The Supermarine S.6 is a 1920s British single-engined single-seat racing seaplane built by Supermarine. The S.6 continued the line of Supermarine seaplane racers that were designed for Schneider Trophy contests of the late 1920 and 1930s. Following the success of the Supermarine S.5 in the 1927 Schneider Trophy R. J. Mitchell designed a successor, the Supermarine S.6 to Specification 8/28. Refining the design of the earlier S.5, Mitchell now used all-metal construction. Although its lineage was evident, the new design had to accommodate a new powerplant; the 875 hp Napier Lion VIIB engine was judged to be incapable of further development, the S.6 was to use the new 1,900 hp Rolls-Royce R engine. With the problems of cooling attendant on such a high power output, the S.6 had surface radiators built into the floats as well as the wings, Mitchell arranged for airflow through the wing internal structure. Two aircraft were built at Woolston and operated by the RAF High Speed Flight, delivered in August 1929.
The two S. 6 racers were entered into the 1929 Schneider Trophy at England. N247 came first piloted by Flying Officer H. R. D. Waghorn at a speed of 328.63 mph. N248 was disqualified when it turned inside one of the marker poles, but nonetheless, set World closed-circuit records for 50 and 100 km during its run; the British government withdrew support for the next Schneider Trophy race in 1931 but due to a public outcry as well as private financing coming forward, funding was restored, a mere nine months before the contest. All that could be done was to modify the S.6 to take a more powerful 2,350 hp version of the Rolls-Royce R engine and two were built as the Supermarine S.6B. The two existing S.6s were re-designated as S.6As with new floats, added cooling areas and statically-balanced control surfaces. All four S.6s were brought up to a similar standard with nine Rolls-Royce R engines shared between them. Although the British team faced no competitors, the RAF High Speed Flight brought six Supermarine Schneider racers to Calshot Spit on Southampton Water for training and practice.
The aircraft were: S.5 N219, second at Venice in 1927, S.5 N220, winner at Venice in 1927, S.6A N247, that won at Calshot in 1929, S.6A N248, disqualified at Calshot in 1929, alongside the new and untested S.6Bs, S1595 and S1596. The British plan for the Schneider contest was to have S1595 fly the course alone and if its speed was not high enough, or it encountered mechanical failure the more proven S.6A N248 would fly the course. If both S1595 and N248 failed in their attempts, N247 held in reserve would be used; the S.6B S1596 was to attempt the World Air Speed Record. During training N247 flown by Navy Lt. G. N. Brinton was destroyed in a fatal takeoff accident, precluding any other plans with only the two S.6Bs and the surviving S.6A prepared for the final Schneider run. N248 did not fly in the race; until the 1960s, S.6A N248 was displayed incorrectly as S.6B S1596 as a visitor attraction in a building adjacent to Southampton Royal Pier. Now restored since 1983 and repainted in its original 1931 scheme, the S.6A is on display at the Solent Sky museum in Southampton, England.

Integrated Truss Structure
The Integrated Truss Structure of the International Space Station consists of a linear arranged sequence of connected trusses on which various unpressurized components are mounted such as logistics carriers, solar arrays, other equipment. It supplies the ISS with a bus architecture, it is 110 meters long and is made from aluminum and stainless steel. All truss components were named after their planned end-positions: Z for zenith, S for starboard and P for port, with the number indicating the sequential position; the S0 truss might be considered a misnomer, as it is mounted centrally on the zenith position of Destiny and is neither starboard nor port side. Most ISS truss segments were fabricated at the Marshall Space Flight Center and the Michoud Assembly Facility. NASA contractors such as Boeing were contracted to fabricate some elements; the trusses were transported or shipped to Kennedy Space Center's Space Station Processing Facility for final assembly and checkout. The structural framework were made using several manufacturing processes, including the investment casting, steel hot rolling, friction-stir and TIG welding processes.
