California 60

This view of California 60/Pomona Freeway looking west is taken from the transition ramp that connects Interstate 710/Long Beach Freeway north with California 60 west. Photo taken 08/26/07.

Routing

California 60 is the Pomona Freeway from Interstate 5/10 east to Interstate 215 and the Moreno Valley Freeway from Interstate 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.

Planned Improvements

Ongoing improvements are underway in Diamond Bar at the California 57 and California 60 merge, including the direct connection ramp for High Occupancy Vehicle (Carpool) traffic. Specific improvements include development of collector/distributor lanes, traffic separation for the connections to Grand Avenue that eliminate weaving and merging across multiple lanes, and add the number of lanes. The project (planning, environmental review, design, and construction) is expected to continue from 2009 through 2016. For more information, visit the 57/60 Confluence Project web page.
