Hindustan Construction (HCC) and Welding Research Institute (WRI), a unit of Bharat Heavy Electricals Limited (BHEL), have signed a memorandum of understanding (MoU) to build India’s longest railway bridge, over the river Brahmaputra, for INR32.3bn ($604m).
Scheduled to be completed by 2015, the new rail / road strategic bridge will link the Indian states of Assam and Arunachal Pradesh.
WRI, which will use new welding techniques to complete the bogey wheel project, will provide welding consultancy, procedure development, inspection and distortion control, training of welding engineers, supervisors and welders as per European standards.
The double-deck bridge will span 4.315 km, allowing a three-lane road on the upper deck, which will be built 10.5m over the rail tracks, and construction of two railway tracks on the lower deck.
HCC said the bridge will be fourth largest in the country and the longest bridge over the Brahmaputra River.
HCC has a 51% share, while DSD Brouckenbau has 20% and VNR Infrastructures 29%.
As part of the project, a 74km of rail link will be built, while the road will be connected to national highway 37 on the south bank of the Brahmaputra and national highway 52 on the north bank.
