Bosphorus Bridge
The Bosphorus Bridge (), known officially as the 15 July Martyrs Bridge () and colloquially as the First Bridge (), is the oldest and southernmost of the three suspension bridges spanning the Bosphorus strait (Turkish: ''Boğaziçi'') in Istanbul, Turkey, thus connecting Europe and Asia (alongside the Fatih Sultan Mehmet Bridge and Yavuz Sultan Selim Bridge). The bridge extends between Ortaköy (in Europe) and Beylerbeyi (in Asia). It is a gravity-anchored suspension bridge with steel towers and inclined hangers. The aerodynamic deck hangs on steel cables.

Minami Bisan-Seto Bridge
The is a series of double deck bridges connecting Okayama and Kagawa prefectures in Japan across a series of five small islands in the Seto Inland Sea. Built over the period 1978–1988, it is one of the three routes of the Honshū–Shikoku Bridge Project connecting Honshū and Shikoku islands and the only one to carry rail traffic. The total length is , and the longest span, the Minami Bisan-Seto Bridge, is . Crossing the bridge takes about 20 minutes by car or train. The ferry crossing before the bridge was built took about an hour. The bridges carry two lanes of highway traffic in each direction ( Seto-Chūō Expressway) on the upper deck and one railway track in each direction ( Seto-Ōhashi Line) on the lower deck. The lower deck was designed to accommodate an additional set of Shinkansen tracks for a proposed construction of the Shikoku Shinkansen line to Shikoku. History When in 1889 the first railway in Shikoku was completed between Marugame and Kotohira, a memb ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Humber Bridge
The Humber Bridge is a single-span road suspension bridge near Kingston upon Hull, East Riding of Yorkshire, England. When it opened to traffic on 24 June 1981, it was the longest of its type in the world; the Akashi Kaikyō Bridge surpassed it in 1998, and it became the thirteenth-longest by 2024. The bridge spans the Humber (an estuary formed by the rivers Trent and Ouse), between Barton-upon-Humber on the south bank and Hessle on the north bank, connecting the East Riding of Yorkshire with North Lincolnshire. Both sides of the bridge were in the non-metropolitan county of Humberside until its dissolution in 1996. The bridge can be seen for miles around, from as far as Patrington in the East Riding of Yorkshire, and from out to sea miles off the coast. It is a Grade I listed building. By 2006, the bridge carried an average of 120,000 vehicles per week. The toll was £3.00 each way for cars (higher for commercial vehicles), which made it the most expensive toll crossing ...

Mackinac Bridge
The Mackinac Bridge ( ; also referred to as the Mighty Mac or Big Mac) is a suspension bridge that connects the Upper Peninsula of Michigan, Upper and Lower Peninsula of Michigan, Lower peninsulas of the U.S. state of Michigan. It spans the Straits of Mackinac, a body of water connecting Lake Michigan and Lake Huron, two of the Great Lakes. Opened in 1957, the bridge is the world's List of longest suspension bridge spans, 27th-longest main span and is the longest suspension bridge between anchorages in the Western Hemisphere. The Mackinac Bridge is part of Interstate 75 in Michigan, Interstate 75 (I-75) and carries the Lake Michigan and Huron components of the Great Lakes Circle Tour across the straits; it is also a segment of the U.S. North Country Trail, North Country National Scenic Trail. The bridge connects the city of St. Ignace, Michigan, St. Ignace to the north with the village of Mackinaw City, Michigan, Mackinaw City to the south. Envisioned since the 1880s, the ...