The first truss piece, the Z1 truss, launched aboard STS-92 in October 2000. It contains the control moment gyroscope assemblies, electrical wiring, communications equipment, two plasma contactors designed to neutralize the static electrical charge of the space station. Another objective of the Z1 truss was to serve as a temporary mounting position for the "P6 truss and solar array" until its relocation to the end of the P5 truss during STS-120. Though not a part of the main truss, the Z1 truss was the first permanent lattice-work structure for the ISS much like a girder, setting the stage for the future addition of the station's major trusses or backbones. While the bulk of the Z1 truss is unpressurized, it features a Common Berthing Mechanism port that connects its nadir to the zenith port of Unity and contains a small pressurized dome that allowed astronauts to connect electrical ground straps between Unity and the truss without an EVA. In addition, the dome inside the CBM of Z1 can be used as storage space.
The Z1 truss features a forward-facing Manual Berthing Mechanism ring. This MBM is not a port and is not pressurized or electrically powered, but it can be operated with a handheld tool to berth any passive CBM to it; the Z1 truss's MBM was used only once, to temporarily hold PMA-2, while the Destiny lab was being berthed onto the Unity node during STS-98. Since the installation of the nearby S0 truss in April 2002, access to the MBM has been blocked. In October 2007, the P6 truss element was disconnected from Z1 and moved to P5; the Z1 truss is now used to house the CMGs, communications equipment and the plasma contactors. In December 2008, the Ad Astra Rocket Company announced an agreement with NASA to place a flight test version of its VASIMR ion thruster on the station to take over reboost duties. In 2013, Ad Astra announced specific plans to place the thruster module, named Aurora, on top of the Z1 truss in 2015. NASA and Ad Astra signed a contract for development of the VASIMR engine for up to three years in 2015.
This testing of the VX-200SSTM VASMIR engine for up to 100 hours and 100 kilowatts. However, in 2015 NASA ended plans for flying the VF-200 to the ISS. A NASA spokesperson stated that the ISS "was not an ideal demonstration platform for the desired performance level of the engines"; the S0 truss, forms the center backbone of the Space Station. It was attached on the top of the Destiny Laboratory Module during STS-110 in April 2002. S0 is used to route power to the pressurized station modules and conduct heat away from the modules to the S1 and P1 Trusses; the S0 truss is not docked to the ISS, but is connected with four Module to Truss Structure stainless steel struts. The P1 and S1 trusses are attached to the S0 truss, contain carts to transport the Canadarm2 and astronauts to worksites along the space station, they each flow 290 kg of anhydrous ammonia through three heat rejection radiators. The S1 truss was launched on STS-112 in October 2002 and the P1 truss was launched on STS-113 in November 2002.
Detailed design and construction of the S1 and P1 structures was conducted by McDonnell Douglas in Huntington Beach, CA. First parts were cut for the structure in 1996, delivery of the first truss occurred in 1999; the P2 and S2 trusses were planned as locations for rocket thrusters in the original design for Space Station Freedom. Since the Russian parts of the ISS provided that capability, the reboost capability of the Space Station Freedom design was no longer needed at that location. So P2 and S2 were canceled; the P3/P4 truss assembly was installed by the Space Shuttle Atlantis STS-115 mission, launched September 9, 2006, attached to the P1 segment. The P3 and P4 segments together contain a pair of solar arrays, a radiator and a rotary joint that will aim the solar arrays, connects P3 to P4. Upon its installation, no power was flowing across the rotary joint, so the electricity generated by the P4 solar array wings was only being used on the P4 segment, not the rest of the station. In December 2006 a major electrical rewiring of the station by STS-116 routed this power to the entire grid.
