Puzhehei Bridge
The Puzhehei Bridge is a cable-stayed bridge under construction in Yunnan, China. When completed the bridge will be the tallest in the world with the western tower having a structural height of . It will surpass the heigth of the current tallest bridge, the Millau Viaduct by . The bridge will carry the new Luqiuguangfu Expressway across the valley of the Nanpan River. The bridge will be among the ten longest cable-stayed bridges in the world with a main span of . It will also be one of the highest bridges in the world sitting above the original level of the Nanpan River. The full height won't be visible as the bridge will cross over the Yunpeng Dam reservoir so will sit above water level.

Nanpan River
The Nanpan River () has its source in the Yungui Plateau of eastern Yunnan Province. It then flows east, forming part of the border between Guizhou and Guangxi provinces. It joins with the Beipan River to become the Hongshui River The Hongshui River is a major river in the Guangxi Zhuang Autonomous Region in Southern China. It is one of the main rivers in the basin of the Xi River, which in its turn is one of the main tributaries of the Pearl River. Because it flows thr .... It is roughly long. Part of the Nanpan River is blocked by the Tianshengqiao Dam (), from which Wanfeng Lake () is formed. Along the Nanpan river, many ports were owned by the Cen clan who established in Guangxi to suppress a rebellion since 1053 AD.The Nanpan River: A Scenic Waterway in Southeast China, by Qin Nina.

China
China, officially the People's Republic of China (PRC), is a country in East Asia. It is the world's most populous country, with a population exceeding 1.4 billion, slightly ahead of India. China spans the equivalent of five time zones and borders fourteen countries by land, the most of any country in the world, tied with Russia. Covering an area of approximately , it is the world's third largest country by total land area. The country consists of 22 provinces, five autonomous regions, four municipalities, and two Special Administrative Regions (Hong Kong and Macau). The national capital is Beijing, and the most populous city and financial center is Shanghai. Modern Chinese trace their origins to a cradle of civilization in the fertile basin of the Yellow River in the North China Plain. The semi-legendary Xia dynasty in the 21st century BCE and the well-attested Shang and Zhou dynasties developed a bureaucratic political system to serve hereditary monarchies, or dyna ...

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-stayed ...

Steel
Steel is an alloy made up of iron with added carbon to improve its strength and fracture resistance compared to other forms of iron. Many other elements may be present or added. Stainless steels that are corrosion- and oxidation-resistant typically need an additional 11% chromium. Because of its high tensile strength and low cost, steel is used in buildings, infrastructure, tools, ships, trains, cars, machines, electrical appliances, weapons, and rockets. Iron is the base metal of steel. Depending on the temperature, it can take two crystalline forms (allotropic forms): body-centred cubic and face-centred cubic. The interaction of the allotropes of iron with the alloying elements, primarily carbon, gives steel and cast iron their range of unique properties. In pure iron, the crystal structure has relatively little resistance to the iron atoms slipping past one another, and so pure iron is quite ductile, or soft and easily formed. In steel, small amounts of carbon, other ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

List Of Tallest Bridges
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] |
Millau Viaduct
The Millau Viaduct (french: Viaduc de Millau, ) is a multispan cable-stayed bridge completed in 2004 across the gorge valley of the Tarn near (west of) Millau in the Aveyron department in the Occitanie Region, in Southern France. The design team was led by engineer Michel Virlogeux and English architect Norman Foster. it is the tallest bridge in the world, having a structural height of . The Millau Viaduct is part of the A75–A71 autoroute axis from Paris to Béziers and Montpellier. The cost of construction was approximately € 394 million ( $424 million). It was built over three years, formally inaugurated on 14 December 2004, and opened to traffic two days later on 16 December. The bridge has been consistently ranked as one of the greatest engineering achievements of modern times, and received the 2006 Outstanding Structure Award from the International Association for Bridge and Structural Engineering.

List Of Longest Cable-stayed Bridge Spans
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, disp ...

List Of Highest Bridges
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 deck (bridge), 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 are built across deep valleys or gorges. For example, (as of 8 February 2020) the Duge Bridge is the highest bridge in the world, but only the tenth tallest. This bridge spans a deep river gorge. The bridge's two towers, built on either rim of the gorge, are tall, but due to the depth of the river gorg ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
