<p>The Railways have achieved a ‘major milestone’ with the construction of a 100-meter-plus tall pier in the World’s tallest railway bridge being constructed near Noney in Manipur.</p>.<p>The bridge is being constructed over Ijai river near Noney as part of the 111-km Jiribam-Tupul-Imphal new broad gauge railway project, under Northeast Frontier Railways (NFR). The pier with a height of 141-meter will surpass the existing record of 139-meter of Mala-Rijeka viaduct near Montenegro in Europe. The total length of the bridge will be 703-meter, senior public relations officer of NFR Construction Organization, S. K Ojah said, in a statement.</p>.<p>“The piers of the bridge are constructed using hydraulic augers, the tall piers needed specially designed “slip-form technique” to ensure efficient and continual construction. “Self-erecting” electric lifts at each pier cater to the safe and speedy conveyance of men and materials to the top. The steel girders are pre-fabricated in a workshop, transported in segments and erected at the site by cantilever launching scheme,” Ojah said.</p>.<p>Construction work of the project began in 2014 and picked up momentum in the last three years after it was declared a national project. “There are total 45 tunnels in the project--longest being 10.28-kilometre. This will be the longest railway tunnel in the Northeast,” he said.</p>.<p>The alignment of the railway line passes through steep rolling hills of the Patkai region in the eastern trail of the Himalayas. Jiriban, a small town situated along Assam-Manipur border is located at 37-meter above mean sea level while Imphal, Manipur capital is situated at 780-meter above mean sea level. It was decided to construct the tunnels of 54-km to maintain suitable gradient as the alignment will traverse through several deep gorges and several rivers flowing at low ground level.</p>.<p>A.Saibaba, chief engineer of NFR, Construction is in-charge of the project, Ojah said.</p>