The S3/S4 truss asse
England is a country, part of the United Kingdom. It shares land borders with Wales to Scotland to the north-northwest; the Irish Sea lies west of England and the Celtic Sea lies to the southwest. England is separated from continental Europe by the North Sea to the east and the English Channel to the south; the country covers five-eighths of the island of Great Britain, which lies in the North Atlantic, includes over 100 smaller islands, such as the Isles of Scilly and the Isle of Wight. The area now called England was first inhabited by modern humans during the Upper Palaeolithic period, but takes its name from the Angles, a Germanic tribe deriving its name from the Anglia peninsula, who settled during the 5th and 6th centuries. England became a unified state in the 10th century, since the Age of Discovery, which began during the 15th century, has had a significant cultural and legal impact on the wider world; the English language, the Anglican Church, English law – the basis for the common law legal systems of many other countries around the world – developed in England, the country's parliamentary system of government has been adopted by other nations.
The Industrial Revolution began in 18th-century England, transforming its society into the world's first industrialised nation. England's terrain is chiefly low hills and plains in central and southern England. However, there is upland and mountainous terrain in the west; the capital is London, which has the largest metropolitan area in both the United Kingdom and the European Union. England's population of over 55 million comprises 84% of the population of the United Kingdom concentrated around London, the South East, conurbations in the Midlands, the North West, the North East, Yorkshire, which each developed as major industrial regions during the 19th century; the Kingdom of England – which after 1535 included Wales – ceased being a separate sovereign state on 1 May 1707, when the Acts of Union put into effect the terms agreed in the Treaty of Union the previous year, resulting in a political union with the Kingdom of Scotland to create the Kingdom of Great Britain. In 1801, Great Britain was united with the Kingdom of Ireland to become the United Kingdom of Great Britain and Ireland.
In 1922 the Irish Free State seceded from the United Kingdom, leading to the latter being renamed the United Kingdom of Great Britain and Northern Ireland. The name "England" is derived from the Old English name Englaland, which means "land of the Angles"; the Angles were one of the Germanic tribes that settled in Great Britain during the Early Middle Ages. The Angles came from the Anglia peninsula in the Bay of Kiel area of the Baltic Sea; the earliest recorded use of the term, as "Engla londe", is in the late-ninth-century translation into Old English of Bede's Ecclesiastical History of the English People. The term was used in a different sense to the modern one, meaning "the land inhabited by the English", it included English people in what is now south-east Scotland but was part of the English kingdom of Northumbria; the Anglo-Saxon Chronicle recorded that the Domesday Book of 1086 covered the whole of England, meaning the English kingdom, but a few years the Chronicle stated that King Malcolm III went "out of Scotlande into Lothian in Englaland", thus using it in the more ancient sense.
According to the Oxford English Dictionary, its modern spelling was first used in 1538. The earliest attested reference to the Angles occurs in the 1st-century work by Tacitus, Germania, in which the Latin word Anglii is used; the etymology of the tribal name itself is disputed by scholars. How and why a term derived from the name of a tribe, less significant than others, such as the Saxons, came to be used for the entire country and its people is not known, but it seems this is related to the custom of calling the Germanic people in Britain Angli Saxones or English Saxons to distinguish them from continental Saxons of Old Saxony between the Weser and Eider rivers in Northern Germany. In Scottish Gaelic, another language which developed on the island of Great Britain, the Saxon tribe gave their name to the word for England. An alternative name for England is Albion; the name Albion referred to the entire island of Great Britain. The nominally earliest record of the name appears in the Aristotelian Corpus the 4th-century BC De Mundo: "Beyond the Pillars of Hercules is the ocean that flows round the earth.
