Burapha Withi Expressway
The Bang Na Expressway (full name: Bang Na - Bang Phli - Bang Pakong Expressway), officially Burapha Withi Expressway ( th, ทางพิเศษบูรพาวิถี), is a six-lane elevated highway in Thailand. It is a toll road and runs above National Highway route 34, (Bang Na–Trat Highway) owned by the Expressway Authority of Thailand The Expressway Authority of Thailand ( th, การทางพิเศษแห่งประเทศไทย) (EXAT) is a state enterprise under the Ministry of Transport. It was founded in 1972, and operates Thailand's expressway ( ''than ... (EXAT). The bridge was the achievement of Sukavich Rangsitpol deputy prime minister of Chuan Leekpai Cabinet (1992-1995). The Bang Na Expressway was designed by the late Louis Berger. History The Bang Na Expressway was conceived by the Expressway Authority of Thailand, Expressway and Rapid Transit Authority of Thailand (ETA). The structure was built using a design-build contracting m ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Elevated Highway
An elevated highway is a controlled-access highway that is raised above grade for its entire length. Elevation is usually constructed as viaducts, typically a long pier bridge. Technically, the entire highway is a single bridge. Reason to construct Elevated highways are more expensive to build than at-grade highways, and are usually only used where there is some combination of the following on the desired route: * difficulty controlling access at grade, for example where it would be very disruptive or expensive to eliminate existing crossings at grade * at grade construction would not allow for optimal traffic flow, for example due to hilly terrain or existing crossings * budget or time to eliminate impeding structures is high, due to acquisition costs, demolition costs, or environmental factors; for example: ** right of way through an urban area, where private property would have to be purchased or condemned, and might have to be litigated ** hills that are costly to level or ...

List Of Longest Bridges In The World
This is a list of the world's longest bridges that are more than in length sorted by their full length above land and water. The main span is the longest span without any ground support. '' Note: There is no standard way to measure the total length of a bridge. Some bridges are measured from the beginning of the entrance ramp to the end of the exit ramp. Some are measured from shoreline to shoreline. Yet others use the length of the total construction involved in building the bridge. Since there is no standard, no ranking of a bridge should be assumed because of its position in the list. Additionally, numbers are merely estimates and measures in U.S. customary units (feet) may be imprecise due to conversion rounding.''

Box Girder Bridges
A box girder bridge, or box section bridge, is a bridge in which the main beams comprise girders in the shape of a hollow box. The box girder normally comprises prestressed concrete, structural steel, or a composite of steel and reinforced concrete. The box is typically rectangular or trapezoidal in cross-section. Box girder bridges are commonly used for highway flyovers and for modern elevated structures of light rail transport. Although the box girder bridge is normally a form of beam bridge, box girders may also be used on cable-stayed and other bridges. Development of steel box girders In 1919, Major Gifford Martel was appointed head of the Experimental Bridging Establishment at Christchurch, Hampshire, which researched the possibilities of using tanks for battlefield engineering purposes such as bridge-laying and mine-clearing. Here he continued trials on modified Mark V tanks. The bridging component involved an assault bridge, designed by Major Charles Ingli ...

Transport In Bangkok
Bangkok has 9.7 million automobiles and motorbikes, a number the government says is eight times more than can be properly accommodated on existing roads. And those numbers are increasing by 700 additional cars and 400 motorbikes every day. Charoen Krung Road, the first road to be built by Western techniques, was completed in 1864. Since then, the road network has expanded to accommodate the sprawling city's needs. Besides roads, Bangkok is served by several other transport systems. Bangkok's canals and ferries historically served as a major mode of transport, but they have long since been eclipsed by land traffic. A complex elevated expressway network and Tollway helps bring traffic into and out of the city centre, but Bangkok's rapid growth has put a large strain on infrastructure. By the late-1970s, Bangkok became known as "the city of traffic disaster". Although rail transport was introduced in 1893 and electric trams served the city from 1894 to 1968, it was only in 1999 that ...

Controlled-access Highways In Thailand
Multiple toll-collecting controlled-access highway systems are operated in Thailand, currently serving the Greater Bangkok area and nearby provinces. The first expressway in Thailand is Chaloem Maha Nakhon Expressway, opened in 1981. Burapha Withi Expressway was the world's longest bridge from its opening in 2000 to 2010. Thailand's different controlled-access highway systems are: the expressways ( th, ทางพิเศษ, ) operated by the Expressway Authority of Thailand, the motorways (, ''thang luang phiset'') operated by the Department of Highways, and Don Muang Tollway Uttaraphimuk Elevated Tollway or colloquial name Don Muang Tollway, or just Tollway, Don Muang Tollway Public Company Limited (the Company) is the provider of tollway transport service for the section of Din Daeng District - Anusornsathan as a c ..., a concession highway owned by the Department of Highways and operated by Don Muang Tollway PCL.

Lake Pontchartrain Causeway
The Lake Pontchartrain Causeway (french: Chaussée du lac Pontchartrain), also known simply as The Causeway, is a fixed link composed of two parallel bridges crossing Lake Pontchartrain in southeastern Louisiana, United States. The longer of the two bridges is long. The southern terminus of the causeway is in Metairie, Louisiana, a south shore suburb of New Orleans. The northern terminus is in Mandeville, Louisiana, a north shore suburb of New Orleans. From 1969 until 2011, it was listed by ''Guinness World Records'' as the List of longest bridges in the world, longest bridge over water in the world; in 2011, in response to the opening of the longer Jiaozhou Bay Bridge in China, ''Guinness World Records'' created two categories for bridges over water: continuous and aggregate lengths over water. Lake Pontchartrain Causeway then became the longest bridge over water (continuous), while Jiaozhou Bay Bridge the longest bridge over water (aggregate). The bridges are supported by 9,5 ...

Limited-access Road
A limited-access road, known by various terms worldwide, including limited-access highway, dual-carriageway, expressway, limited access freeway, and partial controlled access highway, is a highway or arterial road for high-speed traffic which has many or most characteristics of a controlled-access highway (also known as a ''freeway'' or ''motorway''), including limited or no access to adjacent property, some degree of Dual carriageway, separation of opposing traffic flow, use of grade separated Interchange (road), interchanges to some extent, prohibition of slow modes of transport, such as bicycles, Working animal, (draught) horses, or self-propelled agricultural machines; and very few or no intersection (road), intersecting cross-streets or level crossings. The degree of isolation from local traffic allowed varies between countries and regions. The precise definition of these terms varies by jurisdiction.''Manual on Uniform Traffic Control Devices''Section 1A.13 Definitions of ...

Viaduct
A viaduct is a specific type of bridge that consists of a series of arches, piers or columns supporting a long elevated railway or road. Typically a viaduct connects two points of roughly equal elevation, allowing direct overpass across a wide valley, road, river, or other low-lying terrain features and obstacles. The term ''viaduct'' is derived from the Latin ''via'' meaning "road", and ''ducere'' meaning "to lead". It is a 19th-century derivation from an analogy with ancient Roman aqueducts. Like the Roman aqueducts, many early viaducts comprised a series of arches of roughly equal length. Over land The longest in antiquity may have been the Pont Serme which crossed wide marshes in southern France. At its longest point, it measured 2,679 meters with a width of 22 meters. Viaducts are commonly used in many cities that are railroad hubs, such as Chicago, Birmingham, London and Manchester. These viaducts cross the large railroad yards that are needed for freight trains there, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
