History

I-15 replaced US 395 between San Diego and Temecula. The highway replaced US 66 between San Bernardino and Barstow. The route north of Barstow replaced US 91.

I-15 was initially planned to run from I-10 in San Bernardino along the current I-215 alignment then up through the Cajon Pass and on to Las Vegas, with a distance of within the state. California successfully argued the addition south to San Diego, suggesting that the freeway would connect the major military bases former March AFB and former NAS (now MCAS) Miramar. US 395 was then signed TEMP-15 and the "old" I-15 between Devore
Devore, California

Devore is sometimes considered a small unincorporated area community located where Interstate 15 meets Interstate 215 in San Bernardino County, California, California, it is a area in the city of San Bernardino, California....
 and San Bernardino became I-215.

State Route 31

In 1933, Interstate 15 was defined as Legislative Route 193, running from pre-1964 Legislative Route 43 (present State Route 91) in Corona

The piece south of U.S. Route 60 (Mission Boulevard), running along North Main Street, Hamner Avenue and Milliken Avenue, was state-maintained by 1955, but was not assigned a signed number. This was still the only existing piece in 1963, and had a planned freeway

In the 1964 renumbering
1964 state highway renumbering (California)

In 1963 and 1964, the California Division of Highways implemented a major renumbering of List of State Highway Routes in California. The majority of sign routes - those marked for the public - kept their numbers; the main changes were to the legislative routes, which had their numbers changed to match the sign routes....

 in February 1972 as a realignment of Interstate 15 (the former alignment became Interstate 15E). Legislative changes were made in 1974, eliminating SR 31 (along with State Route 71 south of Corona) in favor of I-15. However, SR 31 continued to be signed - as TEMPORARY Interstate 15 - until present I-15 was finished. (A 1986 map shows state maintenance continuing north past SR 60 to Jurupa Street, where it turned east to I-15.)

Future

Interstate 5

Interstate 5 is the main Interstate Highway System on the West Coast of the United States, paralleling the Pacific Ocean from Canada to Mexico and serving some of the largest cities of that part of the U.S., including Seattle, Tacoma, Portland, Oregon, Sacramento, San Francisco/Oakland, Los Angeles, and San Diego....
 to Interstate 8 in San Diego will be re-designated as part of I-15 once this segment is completely upgraded to Interstate standards.

Most of Interstate 15 is undergoing major improvements from Devore to the Nevada State Line, beginning in 2002 and costing $349 million. This project will improve traffic flow on the heavily traveled highway for those going to and from Las Vegas. Most of the construction will be completed by Winter 2009. Projects include adding truck lanes on hills (39 miles at various locations), repaving of I-15 at various locations, adding exit numbers, renovating and rehabilitating the rest area between Baker

, and moving the agriculture inspection station from Yermo to the Nevada State Line and including a truck weigh station.

As of March 2008, construction is underway to add a northbound truck descending lane and to repave lanes between Bailey Rd. and Yates Well Rd.

There is also construction ongoing (circa spring 2008) to expand traffic lanes in northern San Diego County, including the northward extension (beyond SR 56) of the existing high-occupancy toll
