Revision as of 20:52, 15 June 2008
Template:Infobox Interstate/Intrastate 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 has a length of Template:Mi to km in the state. It is a major thoroughfare for traffic between Southern California and Las Vegas. It is also the main route for traffic between San Diego and the Inland Empire.
This route is part of the California Freeway and Expressway System[1] and is eligible for the State Scenic Highway System[2].
Route description
Major cities Bolded cities are officially designated control cities for signs[3] |
---|
I-15's southern terminus is I-8 in San Diego. From I-8, it runs north through Escondido in San Diego County, passing MCAS Miramar. The highway passes through hilly terrain and avocado farmland before entering Riverside County near the rapidly-growing community of Temecula.
In Murieta, I-15 splits from its first (and only) spur route in California, I-215, which runs through the two largest cities in the Inland Empire: San Bernardino and Riverside. I-15 runs along the eastern edge of the Santa Ana Mountains, passing the community of Lake Elsinore. The freeway continues through the suburban areas in the western Inland Empire, passing Corona and Ontario. The highway is then rejoined by I-215 before it then heads northward and upward through Cajon Pass, a historic pass which serves as the primary route between Southern California and the Mojave Desert region (as well as Las Vegas).
The portion of I-15 which is located between the northern and southern junctions with I-215 is also used by local residents as the major north-south route for the western portions of the San Bernardino-Riverside-Ontario metropolitan area. (I-215 serves a similar function in the eastern portion of the metropolitan area; the two are the only continuous north-south freeways in the area.)
North of the Cajon Pass, I-15 traverses the Mojave Desert cities of Hesperia and Victorville. The freeway passes through mostly unspoiled desert for Template:Mi to km before reaching Barstow, the last city I-15 passes through in California. The only other settlement I-15 passes through in its final Template:Mi to km is Baker, known as the "Gateway to Death Valley" and is home to the world's largest thermometer. 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.[citation needed] I-15 leaves California near the gambling town Primm, Nevada (formerly known as Stateline, Nevada).
Escondido Freeway
Heading northward, I-15 begins at Interstate 8 at the same place that its continuation, State Route 15, begins its southward journey. I-15 goes through Mission Valley and intersects with State Route 52 and merges with State Route 163. After traversing the MCAS Miramar base, I-15 emerges into Carmel Valley, where it intersects with the end of State Route 56. I-15 continues north into Escondido, where it interchanges with State Route 78. North of Escondido, I-15 goes through rural areas, intersecting State Route 76 before it crosses the county line into Riverside County. In Riverside County, SR 79 runs concurrently with I-15 for a four-mile portion within the city of Temecula, California before it splits away to continue north to Hemet. Then, I-15 intersects with the southern end of Interstate 215, which carries the designation of the Escondido Freeway. Interstate 15 continues north as the Temecula Valley Freeway.[4]
On January 24, 1957, the State Highway Commission defined the Escondido Freeway as what is now Routes 15 and 215 from Route 805 to Route 91. Note that this entire segment was previously 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.[5] 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.[6]
I-15 between SR 163 and Miramar Road is known as the Semper Fi Highway in recognition of the nearby MCAS Miramar.[7]
There are high-occupancy toll lanes in the center of I-15 from State Route 163 to State Route 56.[8] Construction is currently ongoing (as of spring 2008) to extend these lanes northward, possibly as far as SR 78.
Temecula Valley Freeway
The Temecula Valley Freeway is a segment of Interstate 15 in Riverside County, California, United States, traveling southeast to northwest through the southern portions of the Inland Empire region. It begins at the Riverside/San Diego county line, where the Corona Freeway ends; travels north through the cities of Murrieta (where the Escondido Freeway designation switches to Interstate 215) and Temecula; and ends at Bundy Canyon Road near Lake Elsinore. Thereafter, I-15 is designated as the Corona Freeway.
Corona Freeway
The Corona Freeway is a freeway traveling through Riverside County, California. It is signed as Interstate 15 along its entire length. The Corona Freeway runs north-south from its southern terminus at I-215 near Temecula to its northern terminus at the Riverside Freeway (State Route 91).
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".[9]
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.[10]
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 SR 71; despite the change, guide signs on I-10 eastbound and SR 57 southbound at the Kellogg Interchange in Pomona still refer to SR 71 as the "Corona Freeway".
Ontario Freeway
The Ontario Freeway is a segment of Interstate 15 in southern California, running through San Bernardino and Riverside counties. It is the principal north-south freeway through the fast-growing Inland Empire region, in the far eastern suburbs of Los Angeles.
North of Limonite Avenue (south of SR 60), I-15 is known as the Ontario Freeway. I-15 intersects State Route 60, Interstate 10, and State Route 210 in rapid succession as it goes through Norco and Rancho Cucamonga. As it nears Devore, I-15 merges with Interstate 215 and becomes what is known as the Barstow Freeway or the Mojave Freeway.
Mojave Freeway
The Mojave Freeway is the name given to the segment of Interstate 15 in California between the northern I-215 junction and the Nevada state line. The portion between former State Route 30 and the Nevada state line is also known as the Barstow Freeway. It is the principal route between Los Angeles and Las Vegas.
The Ontario (I-15) and Escondido (I-215) freeways meet in Devore, a foothill town just northwest of San Bernardino, merging into the Mojave Freeway. Crossing the San Bernardino Mountains at the Cajon Pass, the freeway enters the Victor Valley and continues northeast through the Mojave Desert. It terminates at the Nevada state line; I-15 continues thereafter to Las Vegas, Salt Lake City, and the cities of western Montana before ending at the U.S.-Canada border.
The Mojave Freeway is fairly busy on weekdays, as it connects the rapidly growing exurbs of the Victor Valley with the Los Angeles area. On weekends and holidays, however, it can be completely jammed with Southern Californians driving to Las Vegas for short vacations.
History
This section needs expansion. You can help by adding to it. (January 2008) |
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 186.24 miles 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.
Future
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. [1] Projects include adding truck lanes on hills (39 miles at various locations), repaving 76 miles of I-15 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.
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 lanes which already exist between SR 56 and SR 163. It appears that this extension will move the northern terminus of the HOT lanes to a location at or near the interchange with SR 78.
Exit list
- Note: Except where prefixed with a letter, postmiles were measured in 1964, based on the alignment as it existed at that time, and do not necessarily reflect current mileage. The numbers reset at county lines; the start and end postmiles in each county are given in the county column.
