The '''Signature Bridge''' is a [[cantilever spar cable-stayed bridge]] which spans the [[Yamuna]] river at Shourya section, connecting [[Wazirabad, Delhi|Wazirabad]] to [[East Delhi]].<ref name=NDTV>{{cite news|url=https://www.ndtv.com/delhi-news/signature-bridge-to-be-ready-by-october-arvind-kejriwal-1518.37|title= Signature Bridge To Be Ready By October: Arvind Kejriwal|date= 6 July 2018| access-date=6 July 2018|publisher= www.ndtv.com}}</ref> It is India's first asymmetrical [[cable-stayed bridge]].<ref name=NDTV/> The [[Tower#Transportation support|pylon]] of the Signature bridge is the tallest structure in Delhi and is double the height of [[Qutb Minar|Qutub Minar]] with its 154-metre high viewing box, which is a location where visitors take [[selfie]]s.<ref>{{cite web|url=https://www.hindustantimes.com/delhi-news/154-metre-high-viewing-box-selfie-points-delhi-s-signature-bridge-opens-tomorrow/story-ss5rUlwFk5PI7Tkz2SV2AL.html|title=154-metre high viewing box, selfie points: Delhi’s Signature Bridge opens today}}</ref> It shortens the travel time between north and northeast Delhi.<ref>{{cite web|url=https://timesofindia.indiatimes.com/city/delhi/as-signature-bridge-opens-rush-to-ease-on-ring-road-and-nh-9/articleshow/66493331.cms|title=As Delhi's Signature Bridge opens, rush to ease on Ring Road and National Highway-9}}</ref>

==Background and History==
[[File:Wazirabad bridge on sahibi river.jpg|thumb|left|The old Wazirabad bridge|235x235px]]
In 1997, 28 school students died in an accident on the narrow [[Wazirabad, Delhi|Wazirabad]] bridge when their bus plunged into the river.<ref name=kolkata24x7>{{cite news|url=https://kolkata24x7.com/delhi-may-get-indias-first-asymmetrical-cable-stayed-bridge-by-october-will-decongest-wazirabad-bridge.html|title= নজির গড়ে দেশের বুকে তৈরি হচ্ছে প্রথম ‘অ্যাসমিট্রিক্যাল’ ব্রিজ|date= 6 July 2018| access-date=6 July 2018|publisher= kolkata24x7.com}}</ref> Since then, the Delhi government had plans to build another parallel wide bridge nearby to alleviate traffic congestion. By the end of 1998, the [[Government of Delhi|Delhi government]] finalised the draft plan for this bridge.<ref name= kolkata24x7/> 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 <ref>{{cite news|title= More funds for Signature Bridge may help it meet latest dead|url= https://timesofindia.indiatimes.com/city/delhi/more-funds-for-signature-bridge-may-help-it-meet-latest-deadline/articleshow/64890739.cms|date =7 July 2018| access-date= 7 July 2018 |publisher=Times of India }}</ref><ref name=theweekendleader>{{cite news|url=http://www.theweekendleader.com/Headlines/13516/delhi-government-clears-signature-bridge-project.html|title=Delhi government clears signature bridge project |date= 6 July 2018| access-date=7 July 2018|publisher=www.theweekendleader.com}}</ref> The [[Government of Delhi|Delhi government]] was financially restricted and it was very difficult for it to fund the extra rising budget.

A fresh deadline of end 2016 was set in 2013.<ref name=theweekendleader/> The bridge was finally inaugurated on 4 November 2018 by the then Chief Minister of Delhi [[Arvind Kejriwal]] after a number of delays.<ref name= Y/><ref name="NDTV_inaugration">{{cite news |title=Delhi's Signature Bridge To Have Selfie Spots, Glass Viewing Deck |url=https://www.ndtv.com/delhi-news/delhi-signature-bridge-opens-to-public-on-monday-heres-what-it-offers-1942195 |access-date=4 November 2018 |publisher=NDTV |date=3 November 2018}}</ref>

==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.<ref name="Dayaratnam2000">{{cite book|author1=T.K.
