Interstate 15

Interstate 15 is an interstate highway in the western United States. It goes from San Diego, California just south of Interstate 8 (where it sputters out and becomes California State Route 15) to Sweetgrass, Montana at the Canadian border. North of its juncture with California State Route 91 in the Inland Empire (California), the route follows (roughly) the old US Route 91.

It is possible that this highway may be extended south to Interstate 5 along CA 15 to Barrio Logan, California in the future. Note there are three Interstate 215's - in Inland Empire, California; Las Vegas, Nevada; and Salt Lake City, Utah.
