NEWDELHI, 17th Aug: Indian Railways in its effort to provide connectivity to various parts of the country, especially in the remote areas is taking multiple steps where transportation is still a major problem for the people living in those areas.
In one such step Indian Railways' North East Frontier Railway zone has been constructing the world's tallest pier bridge in the North-Eastern state of Manipur.
The bridge which is being constructed across river Ijei near Noney is an engineering marvel because the tallest pier height will be of 141 metres. It will surpass the existing record of 139 metres of Mala-Rijeka viaduct, Montenegro in Europe.
The bridge is a part of Jiribam-Tupul-Imphal new BG line project (111 Km). The total length of the bridge will be 703 metre. 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.
