State Route 71 (SR 71) is the Chino Valley Freeway, formerly the Corona Expressway and before then the Temescal Freeway, a freeway/highway of about 15 miles (24 km) in length located entirely within Southern California, United States. Contrary to its name, this highway is a limited-access freeway in San Bernardino and Riverside counties; in Los Angeles County it is only an expressway. ==Route description== This route is part of the California Freeway and Expressway System〔(CA Codes (shc:250-257) )〕 and is eligible for the State Scenic Highway System.〔(CA Codes (shc:260-284) )〕 However, it is not designated as a scenic highway by Caltrans. Other names of this highway include the "Police Officer Daniel T. Fraembs Memorial Highway" (Route 71 in the City of Pomona), and the "Mayor James Thalman and Mayor Michael Wickman Memorial Highway" (Route 71 between Soquel Canyon Parkway & Pine Avenue in Chino Hills).〔(Route 71 Memorial Highway One Step Closer to Completion )〕 Beginning at its northern terminus at the Kellogg Interchange complex in San Dimas to a short distance south of Mission Boulevard in Pomona, it is a four-lane freeway. From that point and through most of Pomona, it is a four-lane expressway with at-grade intersections with other, 'regular' streets. All are signalized except for Phillips Drive. Just north of the Rio Rancho Road exit, all aspects of the highway 'upgrade' to freeway standards in its alignment, lane width, pavement, barriers, access, etc. The freeway portion of the route ends at the San Bernardino/Riverside County line, where it reverts to a divided four-lane expressway to its terminus at its junction with the Riverside Freeway (SR 91) in Corona. The section of highway between Chino and Corona is notorious for thick winter fogs at dawn and dusk, resulting in many automobile collisions when drivers fail to slow down despite reduced visibility. Residents of Los Serranos (now Chino Hills) recall being awakened by sounds of crinkling bumpers, fenders and headlights. As this freeway/expressway serves as an important diagonally aligned (northwest-southeast) commuter traffic corridor between the cities in the Pomona Valley (eastern Los Angeles County) and the cities of western Riverside County, it is heavily travelled and is used as an alternative to the Orange Freeway, State Route 57 (SR 57) located to the west and the Ontario Freeway, Interstate 15 (I-15) located to the east. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「California State Route 71」の詳細全文を読む スポンサード リンク
