In March 1926, the U.S. government auctioned off some lots on Key Biscayne that had been retained when the rest of the island was transferred to the State of Florida. The Mathesons wanted to have clear title to all of their land, and determined to outbid other interested parties for
875-602: A flat fee either when they enter or when they exit the toll road. In a variant of the closed toll system, mainline barriers are present at the two endpoints of the toll road, and each interchange has a ramp toll that is paid upon exit or entry. In this case, a motorist pays a flat fee at the ramp toll and another flat fee at the end of the toll road; no ticket is necessary. In addition, with most systems, motorists may pay tolls only with cash or change; debit and credit cards are not accepted. However, some toll roads may have travel plazas with ATMs so motorists can stop and withdraw cash for

Criticisms of toll roads include the time taken to stop and pay the toll, and the cost of the toll booth operators—up to about one-third of revenue in some cases. Automated toll-paying systems help minimise both of these. Others object to paying "twice" for the same road, namely in fuel taxes and in tolls. In addition to toll roads, toll bridges and toll tunnels are also used by public authorities to generate funds to repay

It is possible that the population in the Sargasso Sea migrated to the Atlantic as the Tethys closed at the end of the Miocene around 17 Ma. The origin of the Sargasso fauna and flora remained enigmatic for centuries. The fossils found in the Carpathians in the mid-20th century often called the "quasi-Sargasso assemblage", finally showed that this assemblage originated in

Although payments may still be made in cash, it is more common now to pay using an electronic toll collection system. In some places, payment is made using transponders which are affixed to the windscreen. Three systems of toll roads exist: open (with mainline barrier toll plazas ); closed (with entry/exit tolls); and open road (no toll booths, only electronic toll collection gantries at entrances and exits or at strategic locations on

Lower charges are levied on frequent 407 users who carry electronic transponders in their vehicles. The approach has not been without controversy: In 2003 the 407 ETR settled a class action with a refund to users. Throughout most of the East Coast of the United States, E-ZPass (operated under
9625-405: The highway. In some cases, the ticket displays the toll to be paid on exit. Upon exit, the driver must pay the amount listed for the given exit. Should the ticket be lost, a driver must typically pay the maximum amount possible for travel on that highway. Short toll roads with no intermediate entries or exits may have only one toll plaza at one end, with motorists travelling in either direction paying
9750-806: The hybrid systems they adopted during the late 20th century. These include the Massachusetts Turnpike , one of the oldest American toll roads, which went all-electronic in 2016, and the Pennsylvania Turnpike , America's oldest toll freeway, which went all-electronic in 2020, along with the Illinois Tollway , which both accelerated their transitions to such due to the COVID-19 pandemic . Turnpike trusts were established in England and Wales from about 1706 in response to
9875-898: The island. In November 1947 the Rickenbacker Causeway ;– 1.2 miles (1.9 km) of bridges and 2.7 miles (4.3 km) of roadway on fill – finally opened. In the late 1960s and 1970s the sites along the Rickenbacker Causeway continued to increase in popularity. After increasing in the mid 1960 because of the American television series Flipper , attendance to the Miami Seaquarium soared in 1968 when it started to display Hugo, its first killer whale (two years later, Lolita became their second. The two killer whales performed together until Hugo's death in 1980). Shortly afterward, Planet Ocean,
10000-399: The land. They ended up paying US$ 58,055 for a total of 6.84 acres (2.77 ha) of land, a record price per acre for the auction of U.S. government land up to that date. Then, on September 18, 1926, the 1926 Miami Hurricane crossed over Key Biscayne on its way to Miami. While there were no deaths on the island, most of the buildings on Key Biscayne were destroyed or badly damaged, and many of
10125-517: The latter 2,000 km (1,200 mi). Ocean currents such as the Gulf Stream transport eel larvae from the Sargasso Sea to foraging areas in North America, Europe, and northern Africa. Recent but disputed research suggests that eels possibly use Earth's magnetic field to navigate through the ocean both as larvae and as adults. The climate is influenced by the temperatures of the surface waters and water currents as well as winds. Because of
