California State Route 57 Totally Explained

Everything about Orange Freeway totally explained

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.

Route description

State Route 57 begins at the Orange Crush interchange near downtown Orange, where it meets the northwest-southeast Santa Ana Freeway (I-5) and the east-west Garden Grove Freeway (SR 22). The interchange, long considered a major bottleneck, was rebuilt in the 1990s and 2000s. The freeway heads north from the junction and soon crosses to the west side of the Santa Ana River, continuing north through suburban portions of Anaheim, where it meets the Riverside Freeway (SR 91). As it crosses Imperial Highway (SR 90), SR 57 enters more rugged terrain, soon climbing through Brea Canyon, the gap between the Chino Hills and Puente Hills. Near its summit, the highway curves north out of the Brea Canyon, and descends slightly to a junction with the Pomona Freeway (SR 60) in Diamond Bar, right on the edge of the San Gabriel Valley.
A short overlap carries SR 57 traffic on the outside of SR 60. The two routes head northeast through an arm of the San Gabriel Valley; after they split, SR 57 ascends slightly and then descends through the edge of the Puente Hills and into the west end of the Pomona Valley. Here it meets the San Bernardino Freeway (I-10) and Chino Valley Freeway (SR 71) at the four-level Kellogg Hill Interchange. In the north haly of that interchange, SR 57 enters the San Jose Hills, climbing to its highest elevation before descending back into the connected San Gabriel-Pomona Valleys and ending at the Glendora Curve interchange with the Foothill Freeway (I-210/SR 210) in Glendora.

History

The road through Brea Canyon was oiled dirt by the late 1910s, providing a good connection across a spur of the Peninsular Ranges between the Los Angeles Basin and Pomona Valley. This road left the main coast highway (Harbor Boulevard) at Fullerton and followed the present Brea Boulevard and Brea Canyon Road, merging with the Valley Boulevard from Los Angeles near Walnut and continuing east to Pomona via Valley and Pomona Boulevards. Los Angeles County paved the road in concrete in early 1923, and in 1931 it was added to the state highway system as a branch of Route 19. Route 19 until then connected Route 9 near Claremont with Riverside, following Garey Avenue and Mission Boulevard through Pomona.
   The state built a bypass of the Valley Boulevard portion of the route in the early-to-mid 1930s, leaving the old road near Diamond Bar and heading northeast through the foothills, along the present freeway alignment and Mission Boulevard. To the south, the legislature added then-unrelated Route 180 along State College Boulevard in 1933, connecting Route 2 (I-5) near the Santa Ana River with Route 175 (Orangethorpe Avenue, later replaced by SR 91) near Placentia. By 1955, a Brea Canyon Freeway was proposed to begin at the Santa Ana Freeway (I-5) near La Veta Avenue in Santa Ana and head north, paralleling Routes 180 and 19 to Pomona. (The portion northeast of Diamond Bar into Pomona soon became part of the planned Pomona Freeway, and the name of the remainder was changed to Orange Freeway.) The state legislature changed the definition of Route 19 to reflect this in 1957 by moving its south end to Santa Ana.
   Also in 1957, the northernmost part of present SR 57 was added to the state highway system as part of Route 240, which the legislature designated along the route planned for Interstate 210. This became part of the proposed Temescal Freeway (later Corona Freeway); a southerly extension of the Orange Freeway At the time of the 1964 renumbering, when the entire route (except Route 240, which was still part of I-210) was redesignated Route 57, none of these proposed freeways had been built; the only constructed portion was the old surface road from Fullerton towards Pomona. (The portion of old Route 19 east of Route 272 became part of SR 60.) As part of the same renumbering, Route 180 on State College Boulevard became Route 250, which was amended the next year to provide for its deletion once that portion of the SR 57 freeway was completed (between I-5 and SR 91). A groundbreaking ceremony was held in Placentia on January 30, 1967 to begin construction of the Orange Freeway. The first portion was dedicated on May 16, 1969 and opened soon after, extending north from the Riverside Freeway (SR 91) to Nutwood Avenue. Over the next few years, the freeway was completed from SR 91 north to I-10, and I-210 was built north to the present end of SR 57; the Pomona Freeway (SR 60), which overlaps it through Diamond Bar, was constructed at the same time. and the four-level Kellogg Hill Interchange at I-10, dedicated May 1, 1972 and opened soon after. Finally, the Orange Freeway was extended south from SR 91 to I-5 in the mid-1970s,). With the extension of Route 210 around San Bernardino in 1998, the former easternmost piece of I-210 to the Kellogg Hill Interchange instead became a northerly extension of SR 57, though it remains officially part of the Interstate Highway System.
   The southerly extension to Huntington Beach remains unconstructed. The most recent plans were for a toll road elevated above the Santa Ana River rather than through existing neighborhoods, only extending south to the San Diego Freeway (I-405) in Costa Mesa with connections to the Corona del Mar Freeway (SR 73). The extension was most recently considered as two 11.2-mile (18.0 km) two-lane viaducts, costing $950 million; the toll road franchise expired in January 2001.