In it are two large islands called Britannia. But modern scholarly consensus ascribes De Mundo not to Aristotle but to Pseudo-Aristotle, i.e. it was written in the Graeco-Roman period or afterwards. The word Albion or insula Albionum has two possible origins, it either derives from a cognate of the Latin albus meaning white, a reference to the white cliffs of Dover or from the phrase the "island of the Albiones" in the now lost Massaliote Periplus, attested through Avienus' Ora Maritima to which the former served as a source. Albion is now applied to England in a more poetic capacity. Another romantic name for England is Loegria, related to the Welsh word for England and made popular by its use in Arthurian legend; the earliest known evidence of human presence in the area now known as England was that of Homo antecessor, dating to approximate
Rans S-6 Coyote II
The Rans S-6 Coyote II is an American single-engined, tractor configuration, two-seat, high-wing monoplane designed by Randy Schlitter and manufactured by Rans Inc. The Coyote is available as a completed light-sport aircraft; the original single seat S-4 Coyote was designed by Rans owner Randy Schlitter in 1982, as a result of his dissatisfaction with existing ultralight designs at the time. Construction of the first Coyote prototype was started in November 1982, with the first flight following in March 1983; the Coyote II two-seater was developed from the S-5 Coyote, itself a development of the S-4 Coyote. The initial two seat model, the S-6, was replaced by the improved S-6ES model in April 1990. In 1993, the ES was joined in production by the S-6S Super Coyote. All models of the S-6 feature a welded 4130 steel tube cockpit, with a bolted aluminum tube rear fuselage and tail surfaces all covered in fabric. In the initial S-6 and S-6ES, the fabric consists of pre-sewn Dacron envelopes, which shorten construction time.
The S-6S, uses the more traditional dope and fabric. The reported construction times for the ES are 250 man-hours versus 500 for the Super; the Coyote II kit can be ordered with tricycle or conventional landing gear, can be equipped with floats and skis. The original basic engine was the Rotax 503 of 50 hp, with the Rotax 582 of 64 hp being available as an option. Today, the standard engine is the 80 hp Rotax 912UL, with the 100 hp Rotax 912ULS being optional; the aircraft can be fitted with the Sauer S 2200 UL The Coyote has proven to be popular with customers, with over 1800 examples of the type having flown as of January 2008. In November 2010 615 were on the registers of European countries west of Russia, excluding Ireland. One example of the S-6ES was flown across the Atlantic Ocean twice. S-6 Initial version, standard engine 50 hp Rotax 503. No longer in production. S-6ES Improved version with "extended span" wings introduced in April 1990. Standard engine is the 100 hp Rotax 912ULS. Available with standard wing, "116" wing and "light sport wing".

Smartphones are a class of mobile phones and of multi-purpose mobile computing devices. They are distinguished from feature phones by their stronger hardware capabilities and extensive mobile operating systems, which facilitate wider software and multimedia functionality, alongside core phone functions such as voice calls and text messaging. Smartphones include various sensors that can be leveraged by their software, such as a magnetometer, proximity sensors, barometer and accelerometer, support wireless communications protocols such as Bluetooth, Wi-Fi, satellite navigation. Early smartphones were marketed towards the enterprise market, attempting to bridge the functionality of standalone personal digital assistant devices with support for cellular telephony, but were limited by their battery life, bulky form, the immaturity of wireless data services. In the 2000s, BlackBerry, Nokia's Symbian platform, Windows Mobile began to gain market traction, with models featuring QWERTY keyboards or resistive touchscreen input, emphasizing access to push email and wireless internet.
Since the unveiling of the iPhone in 2007, the majority of smartphones have featured thin, slate-like form factors, with large, capacitive screens with support for multi-touch gestures rather than physical keyboards, offer the ability for users to download or purchase additional applications from a centralized store, use cloud storage and synchronization, virtual assistants, as well as mobile payment services. Improved hardware and faster wireless communication have bolstered the growth of the smartphone industry. In the third quarter of 2012, one billion smartphones were in use worldwide. Global smartphone sales surpassed the sales figures for feature phones in early 2013; the first commercially available device that could be properly referred to as a "smartphone" began as a prototype called "Angler" developed by Frank Canova in 1992 while at IBM and demonstrated in November of that year at the COMDEX computer industry trade show. A refined version was marketed to consumers in 1994 by BellSouth under the name Simon Personal Communicator.