10250-666: The limits of the oceans and seas in 1953, but some of these definitions have been revised since then and some are not recognized by various authorities, institutions, and countries, for example the CIA World Factbook . Correspondingly, the extent and number of oceans and seas vary. The Atlantic Ocean is bounded on the west by North and South America. It connects to the Arctic Ocean through the Denmark Strait , Greenland Sea , Norwegian Sea and Barents Sea . To
10375-501: The lowest values are in the high latitudes and along coasts where large rivers enter. Maximum salinity values occur at about 25° north and south , in subtropical regions with low rainfall and high evaporation. The high surface salinity in the Atlantic, on which the Atlantic thermohaline circulation is dependent, is maintained by two processes: the Agulhas Leakage/Rings , which brings salty Indian Ocean waters into
10500-400: The mainline toll plazas (toll barriers). It is also possible for motorists to enter an 'open toll road' after one toll barrier and exit before the next one, thus travelling on the toll road toll-free. Most open toll roads have ramp tolls or partial access junctions to prevent this practice, known in the U.S. as " shunpiking ". With a closed toll system, vehicles collect a ticket when entering
10625-523: The maintenance and improvement of most of the main roads in England and Wales, which were used to distribute agricultural and industrial goods economically. The tolls were a source of revenue for road building and maintenance, paid for by road users and not from general taxation. The turnpike trusts were gradually abolished from the 1870s. Most trusts improved existing roads, but some new roads, usually only short stretches, were also built. Thomas Telford 's Holyhead road followed Watling Street from London but
10750-461: The manager of his device. In Italy, this occurs through the Autostrade per l'Italia interchange system. The Autostrada A36 , Autostrada A59 and Autostrada A60 are exclusively free-flow. On these motorways, those who do not have the electronic toll device on board must proceed with the payment by subsequently communicating the data to the motorway manager (by telephone, online or by going to
10875-514: The margins of the continents constitute about 11% of the bottom topography with few deep channels cut across the continental rise. The mean depth between 60°N and 60°S is 3,730 m (12,240 ft), or close to the average for the global ocean, with a modal depth between 4,000 and 5,000 m (13,000 and 16,000 ft). In the South Atlantic the Walvis Ridge and Rio Grande Rise form barriers to ocean currents. The Laurentian Abyss

Top large seas: The bathymetry of the Atlantic is dominated by a submarine mountain range called the Mid-Atlantic Ridge (MAR). It runs from 87°N or 300 km (190 mi) south of the North Pole to the subantarctic Bouvet Island at 54°S . Expeditions to explore the bathymertry of
11125-409: The median of the road). Some toll roads use a combination of the three systems. On an open toll system, all vehicles stop at various locations along the highway to pay a toll. (This is different from "open road tolling", where no vehicles stop to pay a toll.) While this may save money from the lack of need to construct toll booths at every exit, it can cause traffic congestion while traffic queues at
11250-732: The most extensive and voluminous large igneous provinces in Earth's history associated with the Triassic–Jurassic extinction event , one of Earth's major extinction events . Theoliitic dikes , sills , and lava flows from the CAMP eruption at 200 Ma have been found in West Africa, eastern North America, and northern South America. The extent of the volcanism has been estimated to 4.5 × 10 km (1.7 × 10 sq mi) of which 2.5 × 10 km (9.7 × 10 sq mi) covered what
11375-423: The motorways subject to toll payment must only proceed at a maximum speed of 30 kilometres per hour (20 mph) without the need to stop. The amount is directly proportional to the distance travelled by the vehicle, the coefficient of its class and a variable coefficient from motorway to motorway, called the kilometre rate. Unlike the closed motorway system, in the open system, the road user does not pay based on
11500-549: The need for better roads than the few and poorly-maintained tracks then available. Turnpike trusts were set up by individual Acts of Parliament , with powers to collect road tolls to repay loans for building, improving, and maintaining the principal roads in Britain . At their peak, in the 1830s, over 1,000 trusts administered around 30,000 miles (48,000 km) of turnpike road in England and Wales, taking tolls at almost 8,000 toll-gates. The trusts were ultimately responsible for
