The''' Mandovi bridge''' is a set of two bridges. It carries four lanes over the Mandovi river. It was Russian in design and the first to be used in this country. The first Mandovi bridge was built in 1971 and the second one in 1998.<ref>{{Cite book|url=https://www.researchgate.net/publication/306106258_Construction_of_Mandovi_bridge_III_final_report|title=Construction of Mandovi bridge III: final report|last=Mascarenhas|first=Antonio|date=31 July 2016}}</ref>

On 5 July 1986 the first bridge collapsed. After the collapse, this project required the dismantling of the old bridge structure and strengthening with by filling M20 concrete. The total cost of construction was {{INRConvert|20|m}}. The parallel bridges have a length of 600 metres each.

== History ==
Spanning across the Mandovi River near [[Panaji]] are three parallel Mandovi Bridges. The older bridge collapsed in the 1980s before a new bridge was constructed to accommodate heavy transport vehicles. The Mandovi Bridge links the towns of [[Panaji]] to [[Porvorim]]. On 14 June 2014, the foundation stone for the third bridge, which is the largest bridge in Goa, was laid by Prime Minister Narendra Modi. It will span {{convert|5|km|abbr=off}} and will be {{convert|15|m|abbr=off}} higher than the existing bridges and will be spaced in between the two. The 3rd Mandovi bridge is named Atal Setu after former Prime Minister of India Atal Bihari Vajpayee. The bridge was inaugurated on 27 January 2019 at the hands of Union Roads Minister Nitin Gadkari, Goa CM Manohar Parrikar.

=== Collapse in 1986 ===
On 5 July 1986, the first Mandovi bridge collapsed.<ref>{{Cite web|url=http://www.navhindtimes.in/thirty-years-after-mandovi-bridge-collapse/|title=Thirty years after Mandovi Bridge collapse|website=www.navhindtimes.in|language=en-US|accessdate=30 December 2017}}</ref> The main reason for failure was determined to be corrosion of the pre-stressed cable that attached the precast concrete segments to the piers.<ref>{{Cite web|url=http://in.viadeo.com/en/groups/detaildiscussion/?containerId=0021jfi4o52tbxm4&forumId=00233598sfq79e7&action=messageDetail&messageId=00228yxawb81mevz|title=MANDOVI RIVER BRIDGE COLLAPSE|website=Viadeo|language=en|accessdate=30 December 2017}}</ref> The debris of the bridge still remains in the river even after 30 years, it has seriously impacted the flow of the river.<ref>{{Cite news|url=https://www.heraldgoa.in/Goa/Goa/-Debris-of-1st-Mandovi-bridge-affecting-riverbed-water-flow/104823.html|title=Debris of 1st Mandovi bridge affecting riverbed, water flow|work=oHeraldo|accessdate=30 December 2017|language=en}}</ref>

== Mandovi River ==
[[File:Goa_Mandovi_Bridge_view_from_Ribandar.JPG|thumb|Mandovi Bridge from Ribandar]]
The '''Mahadayi/Mandovi River''' (''Mandovi'', pronounced {{IPA-kok|maːɳɖ(ɔ)wĩː|}}), also known as '''Mahadayi''' or '''Mhadei''' river, is described as the lifeline of the [[India]]n state of [[Goa]]. The Mandovi and the [[Zuari]] are the two primary rivers in the state of Goa. Mandovi joins with the Zuari at a common [[Creek (tidal)|creek]] at Cabo Aguada, forming the [[Mormugao]] harbour. [[Panaji]], the state capital and [[Old Goa]], the former capital of Goa, are both situated on the left bank of the Mandovi.

== The Third Mandovi Bridge ==
The '''[[Atal Setu (Goa)|Atal Setu]]''', also known as the '''Third Mandovi Bridge''' or '''Atal Bridge''', is a [[cable-stayed bridge]] in [[Goa]] that runs between [[Panaji]] and [[Porvorim]]. It carries the [[National Highway 66 (India)|NH 66]] over the tidal part of the [[Mandovi River]]. It has a total length of 5.1 kilometres (3.2&nbsp;mi). It is the third longest cable-stayed bridge in India. Two wheelers, three wheelers and [[bullock carts]] are strictly prohibited from using the Atal Setu  due to its height of 30 metres (98&nbsp;ft). It opened on 5 February 2019.<ref>Between July 2014 and April 2019 the replacement bridge (Atal Setu) was constructed parallel to the existing bridges.  At an estimated cost of $46,252,950 (355,00,00,000.00 rs), this project consisted of viaduct and cable stayed bridge with ramps near Merces Circle and Pundalik Nagar circle. The bridge was inaugurated 27 January 2019 with ongoing construction.</ref><ref>{{Cite web|url=https://www.gsidcltd.com/project/design-and-construction-of-bridge-across-river-mandovi-at-panaji-including-approaches-on-nh-17-between-pundalik-nagar-junction-porvorim-and-merces-junction/|title=Design-and-construction-of-bridge-across-river-mandovi-at-panaji-including-approaches-on-nh-17-between-pundalik-nagar-junction-porvorim-and-merces-junction|accessdate=16 April 2020|language=en}}</ref>
