Manipur shall soon have the world’s tallest rail girder bridge with the completion of the Bridge No 164 on the new Jiribam-Imphal broad gauge line in Manipur. Officials at the Northeast Frontier Railway (NFR) Construction Organization said the Rs 450-crore bridge would be ready by June 2019.
SK Ojah, Senior Public Relations Officer (SPRO) of the NFR (Construction), said that once the bridge is completed, it will attain the status of the world’s tallest rail girder bridge. It will have a pier height of 141 metres, which will surpass the existing record of 139 metres of the Mala-Rijeka viaduct at Montenegro in south-eastern Europe.
The entire engineering of Bridge No 164–right from conceptualization to detailed design and construction–has been done indigenously by the NFR (Construction). The length of the bridge will be 703 metres. The material requirements for the bridge include 65,000 cubic metres of concrete, 12,000 tonnes of reinforced steel and 600 tonnes of high tensile steel for girders to add greater strength and resistance to dynamic forces caused by moving trains.
A laboratory at the site has been established to test and pass all the material that are being used in the bridge construction. Experts from outside are also being consulted for double-checking the quality control system. The new railway line cuts across the lower Himalayan ranges, necessitating construction of a series of tunnels through the hills and tall bridges across the deep valleys.