11625-409: The need for complete stops to pay tolls at these locations. By designing a toll gate specifically for electronic collection, it is possible to carry out open-road tolling, where the customer does not need to slow at all when passing through the toll gate. The U.S. state of Texas is using a system that has no toll booths. Drivers without a TollTag have their license plate photographed automatically and
11750-413: The newly incorporated Village of Key Biscayne . On the other hand, the entire length of the causeway, plus Crandon Boulevard, have become part of a popular bicycling route from Key Biscayne to Florida City. 25°44′01″N 80°09′45″W / 25.7335608°N 80.1623748°W / 25.7335608; -80.1623748 Toll road A toll road , also known as a turnpike or tollway ,
11875-571: The north to become the source for North Atlantic deep water, south of the Greenland-Scotland sill. These two intermediate waters have different salinity in the western and eastern basins. The wide range of salinities in the North Atlantic is caused by the asymmetry of the northern subtropical gyre and a large number of contributions from a wide range of sources: Labrador Sea, Norwegian-Greenland Sea, Mediterranean, and South Atlantic Intermediate Water. The North Atlantic deep water (NADW)
12000-699: The northeastern United States, the InterCounty Connector ( Maryland Route 200 ) was partially opened to traffic in February 2011, and the final segment was completed in November 2014. The first section of another all-electronic toll road, the Triangle Expressway , opened at the beginning of 2012 in North Carolina. Some toll roads are managed under such systems as the Build-Operate-Transfer (BOT) system. Private companies build
12125-425: The ocean's great capacity to store and release heat, maritime climates are more moderate and have less extreme seasonal variations than inland climates. Precipitation can be approximated from coastal weather data and air temperature from water temperatures. The oceans are the major source of atmospheric moisture that is obtained through evaporation. Climatic zones vary with latitude; the warmest zones stretch across
12250-399: The offices dedicated to payment). The closed motorway system is applied to most Italian motorways. It requires the driver of the vehicle to collect a special ticket at the entrance to the motorway and pay the amount due upon exit. If equipped with an electronic toll system the two procedures are completely automatic and the driver on the detection lanes located at the entrances and exits from
12375-507: The original interstate system funding. Houston's outer beltway of interconnected toll roads began in 1983, and many states followed over the last two decades of the 20th century adding new toll roads, including the tollway system around Orlando, Florida , Colorado's E-470 , and Georgia State Route 400 . London, in an effort to reduce traffic within the city, instituted the London congestion charge in 2003, effectively making all roads within
12500-565: The outlines of the coasts of the Old and the New Worlds. The remainder of the ridge was discovered in the 1920s by the German Meteor expedition using echo-sounding equipment. The exploration of the MAR in the 1950s led to the general acceptance of seafloor spreading and plate tectonics . Most of the MAR runs under water but where it reaches the surfaces it has produced volcanic islands. While nine of these have collectively been nominated
12625-464: The plantings were lost, including half of the coconut trees. D. P. Davis was not able to meet his end of the contract; he declared bankruptcy and then disappeared en route to Europe by ship. The Florida Land Boom was over, as were plans for a bridge. William Matheson died in 1930, leaving the island to his children. There was a flurry of interest in 1939, when the U.S. Navy approved a proposal to develop Virginia Key as an air base and sea port . There
12750-651: The pond" or "on the other side of the pond" or "across the pond", rather than to discuss the ocean itself. The term dates to 1640, first appearing in print in a pamphlet released during the reign of Charles I , and reproduced in 1869 in Nehemiah Wallington 's Historical Notices of Events Occurring Chiefly in The Reign of Charles I , where "great Pond" is used in reference to the Atlantic Ocean by Francis Windebank , Charles I's Secretary of State . The International Hydrographic Organization (IHO) defined
12875-411: The project. He got financier Ed Ball to buy $ 6 million worth of bonds financing the construction of the causeway. Land for the toll plaza and the causeway entrance was bought from the estate of James Deering . Fill dredged from the bottom of Biscayne Bay and dug from the mainland were used as both the road bed and public beach areas, both to the west of Virginia Beach and on the southern reaches of
