In the U.S. state of California, Interstate 15 is a major north south route through the San Bernardino, Riverside, and San Diego Counties, and it has a length of in the state. It is a major thoroughfare for traffic between Southern California and Las Vegas, Nevada, as well as points beyond. It is also the main route for traffic between San Diego and the Inland Empire.

Interstate 15 has portions designated as either the Escondido Freeway, Avocado Highway, Temecula Valley Freeway, Ontario Freeway, Barstow Freeway, or Mojave Freeway.

Route description

Interstate 15 is part of the California Freeway and Expressway System,[1] and it is eligible for designation as a state highway within the State Scenic Highway System;[2] however the state transportation authority, Caltrans, has not done so.[3] There are various local names for the highway, such as the Escondido Freeway between San Diego and Escondido. between SR 163 and Pomerado Road/Miramar Road is known as the Semper Fi Highway in recognition of the nearby Marine Corps Air Station Miramar.[4] North of the Escondido city limits it is known as the Avocado Highway, whose designation ends upon entering Temecula. There are other local names as noted below.

Heading northward, I-15 currently begins at Interstate 8, at the same place that its continuation, State Route 15, begins its southward journey. goes through Mission Valley and intersects with State Route 52, before merging with State Route 163. After traversing the Marine Corps Air Station Miramar, I-15 comes into Rancho Penasquitos, where it intersects with the end of State Route 56. Northward, the route crosses Lake Hodges inside the upper San Diego city limits. I-15 continues north into Escondido, where it interchanges with State Route 78. There are high-occupancy toll lanes in the center of I-15 from State Route 163 to State Route 78.[5]

North of Escondido, I-15 goes through hilly terrain and farmland, descending to the town of Fallbrook and intersecting State Route 76 (SR 76), before it crosses the county line into Riverside County and descends to the Inland Empire. In Riverside County, SR 79 runs concurrently with I-15 for a four-mile (6 km) portion in Temecula, before it splits away running north to Hemet. Then, intersects with the southern end of Interstate 215, which continues the designation of the Escondido Freeway. Interstate 15 continues north as the Temecula Valley Freeway.[6]

splits from its first and only spur route in California, Interstate 215, which runs through the two largest cities in the Inland Empire, San Bernardino and Riverside. runs along the eastern edge of the Santa Ana Mountains, passing the town of Lake Elsinore. It continues through the suburban areas in the western Inland Empire, passing Corona and Ontario, California. The highway is then rejoined by I-215, before heading northwards and upward through the Cajon Pass, an important mountain pass that is the primary route between Southern California and points eastwards and northeastwards.

Intersection of I-10 and I-15. that is located between its northern and southern junctions with is also used by many local residents as the major north south route for the western portions of the San Bernardino-Riverside-Ontario metropolitan area. serves a similar function in the eastern portion of the metropolitan area. These two highways are the only continuous north south freeways in the area.)

North of Limonite Avenue (south of SR 60), I-15 is known as the Ontario Freeway. intersects State Route 60, Interstate 10, and State Route 210 in rapid succession as it goes through Mira Loma, Ontario, and Rancho Cucamonga. As it nears Devore, merges with Interstate 215, where it is called the Barstow Freeway or the Mojave Freeway.

thereafter to Las Vegas, Salt Lake City, and on into Idaho and Montana, before ending at the Canadian border, where Alberta Highway 4 continues the ribbon of asphalt into Canada. Because it joins with the western end of I-70 in Southwestern Utah, also forms part of a major east west corridor connecting Southern California with Denver, St. Louis, and points east.

The Mojave Freeway is fairly busy on weekdays, since it connects the rapidly growing exurbs of the Victor Valley with the Los Angeles area. On weekends and holidays, however, it can sometimes be jammed with Californians driving to Las Vegas for short vacations.[7]

Construction is currently underway to rehabilitate the pavement on and to add truck lanes to separate autos from truck traffic.

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 and San Bernardino became I-215.

On January 24, 1957, the State Highway Commission defined the Escondido Freeway as what are now Routes 15 and 215 from Route 805 to Route 91. This entire segment was previously U.S. Route-395 when it was named. Since then, the definition was extended on Route 15 south to Route 8 by Assembly Concurrent Resolution 34, Chapter 67 in 1979.[8] Meanwhile, the segment of Route 15 from the San Diego County Line to the I-15/I-215 interchange was named the Temecula Valley Freeway in 1990.[9]

The original definition for the Corona Freeway, as named by the State Highway Commission on July 23, 1958, stated that it was "Routes 71, 91, and 15 from Route 10 West of Pomona to Route 215".[10]

This legal definition has been amended twice: First in 1990, the California Assembly passed Concurrent Resolution 125, Chapter 78, renaming I-15 between the San Diego County Line (which is further south from Interstate 215) and Bundy Canyon Road near Lake Elsinore as the Temecula Valley Freeway.[9]

Then in 1993, the California Assembly passed legislation officially designating State Route 71 as a part of the Chino Valley Freeway.[11] However, the name "Corona Freeway" is, confusingly, sometimes still applied to this portion of State Route 71; despite the change, guide signs on eastbound and SR 57 southbound at the Kellogg Interchange in Pomona still refer to SR 71 as the "Corona Freeway".

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 to pre-1964 Legislative Route 9 (now State Route 66, and was extended north to pre-1964 Legislative Route 31 (present I-15 and in 1935.[12] 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.[13] This was still the only existing piece in 1963, and had a planned freeway replacement to the east.[14]

In the 1964 renumbering, the route was assigned as State Route 31. It was added to the Interstate Highway System in February 1972 as a realignment of Interstate 15 (the former alignment became Interstate 15E).[15] Legislative changes were made in 1974, eliminating SR 31 (along with State Route 71 south of Corona) in favor of I-15.[16] 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.[17])

Future

California State Route 15 from Interstate 5 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 was completed by winter 2009.[18] Projects include adding truck lanes on hills ( at various locations), repaving of at various locations, adding exit numbers, renovating and rehabilitating the rest area between Baker and the Nevada State Line (Valley Wells Rest Area), reconstructing bridges in 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 Road and Yates Well Road.
