The entire route was deleted from the California Freeway and Expressway System in 2000, with the remaining portion of SR 42 being relinquished to local jurisdictions in that year. The direct interchange with I-5 was later demolished in 2013 in favor widening that portion of the Interstate. However, some SR 42 signs may still remain along the route.

I-10 is also known colloquially as "the 10" to Southern California residents (See also California English § Freeways).

After passenger service ended, much of the route was retained for freight service, eventually becoming the Union Pacific La Habra Subdivision.
