Bãi Cháy Bridge
The Bãi Cháy Bridge ( vi, Cầu Bãi Cháy, links=no) is a cable-stayed bridge on Highway 18, connecting Hồng Gai with Bãi Cháy over the Cửa Lục straits, separating Cửa Lục Bay with Hạ Long Bay, on the territory of Hạ Long city, Quảng Ninh province, Vietnam. Bãi Cháy Bridge is the first, and at the time of its inauguration, the longest central-line cable-stayed bridge in Vietnam. Design The bridge has two outer span of reinforced pre-stressed concrete box beams, which are the widest of the world for this type of bridge. The towers are located on a huge pneumatic caisson foundation system, a modern construction technology first applied in Vietnam on this project. The bridge was constructed using a balanced cantilever technology, wherein the bridge beams reaching out over the water and the aligned ends connect at a head height of above the water level. This technique assured that vessels could still operate normally during the construction process. The br ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

It shares maritime borders with Thailand through the Gulf of Thailand, and the Philippines, Indonesia, and Malaysia through the South China Sea. Its capital is Hanoi and its largest city is Ho Chi Minh City (commonly known as Saigon). Vietnam was inhabited by the Paleolithic age, with states established in the first millennium BC on the Red River Delta in modern-day northern Vietnam. The Han dynasty annexed Northern and Central Vietnam under Chinese rule from 111 BC, until the first dynasty emerged in 939. Successive monarchical dynasties absorbed Chinese influences through Confucianism and Buddhism, and expanded ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Road Bridges In Vietnam
A road is a linear way for the conveyance of traffic that mostly has an improved surface for use by vehicles (motorized and non-motorized) and pedestrians. Unlike streets, the main function of roads is transportation. There are many types of roads, including parkways, avenues, controlled-access highways (freeways, motorways, and expressways), tollways, interstates, highways, thoroughfares, and local roads. The primary features of roads include lanes, sidewalks (pavement), roadways (carriageways), medians, shoulders, verges, bike paths (cycle paths), and shared-use paths. Definitions Historically many roads were simply recognizable routes without any formal construction or some maintenance. The Organization for Economic Co-operation and Development (OECD) defines a road as "a line of communication (travelled way) using a stabilized base other than rails or air strips open to public traffic, primarily for the use of road motor vehicles running on their own wheels", ...

Bridges Completed In 2006
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] |
Cable-stayed Bridges In Vietnam
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-staye ...

Transport In Vietnam
Transportation in Vietnam is improving rapidly in terms of both quantity and quality. Especially road traffic is growing rapidly but the major roads are dangerous and slow to travel on due to outdated design and an inappropriate traffic mix. In recent years, the construction of expressways has accelerated. Air travel is also important for long distance travel. Metro systems are under construction in the two metropolises of Vietnam, Hanoi and Ho Chi Minh City. Road transport The total length of the Vietnamese road system is about 222,179 km with 19.0% paved, mainly national roads and provincial roads (source: Vietnam Road Administration, 2004). The national road system length is 17,295 km with 27.6% of its length paved. The provincial road system is 27,762 km of length with 23.6% paved. The road network is relatively well developed, but in poor condition. Due to congestion and lack of safety, the average speed on the national roads is a mere . Road financing com ...

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 ...

Bãi Cháy
Bãi Cháy is a ward in Vietnam. It, along with the eastern part known colloquially as Hòn Gai, together make up the city of Hạ Long. Known as the city's "tourism zone", many hotels, beach resorts and other tourism hotspots are located within Bãi Cháy. The ward was linked to Hòn Gai via a ferry line until the inauguration of the Bãi Cháy Bridge in 2006. Etymology According to local legend, Bãi Cháy is the place where the Trần dynasty's forces, led by Trần Khánh Dư, burned the Mongols' vessels. A northeast wind then blew the fire toward the west side of the Cửa Lục Bay and inflamed the dry forest nearby. This story gives rise to the name "Bãi Cháy" (). Another local folk story tells that boats used to anchor at the west side of Cửa Lục. Fishermen gathered and burned Casuarinaceae's leaves around those vessels in order to deal with shipworm that bored into them. As people from Hồng Gai and elsewhere saw fire blazing up from this place regularly, they co ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
