Kurushima Kaikyō Bridge
The , which connects the island of Ōshima to the main part of Shikoku, was the world's longest suspension bridge structure when completed, in 1999. The bridge is part of the Shimanami Kaidō, an expressway that spans a series of islands and connects Hiroshima Prefecture in Honshū to Ehime Prefecture in Shikoku, which is the smallest of Japan's four main islands. The bridge and the expressway were both conceived by the Honshū-Shikoku Bridge Project. Construction The Kurushima Kaikyō Bridge consists of three successive suspension bridges with six towers and four anchorages. There is a shared anchorage that joins each suspension bridge to the next. Its construction is similar to the western portion of San Francisco–Oakland Bay Bridge which is two successive suspension bridges with four towers and one shared anchorage. The bridge's total length of , is just a little longer than the total length of the two-tower Akashi Kaikyō Bridge, which is . * , main span , ranks 63rd ...

Seto Inland Sea
The , sometimes shortened to the Inland Sea, is the body of water separating Honshu, Shikoku, and Kyushu, three of the four main islands of Japan. It serves as a waterway connecting the Pacific Ocean to the Sea of Japan. It connects to Osaka Bay and provides a sea transport link to industrial centers in the Kansai region, including Osaka and Kobe. Before the construction of the San'yō Main Line, it was the main transportation link between Kansai and Kyūshū. Yamaguchi, Hiroshima, Okayama, Hyōgo, Osaka, Wakayama, Kagawa, Ehime, Tokushima, Fukuoka, and Ōita prefectures have coastlines on the Seto Inland Sea; the cities of Hiroshima, Iwakuni, Takamatsu, and Matsuyama are also located on it. The Setouchi region encompasses the sea and surrounding coastal areas. The region is known for its moderate climate, with a stable year-round temperature and relatively low rainfall levels. The sea experiences periodic red tides caused by dense groupings of certain phytoplankton th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Bridges Completed In 1999
A bridge is a structure built to Span (engineering), span a physical obstacle (such as a body of water, valley, road, or railway) without blocking the path underneath. It is constructed for the purpose of providing passage over the obstacle, which is usually something that is otherwise difficult or impossible to cross. There are many different designs of bridges, each serving a particular purpose and applicable to different situations. Designs of bridges vary depending on factors such as the function of the bridge, the nature of the terrain where the bridge is constructed and anchored, the material used to make it, and the funds available to build it. The earliest bridges were likely made with fallen trees and stepping stones. The Neolithic people built boardwalk bridges across marshland. The Arkadiko Bridge, dating from the 13th century BC, in the Peloponnese is one of the oldest arch bridges in existence and use. Etymology The ''Oxford English Dictionary'' traces the origin of ...

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] |
Great 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] |

San Francisco–Oakland Bay Bridge
The San Francisco–Oakland Bay Bridge, commonly referred to as the Bay Bridge, is a complex of bridges spanning San Francisco Bay in California. As part of Interstate 80 in California, Interstate 80 and the direct road between San Francisco and Oakland, California, Oakland, it carries about 260,000 vehicles a day on its two decks. It includes one of the List of longest suspension bridge spans, longest bridge 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 interurban, commuter trains on the lower, but after the Key System abandoned its rail service on April 20, 1958, the lower deck was conv ...
