Signature Bridge

The Signature Bridge is a cantilever spar cable-stayed bridge which spans the Yamuna river at Shourya section, connecting Wazirabad to East Delhi. [2] It is India's first asymmetrical cable-stayed bridge. [2] The pylon of the Signature bridge is the tallest structure in Delhi and is double the height of Qutub Minar with its 154-metre high viewing box, which acts as selfie points for visitors. [3] It shortens the travel time between north and northeast Delhi. [4]

Background and History

The old wazirabad bridge

In 1997, 28 school students died in an accident on the narrow Wazirabad bridge when their bus plunged into the river. [5] Since then, the Delhi government had plans to build another parallel wide bridge nearby to alleviate traffic congestion. By the end of 1998, the Delhi government finalised the draft plan for this bridge. [5] However, construction of the bridge was delayed due to multiple reasons, mainly lack of manpower and financial difficulties. When the project started, its final cost was Rs. 1518.37 crore [6] [7] The Delhi government was financially restricted and it was very difficult for it to fund the extra rising budget. Work finally started in 2010. A fresh deadline of end 2016 was set in 2013. [7] The bridge was finally inaugurated on 4 November 2018 by the then Chief Minister of Delhi Arvind Kejriwal after a number of delays. [8] [9]

Details

The bridge is a Cantilever spar cable-stayed bridge, a type of Cable-stayed bridge in which cables are in a combination of radial and semi-harp arrangement; cables are spaced apart on the pylon, like the harp design, but connected to one point or a number of closely spaced points on the deck. [10] The dynamically shaped pylon consists of 2 inclined columns, which are rigidly connected to the driving lanes and bend mid-way. [8] The upper portion of the pylon anchors the back-stay cables as well as the main-span cables and the self-weight of the pylon balances out the self-weight of the superstructure through the eccentric location of its center of gravity with respect to the pivot point of the pylon footing, reducing the load on back-stay cables which are fewer in number converged from the main-span cables. [8] The bridge is 675 meters long and 35.2 meters wide. [8] Built on the Yamuna river, this bridge connects east Delhi to Wazirabad. Tourists can be transported to the top of the main pillar, which is 154 m high, from where distant views of North Delhi can be seen. [11]

<span class="mw-page-title-main">Cable-stayed bridge</span> Type of bridge with cables directly from towers

A cable-stayed bridge has one or more towers, 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.

<span class="mw-page-title-main">Cantilever spar cable-stayed bridge</span>

A cantilever spar cable-stayed bridge is a modern variation of the cable-stayed bridge. This design has been pioneered by the structural engineer Santiago Calatrava in 1992 with the Puente del Alamillo in Seville, Spain. In two of his designs the force distribution does not depend solely upon the cantilever action of the spar (pylon); the angle of the spar away from the bridge and the weight distribution in the spar serve to reduce the overturning forces applied to the footing of the spar. In contrast, in his swinging Puente de la Mujer design (2002), the spar reaches toward the cable supported deck and is counterbalanced by a structural tail. In the Assut de l'Or Bridge (2008), the curved backward pylon is back-stayed to concrete counterweights.

<span class="mw-page-title-main">Extradosed bridge</span>

An extradosed bridge employs a structure that combines the main elements of both a prestressed box girder bridge and a cable-stayed bridge. The name comes from the word extrados, the exterior or upper curve of an arch, and refers to how the "stay cables" on an extradosed bridge are not considered as such in the design, but are instead treated as external prestressing tendons deviating upward from the deck. In this concept, they remain part of the main bridge superstructure.
