GUWAHATI: Railway Minister Suresh Prabhu has assured that construction of the Bogibeel Bridge would be completed during 2017-18. Prabhu informed about this to Governor Banwarilal Purohit in a letter.
The Governor had earlier written a letter to Prime Minister Narendra Modi requesting the PMO’s intervention in expediting the construction of the Bogibeel Bridge.
Prabhu mentioned that all the 42 well foundations and piers of the main bridge have been completed. Work of both north and south guide bunds, of rail link from Chaulkhowa to Moranhat, along with connectivity on North and South banks have also been completed, he said. Presently, the work of main bridge superstructure is in progress and 35 girders out of 41 have already been launched.
Moreover deck slab concreting has commenced from North bank which is in the process of connecting the South soon, Prabhu informed Purohit. The Bogibeel rail-cum-road bridge project was a part of the Assam Accord. The bridge project was sanctioned in the year 1997 and was declared as a National Project in 2007.
The total project cost is estimated at around Rs 5,000 crore. The bridge site is 17 km downstream of Dibrugarh. It connects Silapathar in Dhemaji district on the north bank of Brahmaputra and Bogibeel in Dibrugarh district on the south bank.
The design of Bogibeel bridge has 39 Nos.of 125 metres (410 ft) spans and a superstructure of composite welded steel truss and reinforced concrete. It is designed to carry a double line broad gauge railway on the lower deck and a 3-lane road on the upper deck. Upon completion it will be the longest bridge over the Brahmaputra and the longest combined rail and road bridge in India. However, due to late completion this bridge may be overtaken as longest bridge over Brahmaputra by Dhola-Sadiya Bridge which is a road bridge of length 9.15 km.
Bogibeel bridge will provide a connection between the Rangia-Murkongselek section of the North East Frontier Railwayon the north bank of Brahmaputra and Lumding–Dibrugarh section that lies to the south of the Brahmaputra. A New Dibrugarh Railway Station, expected to be the largest in the region, has been proposed and is to be linked to the Rangia – Murkongselek line via Chaulkhowa and Moranhat. The Railways have initiated the gauge conversion of the Dhamalgaon to Sisiborgaon rail line to the north of the bridge and commissioned the 44-kilometre-long (27 mi) Chalkhowa – Moranhat line to the south.
