Godavari Bridge
Résumé
The Godavari Bridge or Kovvur–Rajahmundry Bridge is a truss bridge spanning the Godavari River in Rajahmundry, India. It is India's third longest road-cum-rail bridge crossing a water body, the first one being the Bogibeel Bridge, also a rail-cum-road bridge over the Brahmaputra River in the Dibrugarh district of Assam state in north-east India, and second is Digha–Sonpur Bridge over Ganges in Bihar.
The Godavari bridge is 4.1 kilometers (2.8 km Rail part & 4.1 km Road part) long consisting of 27 spans of 91.5 m and 7 spans of 45.72 m of which 6 spans of 45.72m are in 6 deg. curve at long Rajahmundry end to make up for the built up area. The bridge has a road deck over the single track rail deck, similar to the Grafton Bridge in New South Wales, Australia. This bridge, in addition to Godavari Arch Bridge, has been widely used to represent Rajahmundry in arts, media, and culture. It is one of the recognised symbols of Rajahmundry.
The road-cum-rail bridge is built across the Godavari River (largest river in South India at over length) as it enters into the deltaic reach before debouching into the sea downstream of the bridge, the second largest river in India. At the location of the bridge, near Rajahmundry, the 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
During the Third Five-Year plan doubling of railway track between Chennai-Howrah was planned. Most of the route had been doubled except the small stretch of track between Kovvur and Rajahmundry where a bridge had to be built to span the three kilometer long Godavari River. During 1964, the construction of second bridge across Godavari river at Rajahmundry was sanctioned as a part of doubling of track between Kovvur and Rajahmundry. But there had been a persistent demand from local population for construction of a road link between Kovvur and Rajahmundry, which would essentially link East Godavari and West Godavari districts.
