'''Diffo Bridge''' is a pre-stressed [[Box girder bridge|concrete box girder bridge]] over the Diffo river (Chipu river)<ref>{{Cite web|url=https://arunachalobserver.org/2019/01/19/sitharaman-dedicates-strategic-bridge-diffo-bridge-boon-troop-movement-indo-china-border/|title=Sitharaman dedicates strategic bridge {{!}} 'Diffo Bridge a boon for troop movement to Indo-China border'|date=2019-01-19|website=Arunachal Observer|language=en-US|access-date=2019-09-11}}</ref> in [[Arunachal Pradesh]], [[India]]. This {{convert|426.60|m|ft}} long bridge was inaugurated in 2019 by the Union Defense Minister [[Nirmala Sitharaman]].<ref name="PIB"/><ref name="GKT">{{Cite web|url=https://currentaffairs.gktoday.in/diffo-bridge-arunachal-pradesh-inaugurated-01201964718.html|title=Diffo Bridge of Arunachal Pradesh Inaugurated|date=2019-01-19|website=Current Affairs Today|language=en-US|access-date=2019-09-11}}</ref>

==Construction==
The construction started in 2011<ref name="GKT" /> by [[Border Roads Organisation]] under [[Project Udayak]].<ref name="GKT" /> It was built for an estimated cost of {{INRConvert|4847.83|l|lk=b}}, which was funded by the [[Ministry of Road Transport and Highways|Union Ministry of Road Transport and Highways]].<ref name="PIB" /> Tough working conditions in an inhospitable terrain facing turbulent [[flash flood]]s, made construction difficult. It was completed in 8 years.<ref name="PIB" /> The bridge was inaugurated by the Union Defense Minister [[Nirmala Sitharaman]] on 18 January 2019.<ref name="PIB" />

==Significance==

Earlier, Indian Defense Forces had laid the [[Bailey bridge]] over the Diffo River. It was a temporary structure that had to be closed during most rains.<ref name="Telegraph" /> The new bridge provides uninterrupted access between Dibang Valley and Lohit valley of Eastern Arunachal Pradesh on Roing-Koron-Paya Road.<ref name="GKT"/> Lohit valley is the corridor that leads to [[Kibithu]], the battleground of the [[Sino-Indian War|1962 Indo-Sino war]] and Lower Dibang Valley leads to the [[Anini]] front of border with [[China]].<ref name="Telegraph">{{Cite web|url=https://www.telegraphindia.com/north-east/smooth-ride-to-china-border/cid/1682113|title=Smooth ride to China border|website=www.telegraphindia.com|language=en|access-date=2019-09-11}}</ref> The bridge reduced traveling time between [[Tezu]] and [[Roing]] (district headquarters of Lohit Valley and [[Lower Dibang Valley district|Lower Dibang Valley]] respectively) from 3 hours to 45 minutes. During a monsoon, the old route took travelers through [[Assam]].<ref name="Telegraph"/> Strategically, it provides an all-weather route for troops deployed on the China border ([[McMahon Line|the McMahon line]]).<ref>{{Cite web|url=https://www.defencedirecteducation.com/diffo-bridge-arunachal-pradesh-important-india/|title=Why The Diffo Bridge In Arunanchal Pradesh Is Important For India|website=www.defencedirecteducation.com|access-date=2019-09-11}}</ref>