13000-576: The registered owner will receive a monthly bill, at a higher rate than those vehicles with TollTags. A similar variation of automatic collection is the Toll Roads in Orange County, CA, US, wherein all entry or collection points are equipped with high-speed cameras which read license plates and users will have 7 calendar days to pay online using their plate number or else set up an account for automatic debits. The first all-electronic toll road in
13125-647: The roads and are given a limited franchise. Ownership is transferred to the government when the franchise expires. This type of arrangement is prevalent in Australia, Canada, Hong Kong, Indonesia, India, South Korea, Japan, and the Philippines . The BOT system is a fairly new concept that is becoming more popular in the United States, with California , Delaware , Florida , Illinois , Indiana , Mississippi , Texas , and Virginia already building and operating toll roads under this scheme. Pennsylvania , Massachusetts , New Jersey , and Tennessee are also considering
13250-528: The royal toll. Many modern European roads were originally constructed as toll roads in order to recoup the costs of construction and maintenance, and to generate revenue from passing travelers. In 14th-century England, some of the most heavily used roads were repaired with money raised from tolls by pavage grants. Widespread toll roads sometimes restricted traffic so much, by their high tolls, that they interfered with trade and cheap transportation needed to alleviate local famines or shortages. Tolls were used in
13375-438: The seafloor. The oldest oceanic crust in the Atlantic is up to 145 million years and is situated off the west coast of Africa and the east coast of North America, or on either side of the South Atlantic. In many places, the continental shelf and continental slope are covered in thick sedimentary layers. For instance, on the North American side of the ocean, large carbonate deposits formed in warm shallow waters such as Florida and
13500-700: The southbound continuation is Crandon Boulevard, which extends roughly five miles through the center of Key Biscayne, terminating near the Cape Florida Lighthouse in Bill Baggs Cape Florida State Park . Named after Eddie Rickenbacker , the American World War I flying ace and founder and president of Miami-based Eastern Air Lines , the causeway provides access to the Miami Seaquarium ,
13625-551: The subtropics to the northeastern Atlantic. There this water is cooled during winter and forms return currents that merge along the eastern continental slope of Greenland where they form an intense (40–50 Sv ) current which flows around the continental margins of the Labrador Sea . A third of this water becomes part of the deep portion of the North Atlantic Deep Water (NADW). The NADW, in turn, feeds
13750-421: The surface is usually covered with sea ice in the Labrador Sea , Denmark Strait , and Baltic Sea. The Coriolis effect circulates North Atlantic water in a clockwise direction, whereas South Atlantic water circulates counter-clockwise. The south tides in the Atlantic Ocean are semi-diurnal; that is, two high tides occur every 24 lunar hours. In latitudes above 40° North some east–west oscillation, known as
13875-648: The system. Some of these such as the Connecticut Turnpike and the Richmond–Petersburg Turnpike later removed their tolls when the initial bonds were paid off. Many states, however, have maintained the tolling of these roads as a consistent source of revenue. As the Interstate Highway System approached completion during the 1980s, states began constructing toll roads again to provide new freeways which were not part of
14000-545: The toll usually varies by vehicle type, weight, or number of axles , with freight trucks often charged higher rates than cars. Tolls are often collected at toll plazas, toll booths , toll houses , toll stations, toll bars, toll barriers, or toll gates. Some toll collection points are automatic, and the user deposits money in a machine which opens the gate once the correct toll has been paid. To cut costs and minimise time delay, many tolls are collected with electronic toll collection equipment which automatically communicates with
14125-668: The tolls. The toll is calculated by the distance travelled on the toll road or the specific exit chosen. In the United States, for instance, the Kansas Turnpike , Ohio Turnpike , New Jersey Turnpike , most of the Indiana Toll Road , New York State Thruway , and Florida's Turnpike currently implement closed systems. The Union Toll Plaza on the Garden State Parkway was the first ever to use an automated toll collection machine. A plaque commemorating
14250-428: The total volume of the Earth's oceans. Excluding its marginal seas, the Atlantic covers 81,760,000 km (31,570,000 sq mi) and has a volume of 305,811,900 km (73,368,200 cu mi). The North Atlantic covers 41,490,000 km (16,020,000 sq mi) (11.5%) and the South Atlantic 40,270,000 km (15,550,000 sq mi) (11.1%). The average depth is 3,646 m (11,962 ft) and
