California 71 crosses over the Santa Ana River near Prado Dam west of Corona and southeast of Chino Hills. This view shows the bridge as seen from the westbound lanes of California 91. Photo taken 09/28/08.
California 71 is the Chino Valley Freeway between California 91 and California 57 (with connections to Interstate 10). 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/Euclid Avenue and California 91/Riverside Freeway was the last section to be upgraded to freeway standards (aside from a few connecting service roads). The remainder of California 71, between California 60 and California 57, is an older urban expressway. It is unclear when this segment will be upgraded to full freeway standards, as funding is a major concern (some maps erroneously show this short segment as a freeway, but it is actually an at-grade expressway). California 71 is known as the Chino Valley Freeway (it was formerly known as the Corona Expressway, but that name now applies to nearby Interstate 15/Corona Freeway).
California 71/Chino Valley Freeway north
After leaving California 91/Riverside Freeway, northbound California 71/Chino Valley Freeway crosses over the Santa Ana River. Photo taken 01/30/05.
For the first several miles, California 71 is an expressway until the interchange with California 83. Although portions of the highway were only two lanes wide until the mid-2000s, the highway is now four lanes. Prior to the additional lanes, passing lanes were set up along the two-lane section, such as these shown in this photo. A turnoff is located on the north bank of the Santa Ana River for local and utility access. Photo taken 01/30/05.
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 01/30/05.
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 01/30/05.
The first exit along California 71 north is Exit 3, Junction California 83/Euclid Avenue (one mile). This route was a Super Two when the 2002 photo was taken; it has since been widened to four lanes (two in each direction). Photo taken 01/30/05.
Northbound California 71 approaches Exit 3, Junction California 83 (one-half mile). This exit sign confirms that the full freeway will begin shortly. Photo taken 01/30/05.
The next seven exits from California 71 serve the cities of Chino and Chino Hills. Photo taken 01/30/05.
California 71 leaves Riverside County and enters San Bernardino County. At this point, the freeway expands from four lanes to eight lanes plus HOV lanes. Photo taken 01/30/05.
Northbound California 71/Chino Valley Freeway reaches Exit 3, Junction California 83/Euclid Avenue north to Ontario. California 83 is a fairly short north-south state route, connecting California 71 with Chino, Ontario, and Upland.

Northbound California 71 meets Mission Boulevard, which is historic U.S. 60, at this signalized intersection in Pomona. Although some maps show this as a freeway interchange, this is actually a signalized intersection. Photo taken 05/01/02.
After passing through Pomona, northbound California 71 approaches Exit 14, Junction Business Loop I-10/Holt Avenue east to downtown Pomona and Valley Boulevard west to La Puente. Use Valley Boulevard east to Kellogg Drive northwest to California State Polytechnic University - Pomona. Photo taken 07/15/07.
Northbound California 71 reaches Exit 14A, Junction Business Loop I-10/Holt Avenue east and Valley Bouelvard west. The next exit is Exit 15, Junction Interstate 10 east to Los Angeles and California 57 north to San Dimas and Interstate 210. This massive confluence of freeways is known as the Kellogg Interchange due to its location on Kellogg Hill. The older, button-copy signs were removed and replaced in the early 2000s as part of the conversion of the former north-south section of Interstate 210 into California 57. Photos taken 07/15/07 and 05/01/02.
Departing at Exit 14A, a eucalyptus slope lines the offramp to Holt Avenue and Valley Boulevard. Photos taken 07/15/07.
At the end of the offramp to Exit 14A, turn right to follow Junction Business Loop I-10/Holt Avenue east to downtown Pomona. Turn left to follow Valley Boulevard west to CalPoly-Pomona and La Puente. Continue straight to follow Fairplex Drive to the Fairplex. Photo taken 07/15/07.
Use Fairplex Drive north to Interstate 10/San Bernardino Freeway east to San Bernardino and points east. Photo taken 07/15/07.
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.
