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 only a freeway in San Bernardino and Riverside counties; in Los Angeles County it is only an expressway.

This route is part of the California Freeway and Expressway System[2] and is eligible for the State Scenic Highway System.[3] However, it is not designated as a scenic highway by Caltrans.[4] Other names of this highway include the "Police Officer Daniel T. Fraembs Memorial Highway" (Route 71 in the City of Pomona),[5] and the "Mayor James Thalman and Mayor Michael Wickman Memorial Highway" (Route 71 between Soquel Canyon Parkway & Pine Avenue in Chino Hills).[6]
Beginning at its northern terminus at the Kellogg Interchange complex in San Dimas to a short distance south of Holt Avenue 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.
The original routing of Route 71 according to the 1934 listing was from U.S. 80, now Interstate 8, in San Diego north to U.S. Route 66, now State Route 66, near Claremont via Elsinore and Temecula.[7] The early section of Chino Valley Freeway was made in 1971 from Kellogg Interchange to Pomona Freeway. The section from SR 60 to Riverside Freeway was completed in March 1998.
In September 2008, construction began on the Mission 71 Project, in which Route 71's intersection at Mission Boulevard in Pomona will be reconstucted into a grade-separated, diamond-designed interchange. A bridge is being constructed to allow Mission to pass over Route 71, which will have entrance and exit ramps to Mission. [8]The freeway will be extended south to the current four-way intersection at Ninth Street, where it will resume expressway status to the intersection with Old Pomona Road. According to the Mission 71 Project website, the construction project is expected to take 22 months and should be completed by Fall 2011. [9]