In addition to placing and receiving cellular calls, the touchscreen-equipped Simon could send and receive faxes and emails. It included an address book, appointment scheduler, world time clock, notepad, as well as other visionary mobile applications such as maps, stock reports and news; the term "smart phone" or "smartphone" was not coined until a year after the introduction of the Simon, appearing in print as early as 1995, describing AT&T's PhoneWriter Communicator. Beginning in the mid-late 1990s, many people who had mobile phones carried a separate dedicated PDA device, running early versions of operating systems such as Palm OS, Newton OS, Symbian or Windows CE/Pocket PC; these operating systems would evolve into early mobile operating systems. Most of the "smartphones" in this era were hybrid devices that combined these existing familiar PDA OSes with basic phone hardware; the results were devices that were bulkier than either dedicated mobile phones or PDAs, but allowed a limited amount of cellular Internet access.
The trend at the time, that manufacturers competed on in both mobile phones and PDAs was to make devices smaller and slimmer. The bulk of these smartphones combined with their high cost and expensive data plans, plus other drawbacks such as expansion limitations and decreased battery life compared to separate standalone devices limited their popularity to "early adopters" and business users who needed portable connectivity. In March 1996, Hewlett-Packard released the OmniGo 700LX, a modified HP 200LX palmtop PC with a Nokia 2110 mobile phone piggybacked onto it and ROM-based software to support it, it had a 640×200 resolution CGA compatible four-shade gray-scale LCD screen and could be used to place and receive calls, to create and receive text messages and faxes. It was 100% DOS 5.0 compatible, allowing it to run thousands of existing software titles, including early versions of Windows. In August 1996, Nokia released the Nokia 9000 Communicator, a digital cellular PDA based on the Nokia 2110 with an integrated system based on the PEN/GEOS 3.0 operating system from Geoworks.
The two components were attached by a hinge in what became known as a clamshell design, with the display above and a physical QWERTY keyboard below. The PDA provided e-mail; when closed, the device could be used as a digital cellular telephone. In June 1999 Qualcomm released the "pdQ Smartphone", a CDMA digital PCS smartphone with an integrated Palm PDA and Internet connectivity. Subsequent landmark devices included: The Ericsson R380 by Ericsson Mobile Communications; the first device marketed as a "smartphone", it was the first Symbian-based phone, with PDA functionality and limited Web browsing on a resistive touchscreen utilizing a stylus. Users could not install their own software on the device, however; the Kyocera 6035, a dual-nature device with a separate Palm OS PDA operating system and CDMA mobile phone firmware. It supported limited Web browsing with the PDA software treating the phone hardware as an attached modem. Handspring's Treo 180, the first smartphone that integrated the Palm OS on a GSM mobile phone having telephony, SMS messaging and Internet access built in to the OS.
The 180 model had a thumb-type keyboard and the 180g version had a Graffiti handwriting recognition area, instead. In 1999, Japanese wireless provider NTT DoCoMo launched i-mode, a new
Samsung Galaxy S6
The Samsung Galaxy S6, Samsung Galaxy S6 Edge, Samsung Galaxy S6 Edge+ are Android smartphones manufactured and marketed by Samsung Electronics. The S6 line serves as a successor to the Galaxy S5; the S6 and S6 Edge smartphones were unveiled in the first "Samsung Unpacked 2015" event at the Mobile World Congress on March 1, 2015, while the bigger S6 Edge+ was unveiled together with the Samsung Galaxy Note 5 in the second "Samsung Unpacked 2015" event at New York on August 13, 2015. Alongside the S6, Samsung unveiled the S6 Edge, a variant whose screen is wrapped along the sides of the device; the Galaxy S6 and S6 Edge were first released on April 10, 2015 while the S6 Edge+ was released on August 21, 2015. Although the overall design of the Galaxy S6 still features some similarities to prior models, the construction of the device itself was revamped, with a metal unibody frame and glass backing instead of plastic; the devices introduced an improved camera, a streamlined user interface, support for major wireless charging standards and support for a mobile payments platform that allows the device to emulate the magnetic strip from a credit card.
