 and SR 22 near downtown Orange, locally known as the Orange Crush, with 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. It is eligible for the State Scenic Highway System through Brea Canyon, between SR 90 and SR 60, and the entire route is in the California Freeway and Expressway System (and is a freeway where built). 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.
