Maligaon, January 31 (MExN): Northeast Frontier Railway (NFR) has commissioned a new Road Over Bridge (ROB) at Mangal Bazar area in Katihar of Bihar. This bridge is the longest Bow String Girder ROB of Katihar division with 72 m span. The newly constructed ROB was inaugurated by Deputy Chief Minister of Bihar, Tarkishore Prasad in presence of Shri Dulal Chandra Goswami, MP (Lok Sabha) on 28th January, 2022.
This newly constructed ROB replaced the old and dilapidated ROB at Katihar (Mangal Bazar) which was constructed in 1964 and had outlived its life. It took 13.4 hours of engineering effort to launch it with minimal disruption to railway traffic. Due to its unique design and difficult location, this project was difficult to complete. The construction work of the two-lane ROB was started in the last month of 2019; but due to Corona pandemic the construction work of this bridge got interrupted.
This newly built infrastructure is capable of carrying load of heavy vehicles. The bridge has capacity to easily bear 12 ton / axle load and it has also been tested for bearing 20 ton / axle load. Made of steel material in arched shape, this bridge is one of the finest bow-string girder bridges of Indian Railways. The approach of both its sides is about 250 meters - 140 meters and its width is 12.5 meters.
This was stated in a press release issued by Guneet Kaur, Chief Public Relations Officer, NFR.