The S6 features other hardware improvements as well, including a 1,440 x 2,560 pixels display, a new in-house system-on-chip that utilizes a 14 nm FinFET manufacturing process, an improved fingerprint scanner. The Galaxy S6, S6 Edge and S6 Edge+ received positive reviews from critics, who praised the devices' upgraded build quality over prior models, along with improvements to their displays, performance and other changes. However, Samsung's decision to remove the ability to expand their storage or remove the battery was panned as being alienating to power users, the S6 Edge was panned for not making enough use of its curved display to justify its increased cost over the standard Samsung Galaxy S6 which resulted in the release of the bigger S6 Edge+ on. Rumors surrounding the Galaxy S5's successor began to surface in January 2015, it was reported that Samsung would be using an in-house Exynos system-on-chip rather than the Qualcomm Snapdragon 810 on the S6 due to concerns surrounding overheating.
That month, Qualcomm affirmed in an earnings report that its products would not be included in " large customer's flagship device". Fellow competitor LG Electronics disputed the allegations surrounding the 810. In early-February 2015, Bloomberg News reported that the S6 was to have a metal body, was to be produced in a normal version, a version with a screen curved along the left and right sides of the device to the Galaxy Note Edge; the S6's design was teased in a promotional webpage released by T-Mobile US on 22 February 2015, which showed a curved body and carried the tagline "Six Appeal". Samsung unveiled the Galaxy S6 and S6 Edge during the first Samsung Unpacked 2015 event at Mobile World Congress on 1 March 2015, for a release on 10 April 2015 in 20 countries. In Japan, the S6 and S6 Edge are marketed under the Galaxy brand, with most references to Samsung removed; the Galaxy S6 models are designed to address criticisms and feedback received from prior models, target the majority of users.
As part of these goals, a number of features and capabilities seen on the Galaxy S5 were removed, such as its waterproofing and USB 3.0 port. The S6's new design approach is the culmination of a shift in practices that began with 2014's Galaxy Alpha, the first Galaxy smartphone to feature metal as part of its construction. A new reflective coating was designed in-house to give the devices' backings a "jewel-like" appearance; the device's software was simplified. Additionally, the Galaxy S6's battery is no longer user-replaceable; the Galaxy S6 line retains similarities in design to previous models, but now uses a unibody frame made of aluminium alloy 6013 with a glass backing, a curved bezel with chamfered sides to improve grip, the speaker grille was moved to the bottom. The devices are available in "White Pearl", "Black Sapphire", "Gold Platinum" color finishes; the S6 carries some regressions in its design over the S5. Both use non-removable batteries; the Galaxy S6 line supports both the Power Matters Alliance wireless charging standards.
The Galaxy S6 line is powered by a 64-bit Exynos 7 Octa 7420 system-on-chip, consisting of four 2.1 GHz Cortex-A57 cores, four 1.5 GHz Cortex-A53 cores, 3 GB of LPDDR4 RAM for the S6 and S6 Edge while 4 GB of LPDDR4 for the S6 Edge+. The processor is Samsung's first to use a 14 nm FinFET manufacturing process, whic
California County Routes in zone S
There are 34 routes assigned to the "S" zone of the California Route Marker Program, which designates county routes in California. The "S" zone includes county highways in Imperial, Riverside, San Diego, Santa Barbara counties. County Route S1 known as Sunrise Highway for a portion of its length, is a 34.08 mi long county route located in San Diego County, California. It begins at SR 94 near Barrett and moves northward across Interstate 8, just west of the Laguna Summit; this segment is known as Buckman Springs Road. North of I-8, it is a National Forest Scenic Byway; the route begins at SR 94 near Barrett not far from the Mexican border. From there, it heads northward along Buckman Springs Road. Soon afterwards, it enters the Cleveland National Forest; when the road reaches Interstate 8, while Buckman Springs Road continues northeastward across the freeway, CR S1 continues in a northwest direction along Old Highway 80, the original alignment of U. S. Route 80 in California, it closely parallels I-8 for several miles.
