SR-71: Corona Freeway / Chino Valley Freeway

ca_71_smallCorona Freeway and Expressway, Future Chino Valley Freeway
Runs from I-10 at the Kellogg Hill Interchange (I-10/SR-57/I-210) to SR-91 near Corona.

Highway 71 is a varied route. It starts as a freeway at I-10, then turns into an expressway, then back into a freeway only to go back to an expressway before finally ending onto SR-91. 71 used to go all the way to Hwy 74 near Mountain Center following SR-91, I-15, SR-79, and SR-371. SR-71 also had a different routing through Pomona along Garey Avenue. US 60/70/99  ran along the routing of present-day Route 71 from I-10 to Holt Blvd. US 60 continued south to Holt Blvd. Part of that old highway still remains adjacent and even under the freeway of today. The remaining expressway segments are slated to be upgraded within the next few years.
