SAIL supplies 35,400 tonnes steel for Bogibeel Bridge construction

Prime Minister Narendra Modi at the dedication of the India’s longest Bogibeel Bridge to the nation, at Dibrugarh, Assam on December 25. Governor of Assam Jagdish Mukhi and Chief Minister Sarbananda Sonowal are also seen.
THE country’s largest steel maker SAIL on said it has supplied 35,400 tonne of steel for the construction of Bogibeel, Asia’s second-longest rail-cum-road bridge that was inaugurated to traffic by Prime Minister Narendra Modi on December 25.
“Steel Authority of India Ltd (SAIL) has supplied around 35,400 metric tonnes of steel for the construction of Bogibeel road-cum-rail bridge on the river Brahmaputra,” the PSU said in a statement. The quantity, it said, is little over 50 percent of the total...
steel supplied for the bridge.
“SAIL has supplied TMT rebars, plates and structurals for this 4.94-km long bridge, which has composite welded steel truss girders in its structures,” it said. The 4.9 km-long Bogibeel Bridge on the Brahmaputra river has been constructed at Rs 5,900 crore.
The bridge reduces travel time from Assam to Arunachal Pradesh to four hours and will cut out the detour of over 170 km via Tinsukia. It will also reduce Delhi to Dibrugarh train travel time by about three hours to 34 hours as against 37 hours currently.
Earlier, SAIL also supplied around 90 percent or around 30,000 tonnes of steel, including TMT, structurals and plates, for the Dhola-Sadiya Bridge in Assam, India's longest river bridge. This bridge was also inaugurated by Prime Minister Modi on May 25 this year.
The Bogibeel Bridge in Assam has a two-line railway track on the lower deck and a three-lane road on the top deck. It will reduce the Delhi to Dibrugarh train travel time by about three hours.
10 things you should know about the Bogibeel Bridge:
Designed like a bridge that links Sweden and Denmark, the Bogibeel Bridge is India's only fully-welded bridge for which European codes and welding standards were followed. A fully welded bridge has a low maintenance costs, its engineers say.
The bridge, which also happens to be Asia's second longest rail-and-road connector, has a lifespan of around 120 years, authorities have said.
The bridge has a two-line railway track on the lower deck and a three-lane road on the top deck. It will reduce the Delhi to Dibrugarh train travel time by about three hours.
Inaugurating the bridge, PM Modi will also flag off a train - the Tinsukia-Naharlagun Intercity Express, which will run five days a week.
The 4.9 km-long bridge was constructed at an estimated cost of Rs. 5,900 crore - exceeding its initial budget of about Rs. 3,200 crore and originally planned length of 4.31 km.
The foundation stone of the project was laid by former Prime Minister HD Deve Gowda on January 22, 1997, while work began on April 21, 2002 under the Atal Bihari Vajpayee-led government. December 25 happens to be Vajpayee's birth anniversary.
"Early flood in the river Brahmaputra restricted the working season to a very short period of approximately five months - from November to March - and demanded huge mobilization of construction equipment," Chief Engineer Mohinder Singh told news agency PTI, explaining the delay in the project.
The project took 30 lakh bags of cement - enough to fill more than 41 Olympic swimming pools and 19,250 metres of reinforcement steel - well over twice the height of Mount Everest.
The bridge will be a massive help for residents of the remote districts of Anjaw, Changlang, Lohit, Lower Dibang Valley, Dibang Valley and Tirap in Arunachal Pradesh besides the Dibrugarh and Dhemaji districts in Assam.
The Bogibeel Bridge is likely to play an important role in defence movement along the India-China border in Arunachal Pradesh. The three road lanes of the bridge can act as three landing strips for the Air Force.
