What is a Viaduct? How is it different from a bridge

A viaduct is a series of bridges connected to each other to cross a valley or a low area or an area that is not completely covered by a body of water. A viaduct is a bridge, and not all bridges are viaducts, but all viaducts are bridges. Viaducts are mainly used in cities that are railway centers such as London, Manchester, Chicago and Atlanta to help create a way for freight trains and heavy traffic. With viaducts, city traffic is always kept to a minimum.

How is it different from a bridge?

A viaduct differs from a bridge in many ways because the bridge is a structure built exclusively to cross physical obstacles such as valleys, water or road. Viaducts are a form of bridges that are interconnected in a series of small multiple intervals. They can be used on the ground or above water bodies to facilitate crossover by people. When the viaducts are built on the ground, they are used in connection areas of the same height that cannot be crossed directly. Moreover, by land they are also used to create ways for trains and thus reduce congestion on the roads. Traffic avoidance is facilitated by viaducts with two or more bridges for the passage of vehicles and trains. When they are built on water,

Reasons for using the bridge viaduct

A viaduct is used mainly in highly industrialized countries and therefore finds it less expensive to build it than bridges. Furthermore, developing countries like India, China and Thailand are building viaducts to help reduce traffic congestion and save on land. This construction stimulates the need to use the viaduct on the bridge due to its greater importance.

Land use under viaducts

The viaducts guarantee the maximum use of the available land. Where they are built across the land, the space below can be used for other purposes such as shopping centers, clubs and parking lots. For example, in the United Kingdom most of the railway lines are built on viaducts that make infrastructure owners have large property. This property allows owners to invest under the arches of the viaducts, thus having an additional source of income.

Remarkable viaducts

The Millau Viaduct in southern France is a cable-stayed road bridge that crosses the Tarn river valley near Millau. The viaduct was designed by engineer Michael Virlogeux and an architect Norman Robert Foster. It is the highest vehicular bridge in the world with the top of a single pier at 1.125 feet, which is only slightly shorter than the 125ft Empire State Building and a little higher than the Eiffel tower. The viaduct was officially dedicated to December 12, 2004 and subsequently opened to traffic after two days. The Danyang-Kushan viaduct in China is a great bridge that made the Guinness World Records in 2011 the longest bridge in the world.

The Trend Of Demolishing Viaducts

The viaducts that were built several years ago in cities like Tokyo and Boston are currently demolished because they were considered ugly and seemed to divide the city. This separation prevents people from quickly accessing other parts of the city and is therefore demolished. Moreover, they do not seem to show modern technology and therefore be renewed to improve their appearance.
