The tallest railway bridge of the world in Manipur will be constructed by the Northeast Frontier Railway. The 141-m bridge is part of a new broad gauge line being constructed to connect the northeastern state with the rest of the country.
As reported, the bridge is being constructed across the valley of River Ijai and is part of the 111-km-long Jiribam-Tupul-Imphal new broad gauge line project in Manipur. The total length of the bridge is expected to be 703 m and the piers of the bridge are reportedly constructed using hydraulic augers.
Surpassing the existing record of 138 m Mala-Rijeka viaduct at Montenegro in Europe, the piers of the Manipur bridge are reportedly designed with the help of slip-form technique to ensure efficient and continual construction. The steel girders, which are pre-fabricated in a workshop, are transported in segments and erected at the site by cantilever launching scheme. Also, self-erecting electric lifts are used at each pier for the safe and speedy conveyance of men and materials to the top. With a total of 45 tunnels in the project, the tunnel’s length is reported to be 10.280 m, thus making it the longest railway tunnel in the northeast.
