The Godavari Arch Bridge is a bowstring-girder bridge that spans the Godavari river in Rajahmundry, India. It is the latest of the three bridges that span the Godavari river at Rajahmundry. The Havelock Bridge being the earliest, was built in 1897, and having served its full utility, was decommissioned in 1997. 〔 The second bridge known as the Godavari Bridge is a truss bridge and is Asia's second longest railroad bridge.〔(【引用サイトリンク】title=Godavari Bridge )〕〔(【引用サイトリンク】title=Third Godavari Railway Bridge, India )〕〔Dayaratnam, pp. 219–228〕 The bridge is one of the longest span prestressed concrete arch bridge in Asia.〔 The Indian Railways who built this bridge have stated that "It is perhaps for the first time anywhere in the world that a bowstring arch girder using concrete has been constructed for such a long span of , and that too for the Railway loading."〔 It has been widely used to represent Rajahmundry in arts, media, and culture. It is one of the recognised symbols of Rajahmundry. ==Geography== The bridge is built across the Godavari River, the largest river in South India at over length. It is built in the region as the river enters into the deltaic reach before discharging into the sea downstream of the bridge. At the location of the bridge the Godavari river flows with a width of about , split in two channels with an island formation in between. The maximum discharge observed in the river is reported to be around 3 million m3/s and the maximum velocity of water flow as per second.〔 The bridge is located in a cyclonic area where the wind speed touch per hour. The bridge is located in two channels, the Kovvur channel and the Rajahmundry channel, and hence the bridge is also known as the Kovvur-Rajahmundry Bridge. The Rajahmundry channel has a deep rocky bed, and even the water level is . Comparatively the Kovur channel is shallow with a water depth of about and riverbed is made up of clay deposits. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Godavari Arch Bridge」の詳細全文を読む スポンサード リンク
