California State Route 60
State Route 60 (SR 60) is an east–west state highway in the U.S. state of California. It serves the cities and communities on the eastern side of the Los Angeles metropolitan area and runs along the south side of the San Gabriel Valley. It functions as a bypass route of Interstate 10 (I-10) through the area between the East Los Angeles Interchange in Los Angeles and Beaumont. SR 60 provides a route across several spurs of the Peninsular Ranges, linking the Los Angeles Basin with the Pomona Valley and San Gabriel Valley. The highway also runs concurrently with SR 57 and I-215. Portions of SR 60 are designated as either the Pomona Freeway or the Moreno Valley Freeway.

Future[edit]
Construction on the SR 57/SR 60 Interchange Improvements Project in the area around the SR 57/SR 60 overlap began in 2023 and is scheduled to be completed in 2028. The project will add an eastbound bypass lane between SR 57 southbound and Grand Avenue and between SR 57 northbound and Diamond Bar Boulevard. In addition, the Grand Avenue bridge is planned to be replaced with a wider bridge, and the eastbound off ramp will be redesigned. This is to affect the Diamond Bar Golf Course, which has been closed since 2021 to accommodate the freeway expansion.[19] The widening of SR 60 westbound has already been completed. The westbound freeway previously went through a major widening in 2006 and the Grand Avenue/SR 60 westbound interchange had further improvements finished in 2019.
The I-605 Corridor Improvement Project includes plans to reconstruct the SR 60/I-605 interchange. As of January 2024, the project is still going through the approval process.[20]
A groundbreaking ceremony was held for the future Potrero Boulevard interchange near the Jack Rabbit Trail exit of SR 60 on February 1, 2018. It is planned to be Exit 75.[21][22] There are also plans to convert SR 60 from the Jack Rabbit trail exit to its eastern terminus (I-10) to a full freeway. If this segment is complete, the entire route will be up to Interstate standards. These plans are still only in the environmental phase and have not been approved yet.