Golden Gate Bridge
The Golden Gate Bridge is a suspension bridge spanning the Golden Gate, the strait connecting San Francisco Bay and the Pacific Ocean in California, United States. The structure links San Francisco—the northern tip of the San Francisco Peninsula—to Marin County, California, Marin County, carrying both U.S. Route 101 in California, U.S. Route 101 and California State Route 1 across the strait. It also carries pedestrian and bicycle traffic, and is designated as part of U.S. Bicycle Route 95. Recognized by the American Society of Civil Engineers as one of the Wonders of the World, Wonders of the Modern World, the bridge is one of the most internationally recognized symbols of San Francisco and California. The idea of a fixed link between San Francisco and Marin had gained increasing popularity during the late 19th century, but it was not until the early 20th century that such a link became feasible. Joseph Strauss (engineer), Joseph Strauss served as chief engineer for the p ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Verrazano-Narrows Bridge
The Verrazzano-Narrows Bridge ( ; also referred to as the Narrows Bridge, the Verrazzano Bridge, and simply the Verrazzano) is a suspension bridge connecting the boroughs of Staten Island and Brooklyn in New York City, United States. It spans the Narrows, a body of water linking the relatively enclosed New York Harbor with Lower New York Bay and the Atlantic Ocean. It is the only fixed crossing of the Narrows. The double-deck bridge carries 13 lanes of Interstate 278: seven on the upper level and six on the lower level. The span is named for Giovanni da Verrazzano, who in 1524 was the first European explorer to enter New York Harbor and the Hudson River. Engineer David B. Steinman proposed a bridge across the Narrows in the late 1920s, but plans were deferred over the next twenty years. A 1920s attempt to build a Staten Island Tunnel was aborted, as was a 1930s plan for vehicular tubes underneath the Narrows. Discussion of a tunnel resurfaced in the mid-1930s and ea ...

List Of Longest Suspension Bridge Spans
The world's longest suspension bridges are listed according to the length of their main span (i.e., the length of suspended roadway between the bridge's towers). The length of the main span is the most common method of comparing the sizes of suspension bridges, often correlating with the height of the towers and the engineering complexity involved in designing and constructing the bridge. If one bridge has a longer span than another, it does not necessarily mean that the bridge is longer from shore to shore (or from abutment to abutment). Suspension bridges have the longest spans of any type of bridge. Cable-stayed bridges, the next longest design, are practical for spans up to just over 1 kilometre (the longest cable-stayed bridge in the world has a 1,104m span). Therefore, as of January 2025, the 33 longest bridges on this list are the 33 longest spans of all types of vehicular bridges (other than floating pontoon bridges). The 1915 Çanakkale Bridge in Turkey holds the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Aerodynamic
Aerodynamics () is the study of the motion of atmosphere of Earth, air, particularly when affected by a solid object, such as an airplane wing. It involves topics covered in the field of fluid dynamics and its subfield of gas dynamics, and is an important domain of study in aeronautics. The term ''aerodynamics'' is often used synonymously with gas dynamics, the difference being that "gas dynamics" applies to the study of the motion of all gases, and is not limited to air. The formal study of aerodynamics began in the modern sense in the eighteenth century, although observations of fundamental concepts such as aerodynamic drag were recorded much earlier. Most of the early efforts in aerodynamics were directed toward achieving Aircraft#Heavier-than-air – aerodynes, heavier-than-air flight, which was first demonstrated by Otto Lilienthal in 1891. Since then, the use of aerodynamics through mathematical analysis, empirical approximations, wind tunnel experimentation, and computer si ...

Steel
Steel is an alloy of iron and carbon that demonstrates improved mechanical properties compared to the pure form of iron. Due to steel's high Young's modulus, elastic modulus, Yield (engineering), yield strength, Fracture, fracture strength and low raw material cost, steel is one of the most commonly manufactured materials in the world. Steel is used in structures (as concrete Rebar, reinforcing rods), in Bridge, bridges, infrastructure, Tool, tools, Ship, ships, Train, trains, Car, cars, Bicycle, bicycles, Machine, machines, Home appliance, electrical appliances, furniture, and Weapon, weapons. Iron is always the main element in steel, but other elements are used to produce various grades of steel demonstrating altered material, mechanical, and microstructural properties. Stainless steels, for example, typically contain 18% chromium and exhibit improved corrosion and Redox, oxidation resistance versus its carbon steel counterpart. Under atmospheric pressures, steels generally ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
