Interstate 15
It is possible that this highway may be extended south to Interstate 5 along CA 15 to San Diego's Barrio Logan district in the future. Note there are three spurs identified as Interstate 215: in the Inland Empire region of California; in Las Vegas, Nevada; and in Salt Lake City, Utah.
From the junction of Limonite Avenue to the northern junction with the I-215 spur, this freeway is named the Ontario Freeway. From the northern I-215 junction to the Nevada state line, this freeway is called the Mojave Freeway.

Managed Lanes Project- Initated during fall 2003 and will finished late 2007. Portion of CA-56 to Centre City Pkwy (former US 395). More info in "reference" section; See also high occupancy toll.
At the time it was built, the section running through the northwest corner of Arizona (the Virgin River gorge) was the most expensive section (per mile) of the entire interstate system.
The sign for the Zzyzx exit, the alphabetically last place name in the United States, is a well-known landmark along the drive from Los Angeles to Las Vegas on I-15.
