GUWAHATI, May 15 - Work at the Bogibeel rail-cum-road bridge is at the final stages and is expected to be completed by December.
“Presently, work on the main bridge superstructure is in progress... All the work is planned for completion by December,” Nripen Bhattacharya, Public Relations Officer (PRO) of the Maligaon-headquartered Northeast Frontier Railway (NFR), told The Assam Tribune here today.
He added, “In all, 32 normal spans out of 39 and one shore span have already been launched. The launching is being done by incremental launching method which is designed by M/S DSD of Germany and consists of four trains. The first, second and third trains consist of 10 girders each and the fourth train consists of nine girders. The first and second trains with 10 girders each have already reached the north bank. Deck slab concreting has commenced from the north bank. Five deck slabs have been cast and another slab will be cast in a few days.”
At 4.94 km, the Bogibeel rail-cum-road bridge will be the longest bridge over the Brahmaputra and also the longest rail-cum-road bridge in India.
Bhattacharya said that work on the substructure, the guide bunds, approach embankments and dykes on both banks are complete.
“Work on the main bridge superstructure, approach track linking and balance portion of road viaducts are in progress,” said the NFR PRO.
The Bogibeel rail-cum-road bridge project was a part of the Assam Accord. The bridge project was sanctioned in 1997 and was declared as a National Project in 2007.
Bhattacharya said that the estimated cost of the project is Rs 4,857 crore. The bridge site is 17 kms downstream of Dibrugarh. It connects Silapathar in Dhemaji district on the north bank of the Brahmaputra and Bogibeel in Dibrugarh district on the south bank.
“Due to unavailability of permanent natural banks at the bridge location, guide bunds have been provided on both ends of the bridge. There are 2,043 metres of guide bunds on the south bank and 2,792 metres on the north bank,” said Bhattacharya.
