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 1978–88, 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 extension of the Shinkansen to Shikoku. History When in 1889 the first railway in Shikoku was completed between Marugame and Kotohira, a member of the Prefectural ...

E30 Expressway (Japan)
E3 (short for Electronic Entertainment Expo or Electronic Entertainment Experience in 2021) is a trade event for the video game industry. The Entertainment Software Association (ESA) organizes and presents E3, which many developers, publishers, hardware, and accessory manufacturers use to introduce and advertise upcoming games and game-related merchandise to retailers and to members of the press. E3 includes an exhibition floor for developers, publishers, and manufacturers to showcase their titles and products for sale in the upcoming year. Before and during the event, publishers and hardware manufacturers usually hold press conferences to announce new games and products. Over time, E3 has been considered the largest gaming-expo of the year by importance and impact. Before 2017, E3 was an industry-only event; the ESA required individuals wishing to attend to verify a professional relationship with the video game industry. With the rise of streaming media, several of the press ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Akashi Kaikyō Bridge
The is a suspension bridge which links the city of Kobe on the Japanese island of Honshu to Iwaya on Awaji Island. It is part of the Kobe-Awaji-Naruto Expressway, and crosses the busy and turbulent Akashi Strait (''Akashi Kaikyō'' in Japanese). It was completed in 1998, and has the second longest central span of any suspension bridge in the world, at , only behind the 1915 Çanakkale Bridge that was opened in March 2022. It is one of the key links of the Honshū–Shikoku Bridge Project, which created three routes across the Inland Sea. History Background The Akashi Kaikyo Bridge forms part of the Kobe-Awaji-Naruto Expressway, the easternmost route of the bridge system linking the islands of Honshu and Shikoku. The bridge crosses the Akashi Strait (width 4 km) between Kobe on Honshu and Iwaya on Awaji Island; the other major part of the crossing is completed by the Ōnaruto Bridge, which links Awaji Island to Ōge Island across the Naruto Strait.

Truss Bridge
A truss bridge is a bridge whose load-bearing superstructure is composed of a truss, a structure of connected elements, usually forming triangular units. The connected elements (typically straight) may be stressed from tension, compression, or sometimes both in response to dynamic loads. The basic types of truss bridges shown in this article have simple designs which could be easily analyzed by 19th and early 20th-century engineers. A truss bridge is economical to construct because it uses materials efficiently. Design The nature of a truss allows the analysis of its structure using a few assumptions and the application of Newton's laws of motion according to the branch of physics known as statics. For purposes of analysis, trusses are assumed to be pin jointed where the straight components meet, meaning that taken alone, every joint on the structure is functionally considered to be a flexible joint as opposed to a rigid joint with strength to maintain its own shape, and ...

Cable-stayed Bridge
A cable-stayed bridge has one or more ''towers'' (or ''pylons''), from which cables support the bridge deck. A distinctive feature are the cables or stays, which run directly from the tower to the deck, normally forming a fan-like pattern or a series of parallel lines. This is in contrast to the modern suspension bridge, where the cables supporting the deck are suspended vertically from the main cable, anchored at both ends of the bridge and running between the towers. The cable-stayed bridge is optimal for spans longer than cantilever bridges and shorter than suspension bridges. This is the range within which cantilever bridges would rapidly grow heavier, and suspension bridge cabling would be more costly. Cable-stayed bridges were being designed and constructed by the late 16th century, and the form found wide use in the late 19th century. Early examples, including the Brooklyn Bridge, often combined features from both the cable-stayed and suspension designs. Cable-stay ...

List Of Largest Suspension Bridges
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 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. Therefore, , the 31 longest bridges on this list are the 31 longest spans of all types of vehicular bridges (other than floating pontoon bridges). Currently, the 1915 Çanakkale Bridge in Turkey holds the record since opening to traffic in March 2022, with a span of . Since 1998, the Ak ...

Suspension Bridge
A suspension bridge is a type of bridge in which the deck is hung below suspension cables on vertical suspenders. The first modern examples of this type of bridge were built in the early 1800s. Simple suspension bridges, which lack vertical suspenders, have a long history in many mountainous parts of the world. Besides the bridge type most commonly called suspension bridges, covered in this article, there are other types of suspension bridges. The type covered here has cables suspended between towers, with vertical ''suspender cables'' that transfer the live and dead loads of the deck below, upon which traffic crosses. This arrangement allows the deck to be level or to arc upward for additional clearance. Like other suspension bridge types, this type often is constructed without the use of falsework. The suspension cables must be anchored at each end of the bridge, since any load applied to the bridge is transformed into a tension in these main cables. The main cables conti ...

Viaduct
A viaduct is a specific type of bridge that consists of a series of arches, piers or columns supporting a long elevated railway or road. Typically a viaduct connects two points of roughly equal elevation, allowing direct overpass across a wide valley, road, river, or other low-lying terrain features and obstacles. The term ''viaduct'' is derived from the Latin ''via'' meaning "road", and ''ducere'' meaning "to lead". It is a 19th-century derivation from an analogy with ancient Roman aqueducts. Like the Roman aqueducts, many early viaducts comprised a series of arches of roughly equal length. Over land The longest in antiquity may have been the Pont Serme which crossed wide marshes in southern France. At its longest point, it measured 2,679 meters with a width of 22 meters. Viaducts are commonly used in many cities that are railroad hubs, such as Chicago, Birmingham, London and Manchester. These viaducts cross the large railroad yards that are needed for freight trains there, a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
San Francisco–Oakland Bay Bridge
The San Francisco–Oakland Bay Bridge, known locally as the Bay Bridge, is a complex of bridges spanning San Francisco Bay in California. As part of Interstate 80 and the direct road between San Francisco and Oakland, it carries about 260,000 vehicles a day on its two decks. It has one of the longest spans in the United States. The toll bridge was conceived as early as the California Gold Rush days, with "Emperor" Joshua Norton famously advocating for it, but construction did not begin until 1933. Designed by Charles H. Purcell, and built by American Bridge Company, it opened on Thursday, November 12, 1936, six months before the Golden Gate Bridge. It originally carried automobile traffic on its upper deck, with trucks, cars, buses and commuter trains on the lower, but after the Key System abandoned rail service on April 20, 1958, the lower deck was converted to all-road traffic as well. On October 12, 1963, traffic was reconfigured to one way traffic on each deck, westbound o ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
