It runs between U.S. Route 101 near Santa Margarita and Interstate 15 in Barstow . It has junctions with Interstate 5 near Buttonwillow , State Route 99 in Bakersfield , State Route 202 in Tehachapi , State Route 14 near Mojave , and U.S. Route 395 at Kramer Junction. SR 58 also provides access to Edwards Air Force Base . At various points it

166-533: A congestion pricing system based on the real-time levels of traffic. All tolls are collected using an open road tolling system, and therefore there are no toll booths to receive cash. For the segment in Riverside County, carpools with three or more people are not charged, provided they have a FasTrak Flex transponder with its switch set to indicate the number of the vehicle's occupants (1, 2, or 3 or more). Solo drivers and carpools with two people may also use

249-665: A decade later. Between 2004 and 2008, construction extended the lanes north from SR 56 to Del Lago Boulevard in Escondido. Then, between 2009 and 2012, work was done to widen the southern reversible segment from two lanes to four, and then extend the corridor north to SR 78. The lanes, dubbed a "highway within a highway", include a movable "zipper" barrier for 16 miles (26 km), which can be changed to create an extra lane as demand allows. In addition, five direct access ramps allow for easier local access, as well as access to bus service from MTS Rapid . The second segment of HOT lanes

332-440: A few miles north of San Luis Obispo , SR 58 heads east along the former US 101 (El Camino Real) for one mile. SR 58 then heads east and up the winding mountain road, passing through a thinly populated area and an intersection with SR 229 . Alternatives such as SR 46 to the north or SR 166 to the south are recommended, as much of this section of SR 58 is prohibited to truck traffic. However, this section of SR 58 does pass through

415-407: A freeway. Except where prefixed with a letter, postmiles were measured on the road as it was in 1964 , based on the alignment that existed at the time, and do not necessarily reflect current mileage. R reflects a realignment in the route since then, M indicates a second realignment, L refers to an overlap due to a correction or change, and T indicates postmiles classified as temporary ( for

However, as soon as the reroute was made, the cities of San Bernardino and Riverside voiced concerns that this new routing, which completely bypassed their city centers, would have a negative effect on their development plans. Together, these cities devised

5727-399: The same place that its continuation, SR 15 , begins its southward journey. I-15 goes through Mission Valley and Kearny Mesa , intersecting with SR 52 just before merging with SR 163 . After traversing the Marine Corps Air Station Miramar , I-15 comes into Rancho Peñasquitos , where it meets the eastern end of SR 56 . Northward, the route crosses Lake Hodges inside

5810-435: The segment of Legislative Route 58 between US 101 near Santa Margarita and State Route 33 at McKittrick was not signed prior to 1964. Note that US 466 was co-signed with US 99 , now State Route 99, between Bakersfield and Famoso Junction . Between Famoso and US 101 at Paso Robles, US 466 largely became SR 46. The eastern terminus was originally at I-15 in northeastern Barstow. SR 58 was rerouted to I-15 in Barstow south of

5893-426: The signs were replaced some time later. Present SR 15 was signed after the creation of I-15 in 1968. Since I-15's southern terminus was at I-8, SR 15 was signed mostly along 40th Street and Wabash Boulevard in San Diego to its merge with I-5 . The portion between Adams Avenue and I-805 remained a city street for a long time, and this portion was not completed until January 2000. For this reason,

5976-631: The state highways managed by ANAS generally follows the SS n scheme, where n is a number ranging from 1 ( Aurelia ) up to 700 (of the Royal Palace of Caserta ) depending on the date of establishment of the state highway. Newly built ANAS roads, not yet classified, are identified by the acronym NSA, an acronym for nuova strada ANAS ("new ANAS road"). State highways can be technically defined as main extra-urban roads (type B road) or as secondary extra-urban roads (type C road). State highways that cross towns with

6059-525: The steep downward grade. The southbound lanes provide a runaway truck ramp as a safety feature. The two halves of the highway rejoin shortly before reaching Cajon Summit. North of the Cajon Pass, I-15 traverses the High Desert cities of Hesperia , where it meets the southern end of US 395 , and Victorville . I-15 passes through desert for 25 miles (40 km) before reaching Barstow , where it meets

6142-798: The switchable FasTrak Flex tags directly, and instead instructs those drivers who do qualify for free to just remove their FasTrak standard tag off their windshield or cover it in the provided mylar bag to avoid being charged. A separate project in San Bernardino County would extend the express lanes to Duncan Canyon Road in Fontana, and there are also long-range plans to extend the toll lanes at least as far south as SR 74 (Central Avenue) in Lake Elsinore. I-15 replaced US 395 between San Diego and Temecula, US 66 between San Bernardino and Barstow, and US 91 north of Barstow. I-15

6225-462: The system is completely unsigned, aside from the Trans-Canada routes. This makes Canada unique in that national highway designations are generally secondary to subnational routes. In Germany , state roads ( Landesstraßen or Staatsstraßen ) are a road class which is ranking below the federal road network ( Bundesstraßen ). The responsibility for road planning, construction and maintenance

6308-657: The upper San Diego city limits. I-15 continues north into Escondido , where it intersects with SR 78 . North of Escondido, I-15 goes through hilly terrain and farmland, passes under the Lilac Road Bridge and approaches the community of Fallbrook near the SR ;76 interchange. It passes the community of Rainbow , crosses the Riverside county line and descends into the Inland Empire . In Temecula , I-15 runs concurrently with SR 79 for 3.2 miles (5 km) before

6391-518: The word "state" in this sense means "government" or "public" (as in state housing and state schools ), not a division of a country. New Zealand's state highway system is a nationwide network of roads covering the North Island and the South Island . As of 2006, just under 100 roads have a "State Highway" designation. The NZ Transport Agency administers them. The speed limit for most state highways

6474-564: The word "state" is used in its sense of a sovereign state or country. By this meaning a state highway is a road maintained and numbered by the national government rather than local authorities. Australia 's important urban and inter-regional routes not covered by the National Highway or National Route systems are marked under the State Route system. They can be recognised by blue shield markers. They were practically adopted in all states by

6557-474: Was "Routes 71, 91, and 15 from Route 10 West of Pomona to Route 215". 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 I-215 ) and Bundy Canyon Road near Lake Elsinore as the Temecula Valley Freeway. Then, in 1993,

6640-468: Was extended north to pre-1964 Legislative Route 31 (present I-15 and I-215) in 1935. The piece south of US 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 replacement to the east. In the 1964 renumbering ,

6723-512: Was finished. (A 1986 map shows state maintenance continuing north past SR 60 to Jurupa Street, where it turned east to I-15. ) The segment signed as California SR 15 from I-5 to I-8 in San Diego is planned to be redesignated as part of I-15 once this segment is completely upgraded to Interstate standards , namely where the freeway's interchange with SR 94 is concerned. The interchange currently has left-exits and blind merges, and

6806-400: Was initially planned to run from I-10 near 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 (299.72 km) within the state. California successfully argued in favor of the addition south to San Diego, suggesting that the freeway would connect the major military bases, the former March AFB (now March ARB ) and

6889-541: Was its former routing as a city street. It continues seamlessly into the southern terminus of I-15 at I-8; on the northbound conversion to I-15 at I-8, there is no "End SR 15" sign. There are various local names for the highway, such as the Escondido Freeway between San Diego and Escondido. I-15 between SR 163 and Pomerado Road / Miramar Road is known as the Semper Fi Highway in recognition of
