Yangtze River Bridges And Tunnels
The bridges and tunnels across the Yangtze River carry rail and road traffic across China's longest and largest List of rivers of China, river and form a vital part of the Transport in China, country's transportation infrastructure. The river bisects China proper from west to east, and every major north–south bound China National Highways, highway and List of railway lines in China, railway must cross the Yangtze. Large urban centers along the river such as Chongqing, Wuhan, and Nanjing also have Urban rail transit in China, urban mass transit rail lines crossing the Yangtze. Pontoon bridges have been used by militaries for two thousand years on the Yangtze, but until the completion of the Wuhan Yangtze River Bridge in 1957, there were no permanent bridges along the main stretch of the river known as ''Chang Jiang'' (the "Yangtze River#Names, Long River"), from Yibin to the river mouth in Shanghai, a distance of . Since then, over 75 bridges and six tunnels have been built ov ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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] |

Simple Suspension Bridge
A simple suspension bridge (also rope bridge, swing bridge (in New Zealand), suspended bridge, hanging bridge and catenary bridge) is a primitive type of bridge in which the deck of the bridge lies on two parallel load-bearing cables that are anchored at either end. They have no towers or piers. The cables follow a shallow downward catenary arc which moves in response to dynamic loads on the bridge deck. The arc of the deck and its large movement under load make such bridges unsuitable for vehicular traffic. Simple suspension bridges are restricted in their use to foot traffic. For safety, they are built with stout handrail cables, supported on short piers at each end, and running parallel to the load-bearing cables. Sometime these may be the primary load-bearing element, with the deck suspended below. Simple suspension bridges are considered the most efficient and sustainable design in rural regions, especially for river crossings that lie in non-floodplain topography such a ...

Tongtian River
The Tongtian River ( zh, , ) or Zhi Qu ( Tibetan) is a long river in Qinghai Province in western China. It begins at the confluence of the Ulan Moron and Dangqu rivers, before flowing southeast and meeting the Jinsha River near the border of Qinghai and Sichuan. It is part of the Yangtze River drainage basin. Name The Chinese name comes from a fabled river in the classic novel ''Journey to the West''. In antiquity, it was called the Yak River. In Mongolian, this section is known as the Murui-ussu (, lit. "Winding Water") and is sometimes confused with the nearby Baishui. Yule, Henry.

List Of Tallest Bridges In The World
This list of tallest bridges includes bridges with a structural height of at least . The of a bridge is the maximum vertical distance from the uppermost part of a bridge, such as the top of a bridge tower, to the lowermost exposed part of the bridge, where its piers, towers, or mast pylons emerge from the surface of the ground or water. Structural height is different from , which measures the maximum vertical distance between the bridge deck (the road bed of a bridge) and the ground or water surface beneath the bridge span. A separate list of highest bridges ranks bridges by deck height. Structural height and deck height The difference between tall and high bridges can be explained in part because some of the highest bridges are built across deep valleys or gorges. For example, (as of 1 July 2020) the Duge Bridge is the highest bridge in the world, but only the fifteenth tallest. This bridge spans a deep river gorge. The bridge's two towers, built on either rim of the gorge, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
List Of Highest Bridges In The World
This list of highest bridges includes bridges with a deck height of at least . The of a bridge is the maximum vertical drop distance between the bridge deck (the road, rail or other transport bed of a bridge) and the ground or water surface beneath the bridge span. Deck height is different from , which is a measure of the maximum vertical distance from the uppermost part of a bridge, such as the top of a bridge tower to the lowermost exposed part of the bridge, where its piers emerge from the surface of the ground or water. Structural height and deck height The difference between tall and high bridges can be explained in part because some of the highest bridges span the deepest part of their valley or gorge supported from above, with their ground supports built on relatively high terrain only; some of the tallest bridges have support structures on the lowest part of the valley floor. For example, (as of 24 March 2025) the Duge Bridge is the highest bridge in the world, but ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Girder Bridge
A girder bridge is a bridge that uses girders as the means of supporting its deck. The two most common types of modern steel girder bridges are plate and box. The term "girder" is often used interchangeably with "beam" in reference to bridge design. However, some authors define beam bridges slightly differently from girder bridges. A girder may be made of concrete or steel. Many shorter bridges, especially in rural areas where they may be exposed to water overtopping and corrosion, utilize concrete box girder. The term "girder" is typically used to refer to a steel beam. In a beam or girder bridge, the beams themselves are the primary support for the deck, and are responsible for transferring the load down to the foundation. Material type, shape, and weight all affect how much weight a beam can hold. Due to the properties of the second moment of area, the height of a girder is the most significant factor to affect its load capacity. Longer spans, more traffic, or wider spacin ...