Upon crossing the freeway at Laguna Junction, CR S1 separates from Old Highway 80 and becomes Sunrise Scenic Byway. From Interstate 8, it begins its ascent into the Laguna Mountains; the route here was built along a cliff overlooking Pine Valley to its west. Around here, the vegetation still consists of sagebrush; as the route gains elevation through Cleveland National Forest, the route becomes more forested. Around here, numerous campgrounds dot the side of the road. There is a picnic area overlooking Anza-Borrego Desert State Park near the Burnt Rancheria Campground, said to contrast the forest scenery along the route. Upon passing the settlement of Laguna Mountain, the vegetation along the route consists of dead trees devastated by the 2003 Cedar Fire; as the route approaches its north end at SR 79, Lake Cuyamaca is visible. The north terminus is located just north of Cuyamaca Rancho State Park where it meets State Route 79; the route was established by the county in the year 1959, where the entire route was designated as it is now.
No major numbering or routing changes occurred throughout its history. The northern segment of the route was established as a Scenic Byway in 1959. County Route S2 is a county highway in the US state of California, it runs for 65 miles, north -- south, in San Diego County. S2 is the third longest county route in California and is exclusively a two-lane rural road, it follows the route of the former Southern Emigrant Trail and Butterfield Overland Mail. The highway begins at a junction with State Route 98 in Ocotillo and runs north through an interchange with Interstate 8; this part is called Imperial Highway. The highway crosses into its name changes to Sweeney Pass Road. Farther north, the name of the highway changes to the Great Southern Overland Stage Route of 1849 at a remote junction; the highway crosses State Route 78 at Scissors Crossing in a desert community now called Shelter Valley, its name changes to San Felipe Road. The highway ends at a junction with State Route 79 near the community of Warner Springs.
Images from County Route S2 The route was defined in 1970. County Route S3 begins at a junction with State Route 78 and runs north over Yaqui Pass to Borrego Springs, bearing the name Yaqui Pass Road, it left again onto Borrego Springs Road. It ends at a junction with County Route S22 called Christmas Circle, its total length is 12.1 miles. There is one call box on this highway, it is at Yaqui Pass summit. The highway is part of the Juan Bautista de Anza National Historic Trail Auto Tour Route. County Route S4 is a road in the northern city limits of San Diego; the route traverses across Interstate 15 as Poway Road east to State Route 67. The route's western terminus is at I-15, where the road continues west as Rancho Penasquitos Boulevard, traverses across SR 56, ends as Carmel Mountain Road. Eastward, the road traverses through the city of Poway with the name Poway Road and has its east end at SR 67. Within Poway, it is one of the busiest streets in the city; the route was established in 1959. County Route S5 is a road in both Poway and San Diego, California.
Its south end is County Route S4, or Poway Road, its north end is Interstate 15. The road's south end is at County Route S4 in Poway, it winds north through Poway as Espola Road and turns west, ending at Interstate 15 as Rancho Bernardo Road. The route was established in 1959. County Route S6 is a county route in California, it connects Del Mar with Palomar Mountain across San Diego County. It is one of few San Diego County Routes with a discontinuity in its routing. S6 starts at San Diego County Route S21 in Del Mar as Via de la Valle, it crosses Interstate 5 and meets with S8 in Rancho Santa Fe at the intersection of Via de la Valle and Paseo Delicias. At El Camino Del Norte the name changes to Del Dios Highway, past the community of Del Dios and into Escondido, California. In Escondido, S6 runs along West and East Valley Parkways, to Valley Center Road through Valley Center, California. S6 ends at State Route 76. About four miles east on SR 76, S6 begins again as South Grade Road, which winds northward on Palomar Mountain.
It intersects with S7 continues north until it ends at the Palomar Observatory. The route was defined in 1959. County Route S7 is a county route in San Diego County, California that provides access to Palomar Mountain. S7's western terminus is at State Route 76 east of California, it begins as a dirt road known as the Nate H
