State Route 60
Looking west at the Pomona Freeway from the transition ramp that connects Interstate 710 (Long Beach Freeway) north with SR 60 west. - 08/26/2007
California 60 is the Pomona Freeway from I-5/10 east to Interstate 215 and the Moreno Valley Freeway from I-215 east to Interstate 10. The freeway leads from downtown Los Angeles east through Montebello, Diamond Bar, Pomona, Chino, Ontario, Riverside, and Moreno Valley. The route is freeway for its entire length except for an expressway section between Moreno Valley and Interstate 10. In this short stretch, California 60 passes through a narrow badlands section and has a few cross streets before merging with Interstate 10 eastbound. Despite its number, only portions of the freeway near Pomona ever carried the U.S. 60 designation. Sections of the freeway opened after 1964 were designated as California 60.

The 57/60 Confluence Project made improvements in Diamond Bar where California 57 and California 60 converge, including the direct connection ramp for High Occupancy Vehicle (Carpool) traffic. Specific improvements outlined development of collector distributor lanes, traffic separation for the connections to Grand Avenue that eliminated weaving and merging across multiple lanes, and additional lanes. The project (planning, environmental review, design, and construction) was anticipated to continue from 2009 through 2016.

This old sign, which dates back to when California 60 was signed as U.S. 60 and Interstate 10 was also signed as U.S. 70-99, has been covered with green overlays to hide the old U.S. route designations and advise of the simpler California 60 and Interstate 10 designations.
