California 71 is the Chino Valley/Corona Freeway. It has slowly been upgraded through the 1990s and 2000s into a freeway, starting at Philadelphia Street in Pomona (just north of California 60) and continuing south to California 91. The section of freeway between California 83 and California 91 (Riverside Freeway) is currently under construction. The remainder of California 71, between Interstate 210 and California 60, is an older urban expressway. It is unclear if this segment will be upgraded to full freeway standards. (Don't be fooled by maps saying that California 71 is a full freeway through Pomona, because it is not!) Notably, California 71 carries the Corona Freeway moniker from its old alignment, when it used to continue southeast along modern Interstate 15 to Temecula. Interstate 15 from California 91 to Interstate 215 is known as the Corona Freeway.
California 71 North
After leaving California 91, northbound California 71 is an expressway until reaching Junction California 83. Although portions of the highway are only two lanes wide, the highway opens up to include passing lanes, such as in this photo. Photo taken 05/01/02.
Through this stretch of two to three-lane highway, signs such as this one along northbound indicate that the divided highway (and freeway) are not too far away. This section of highway is slated to become a full freeway; the lanes currently in use will become the northbound California 71 travel lanes. Photo taken 05/01/02.
Even after the sign promising more than just a single lane in each direction, there is a good amount of Super Two (access controlled, median barrier with only two lanes of travel) highway before reaching the freeway. Photo taken 05/01/02.

Northbound California 71 approaching California 83, one-half mile. This exit sign confirms that the full freeway will begin shortly. Photo taken 05/01/02.
Upon leaving Riverside County and entering San Bernardino County, northbound California 71 opens up into a full freeway. The first exit on this freeway is northbound California 83, just ahead. Photo taken 05/01/02.

California 71 is a very new freeway through Chino, as evidenced by the signage, high occupancy vehicle lanes, and newer-looking concrete. This picture shows northbound California 71 approaching westbound California 142 (Chino Hills Parkway/Carbon Canyon Road), one mile, in Chino. Photo taken 05/01/02.
Northbound California 71 approaching westbound California 142 (Chino Hills Parkway/Carbon Canyon Road), one-quarter mile, in Chino. This exit marks the eastern terminus of California 142. California 142 ends at Junction California 90 in Brea in Orange County. Somewhat surprisingly, much of this state highway is rural in character. Photo taken 05/01/02.

Northbound California 71 at Mission Boulevard, which is historic U.S. 60, in Pomona. Although some maps show this as a freeway interchange, this is actually a signalized intersection. Photo taken 05/01/02.
Northbound California 71 approaching Junction Interstate 10 and Interstate 210, the Kellogg Interchange. These are some very old, button-copy signs. Photo taken 05/01/02.
Through this stack interchange, California 71 high above Interstate 10, as it approaches its merge with Interstate 210. These pictures show a progression of signage of the exit for Interstate 10, followed by the change from northbound California 71 into westbound Interstate 210. There is no end shield present on this ramp. Photo taken 05/01/02.
Interstate 210 is no longer signed on the Orange Freeway; it is now considered part of California 57. As a result, these signs have been modified. Photo taken 05/01/02.
Even though some maps do not show it, there is a direct connection from northbound California 71 onto northbound California 57 (formerly westbound Interstate 210). The transition ramp crosses over Interstate 10, merges with the transition ramp from westbound Interstate 10 to westbound Interstate 210, and finally merges with incoming California 57 (Orange Freeway) from the south. Photo taken 05/01/02.
After merging with traffic from westbound Interstate 10, California 71 merges into California 57 northbound. Photo taken 05/01/02.
