Route 60 was provisionally signed as a U.S. Highway since the designation would guide motorists from Los Angeles to Arizona without a completed freeway for I-10; when all of Route 10 was upgraded to a freeway, the U.S. Highway designation disappeared. At least two California highway signs managed to be overlooked for many years afterward. Along eastbound I-10 at the eastern end of the San Gorgonio Pass, US 60 was co-signed with I-10 on the eastbound overhead signage with Indio as the control city at the junction with SR 111. The signage remained as late as 1979 and had appeared in early scenes of the 1980 movie American Gigolo where Julian Kay (played by Richard Gere) is en route to Palm Springs on a "substitute" assignment. Replacement overhead signs now have only I-10 with "Indio, other Desert Cities" as the control cities. Another sign on Hess Boulevard at SR 62 in the unincorporated town of Morongo Valley pointed not to I-10, but to US 60 (with evidence of the sign having pointed to both US 70 and US 99 as well) stood through the early 2000s; it has since been removed. The stretch of SR 60 along the Moreno Valley Freeway made national headlines in April 2004, when five-year-old Ruby Bustamante of Indio and her 26-year-old mother, Norma, were reported missing. Their car had left the road, apparently unwitnessed, between the gap in two guard rails on April 4. It then crashed underneath a tree in a deep ravine. Though Mrs. Bustamante died, presumably at the moment of impact, Ruby survived on her own for ten days on cups of uncooked Top Ramen noodles and bottles of Gatorade which were in the car. In 1998, the HOV lanes between SR 57 and I-15 opened. In 2005, construction of an HOV lane started between I-605 and Redlands Boulevard in two phases. The construction was finished in 2010 from I-605 to SR 57, and in 2008 from I-15 to Redlands Boulevard. The Grand Avenue (exit 24B) interchange went through some significant construction during this period, which included adding a direct HOV connector to SR 57 and an alternate route for SR 60 west to exit Brea Canyon Road (exit 23). There are no current plans to construct the HOV lanes from I-605 to the East Los Angeles Interchange or Redlands Boulevard to I-10. On December 14, 2011, a tanker truck carrying of
