Orange Freeway

History

Then, 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 I-210. This became part of the proposed Temescal Freeway, later the Corona Freeway; a southerly extension of the Orange Freeway to Legislative Route 60 (SR 1) near Huntington Beach was added in 1959 as Route 273. Also in 1959, the legislature created Route 272, extending the line of the Orange Freeway north from the Pomona Freeway to the Temescal Freeway, completing the proposed freeway corridor that is now SR 57. When the entire route, except Route 240 which was still part of I-210, was redesignated SR 57 in the 1964 renumbering, none of these proposed freeways had been built; the only constructed segment was the old surface road from Fullerton towards Pomona. The part 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).
