Today, Prime Minister Narendra Modi is on a visit to Assam where to inaugurate the Dhola-Sadiya bridge over Lohit, which is a tributary of river Brahmaputra. At 9.15 km, it is the longest bridge in India, and one of the most important infrastructure projects of India. The bridge will revolutionize road transport in north-east, improve connectivity and is a huge boost to the country strategically.
1. The state of the art Dhola-Sadiya bridge has a three lane road.The total length of the bridge is 9.15 kilometre, making it India’s longest bridge. The total length of the Dhola-Sadiya bridge project is 28.50 km if the approach roads on both sides are included. It is built over river Lohit, a tributary of the Brahmaputra.
2. The bridge links Dhola in Assam to Sadiya in Arunachal Pradesh. Before the bridge the only possible way to cross this area was by boats and ferries. During monsoons and floods, even the ferry services were stopped thereby completing putting an end to any means to cross the river. The Dhola- Sadiya bridge will ensure 24X7 connectivity between upper Assam and the eastern part of Arunachal Pradesh.
3. The bridge will reduce the distance from Rupai on NH-37 in Assam to Meka/Roing on NH-52 in Arunachal Pradesh by 165 kilometre, cutting down on travel time from the current six hours to just one hour. Reducing the travel time to strategically important Arunachal Pradesh by 5 hours is extremely important for strategic purposes.
4. Due to reduction in distance between the two cities in the northeast by 165 kilometre, the government claims it will result in saving of petrol+diesel worth Rs 10 lakh per day.
5. The bridge is an engineering marvel in many aspects. The bridge has 182 piers. Since the northeast of India is prone to high seismic activity, there are seismic buffers in all 182 piers of the bridge.
6. The construction of the entire bridge project (including the approach roads) was completed at a total cost of Rs 2,056 crore. The Dhola-Sadiya bridge is part of the Arunachal Package of Roads and Highways under the Ministry’s Special Accelerated Road Development Programme for North East.
7. The Dhola-Sadiya bridge promises to provide efficient road connectivity to remote and backward areas which have poor road infrastructure, which will give a major boost to overall economic development of the areas north of the Brahmaputra in upper Assam and Arunachal Pradesh.
8. The bridge will give a major boost to the army, with convoys requiring less time to journey from Assam to the posts along the India-China border in Arunachal Pradesh. The bridge is capable of transporting heavy military vehicles and tanks. This will strengthen India’s defense in the much-needed Arunachal region.
Apart from this, the bridge will open many avenues for development in Arunachal Pradesh, as the traveling time has been cut by more than 5 hours. This will promote investment and industrialization of the area. Also, many power projects are set to come up in the area. With the opening of this bridge, all these projects are soon going to be accelerated.