14375-482: The transport infrastructure which included many new or substantially improved roads, financed from tolls. The A5 road in Britain was built to provide a robust transport link between Britain and Ireland and had a toll house every few miles. In the 20th century, road tolls were introduced in Europe to finance the construction of motorway networks and specific transport infrastructure such as bridges and tunnels. Italy
14500-636: The upper layers of the circumpolar region, near the Drake Passage and the Falkland Islands. Both these currents receive some contribution from the Indian Ocean. On the African east coast, the small cyclonic Angola Gyre lies embedded in the large subtropical gyre. The southern subtropical gyre is partly masked by a wind-induced Ekman layer . The residence time of the gyre is 4.4–8.5 years. North Atlantic Deep Water flows southward below
14625-424: The western Atlantic and South Sandwich Trench (8,264 m or 27,113 ft) in the South Atlantic. There are numerous submarine canyons off northeastern North America, western Europe, and northwestern Africa. Some of these canyons extend along the continental rises and farther into the abyssal plains as deep-sea channels. In 1922, a historic moment in cartography and oceanography occurred. The USS Stewart used
14750-494: Was applied to the southern Atlantic as late as the mid-19th century. During the Age of Discovery , the Atlantic was also known to English cartographers as the Great Western Ocean . The pond is a term often used by British and American speakers in reference to the northern Atlantic Ocean, as a form of meiosis , or ironic understatement. It is used mostly when referring to events or circumstances "on this side of
14875-467: Was even talk of putting an air base on the north end of Key Biscayne, as well. In 1940 William Matheson's heirs donated 808.8 acres (327.3 ha) of land, including two miles (3.2 km) of beach on the Atlantic Ocean on the northern end of Key Biscayne to Dade County to be used as a public park (Crandon Park). The county commissioner who negotiated the gift, Charles H. Crandon, had offered for
15000-809: Was exceptional in creating a largely new route beyond Shrewsbury , and especially beyond Llangollen . Built in the early 19th century, with many toll booths along its length, most of it is now the A5 . In the modern day, one major toll road is the M6 Toll , relieving traffic congestion on the M6 in Birmingham. A few notable bridges and tunnels continue as toll roads including the Dartford Crossing and Mersey Gateway bridge. Some cities in Canada had toll roads in
15125-502: Was implemented on the WHSD. The system was designed for automatic calculation of the driving distance of a vehicle equipped with a transponder. The system does not require constructing toll plazas at each entrance to or exit from the highway. Transponders mounted on vehicles are read by signal receivers installed at the entrance and exit ramps. In Italy the only toll roads are the autostrade (Italian for motorways ). Major exceptions are
15250-416: Was introduced across Italy. Several US states now use mobile tolling platforms to facilitate use of payment via smartphones. Highway 407 in the province of Ontario , Canada, has no toll booths, and instead reads a transponder mounted on the windshields of each vehicle using the road (the rear licence plates of vehicles lacking a transponder are photographed when they enter and exit the highway). This made
15375-513: Was owned by William John “W.J.” Matheson , who had established a coconut plantation on the island. In February 1926 Matheson entered into an agreement with land developer D. P. Davis to develop and re-sell the northern half of Key Biscayne, including all of what is now Crandon Park and about half of the present Village of Key Biscayne. Later in 1926 the City of Coral Gables incorporated with Key Biscayne included in its boundaries. There were dreams of
15500-788: Was the Pennsylvania Turnpike in 1940. This was followed up by other toll roads, such as the Maine Turnpike in 1947, the Blue Star Turnpike in 1950, the New Jersey Turnpike in 1951, the Garden State Parkway in 1952, the West Virginia Turnpike and New York State Thruway in 1954, the Massachusetts Turnpike in 1957, and the Chicago Skyway and Indiana Toll Road in 1958. Other toll roads were also established around this time. With
15625-490: Was the first country in the world to build motorways reserved for fast traffic and for motor vehicles only. The Autostrada dei Laghi ("Lakes Motorway"), the first built in the world, connecting Milan to Lake Como and Lake Maggiore , and now parts of the Autostrada A8 and Autostrada A9 , was devised by Piero Puricelli and was inaugurated in 1924. Piero Puricelli, a civil engineer and entrepreneur, received
