Yangtze River Bridges And Tunnels
The bridges and tunnels across the Yangtze River carry rail and road traffic across China's longest and largest river and form a vital part of the country's transportation infrastructure. The river bisects China proper from west to east, and every major north–south bound highway and railway must cross the Yangtze. Large urban centers along the river such as Chongqing, Wuhan, and Nanjing also have 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 " Long River"), from Yibin to the river mouth in Shanghai, a distance of . Since then, over 75 bridges and six tunnels have been built over this stretch, the overwhelming majority since 1990. They reflect a broad array of bridge designs and, in many cases, represent significant achieve ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
List Of Largest Cable-stayed Bridges
This list ranks the world's cable-stayed bridges by the length of main span, i.e. the distance between the suspension towers. The length of the main span is the most common way to rank cable-stayed bridges. If one bridge has a longer span than another, it does not mean that the bridge is the longer from shore to shore, or from anchorage to anchorage. However, the size of the main span does often correlate with the height of the towers, and the engineering complexity involved in designing and constructing the bridge. Cable-stayed bridges with more than three spans are generally more complex, and bridges of this type generally represent a more notable engineering achievement, even where their spans are shorter. Cable-stayed bridges have the second-longest spans, after suspension bridges, of bridge types. They are practical for spans up to around . The Russky Bridge over the Eastern Bosphorus in Vladivostok, Russia, with its span, has the longest span of any cable-stayed bridge, di ...

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

Jinsha River
The Jinsha River (, Tibetan: Dri Chu, འབྲི་ཆུ) is the Chinese name for the upper stretches of the Yangtze River. It flows through the provinces of Qinghai, Sichuan, and Yunnan in western China. The river passes through Tiger Leaping Gorge. It is sometimes grouped together with the Lancang (upper Mekong) and Nu (upper Salween) as the ''Sanjiang'' ("Three Rivers") area, part of which makes up the Three Parallel Rivers of Yunnan Protected Areas.

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 eleventh tallest. This bridge spans a deep river gorge. The bridge's two towers, built on either rim of the gorge, a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
