Arrah–Chhapra Bridge (orVeer Kunwar Singh Setu)[4] is the longest multi-spanextradosed bridge in the world with a main bridge length of 1,920 m (6,300 ft).[5] The bridge crosses over theGanges River inIndia, connectingArrah inBhojpur district toChhapra inSaran district ofBihar state.[6][7] The bridge provides a roadway link between the northern and southern parts of Bihar.[8] The bridge opened for public use on 11 June 2017.[9]
As of April 2021, it is the 9thlongest bridge above water inIndia. The second longest extradosed bridge isKiso-gawa bridge inJapan which is 275 m long.[citation needed]
PoliticianNitish Kumar laid thefoundation stone for the Arrah-Chhapra bridge in July 2010. He said that his wish was to connect theBhojpuri-speaking districts.[citation needed] The bridge reduced the distance between Chhapra and Arrah from 130 km to 40 km.[10] This has greatly reduce the distance of Arrah, Aurangabad and Bhabhua districts from Siwan, Chhapra and Gopalganj districts.[11] People can go from South to North Bihar without going to Patna district. This bridge connectsNH-31 atChirand nearChhapra toNH-922 atKoilwar nearArrah with a 4-lane bridge.[12][13]
The₹800 crore (US$95 million) bridge is the longest multi-spanextradosed bridge in the world.[14] The multi-span extradosed navigational section over the Ganges is 1,920m long and the bridge has a total length of 4.35 km, including the approach spans of more than 2 km. The 120m-long navigation spans are supported by five extradosedstay cables arranged in a single-plane harp configuration, whereas the approach spans are simply-supported. The navigation spans and 2 km of the approach spans are composed of single-cell precast concrete box girders, while the remaining 0.35 km of approach spans are cast-in-place. The total length of approach road on either side of the bridge is 17 km.[15]
In September 2015, seven people were killed after a crane collapsed at the bridge construction site.[16][17]
The Ganges divides the state of Bihar in two parts. The river makes communication between the two parts difficult.
The first effort to bridge the gap wasRajendra Setu in 1959. The next bridge across the Ganges in Bihar was the 5,575-metre (18,291 ft)Mahatma Gandhi Setu, the longest bridge in India at the time of its commissioning in 1982.[18] It was followed byVikramshila Setu nearBhagalpur.[19] The fourth bridge across the Ganges in the state is theDigha–Sonpur bridge.
Munger Ganga Bridge is also under construction.[20] A 5.575-kilometre-long (3.464 mi) bridgeBakhtiyarpur-Tajpur Bridge is under construction which will connectBakhtiyarpur andTajpur.[21]
Arrah–Chhapra Bridge across the Ganges connectsArrah andChhapra.[22] A road bridge parallel to the existing rail and road bridge, Rajendra Setu, has also been planned.[23]
