Deutz Suspension Bridge
The Deutz Suspension Bridge (german: Deutzer Hängebrücke) was a self-anchored suspension bridge using eyebar chains, located across the Rhine at Deutz in Cologne, Germany. It was built from 1913 to 1915. In 1935, it was named Hindenburg Bridge after Germany's second President died the previous year. It collapsed on 28 February 1945 during repair works and was replaced in 1948 by the world's first steel box girder bridge designed by Fritz Leonhardt and Gerd Lohmer. H. D. Robinson, who later worked with David B. Steinman on the Florianopolis Bridge, another eyebar chain bridge, consulted on the towers for the design of this Cologne bridge. It reportedly later served as inspiration for American bridge engineers and was specifically cited as a design influence on the Three Sisters bridges in Pittsburgh, Pennsylvania as well as for the Kiyosu Bridge on the Sumida River The is a river that flows through central Tokyo, Japan.

Three Sisters (Pittsburgh)
The Three Sisters are three similar self-anchored suspension bridges spanning the Allegheny River in downtown Pittsburgh, Pennsylvania at 6th, 7th, and 9th streets, generally running north/south. The bridges have been given formal names to honor important Pittsburgh residents: * Roberto Clemente (Roberto Clemente Bridge, Sixth Street Bridge) * Andy Warhol (Andy Warhol Bridge, Seventh Street Bridge) * Rachel Carson (Rachel Carson Bridge, Ninth Street Bridge) Designed by the Allegheny County, Pennsylvania, Allegheny County Department of Public Works, they were all built in a four-year period, from 1924 to 1928, by the American Bridge Company, replacing earlier bridges of various designs at the same sites. Their construction was mandated by the United States Department of War, War Department, citing navigable river clearance concerns. They are constructed of steel, and use steel eyebars in lieu of cables. The Three Sisters are historically significant because they are the only tri ...

Bridges Completed In 1915
A bridge is a structure built to span a physical obstacle (such as a body of water, valley, road, or rail) without blocking the way 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, and 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 still in existence and use. Etymology The ''Oxford English Dictionary'' traces the origin of the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Self-anchored Suspension Bridges
A self-anchored suspension bridge is a suspension bridge type in which the main cables attach to the ends of the deck, rather than directly to the ground or via large anchorages. The design is well-suited for construction atop elevated piers, or in areas of unstable soils where anchorages would be difficult to construct. Image:Bridge-suspension-anchorages.svg, Suspension bridge with the main cables attached to the ground (black squares) Image:Bridge-self-anchored.svg, Self-anchored suspension bridge; the main cables are attached to the end of the road deck The load path of the self-anchored suspension (SAS) bridge converts vertical loads into tension forces in the main cables which are countered by compressive forces in the towers and deck. The system balances forces internally without external anchorage requirements making it suitable for sites where large horizontal forces are difficult to anchor. This is similar to the method used in a tied-arch bridge where arch member com ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Cologne Haengebruecke 1925
Cologne ( ; german: Köln ; ksh, Kölle ) is the largest city of the German western state of North Rhine-Westphalia (NRW) and the fourth-most populous city of Germany with 1.1 million inhabitants in the city proper and 3.6 million people in the urban region. Centered on the left (west) bank of the Rhine, Cologne is about southeast of NRW's state capital Düsseldorf and northwest of Bonn, the former capital of West Germany. The city's medieval Catholic Cologne Cathedral (), the third-tallest church and tallest cathedral in the world, constructed to house the Shrine of the Three Kings, is a globally recognized landmark and one of the most visited sights and pilgrimage destinations in Europe. The cityscape is further shaped by the Twelve Romanesque churches of Cologne, and Cologne is famous for Eau de Cologne, that has been produced in the city since 1709, and "cologne" has since come to be a generic term. Cologne was founded and established in Germanic Ubii terri ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Sumida River
The is a river that flows through central Tokyo, Japan. It branches from the Arakawa River at Iwabuchi (in Kita-ku) and flows into Tokyo Bay. Its tributaries include the Kanda and Shakujii rivers. It passes through the Kita, Adachi, Arakawa, Sumida, Taito, Kōtō and Chūō wards of Tokyo. What is now known as the "Sumida River" was previously the path of the Ara-kawa. Toward the end of the Meiji era, the Ara-kawa was manually diverted to prevent flooding, as the Imperial Palace in Chiyoda is nearby. Art Sumida Gawa pottery was named after the Sumida River and was originally manufactured in the Asakusa district near Tokyo by potter Inoue Ryosai I and his son Inoue Ryosai II. In the late 1890s, Ryosai I developed a style of applied figures on a surface with flowing glaze, based on Chinese glazes called "flambe." Sumida pieces could be teapots, ash trays, or vases, and were made for export to the West. Inoue Ryosai III, grandson of Ryosai I, moved the manufacturing site ...

Florianopolis Bridge
The Hercílio Luz Bridge, located in Florianópolis, the capital city of Santa Catarina State in southern Brazil, is the first bridge constructed to link the Island of Santa Catarina to the mainland. It is the longest suspension bridge in Brazil. The central span was considered quite long (but not the longest, at 340 metres) at the time of its opening and is still one of the 100 largest suspension bridges. Construction commenced on 14 November 1922 with the bridge being inaugurated on May 13, 1926. The total length is 819.471 metres, with 259 metres of viaduct from the island, a central span of 339.471 metres and 221 metres of viaduct from the mainland. It was closed to the public on May 13, 1991 and reopened after complete restoration on December 30, 2019. Historical background The bridge was commissioned by Hercílio Luz, then governor of the state of Santa Catarina, to be the first permanent link between the island and the mainland.
