- Dhola-Sadiya bridge in Assam likely to be inaugurated next year
- A little over 9 km long - 30% longer than Mumbai's Bandra-Worli Sea Link
- Will cut travel time between Assam, Arunachal Pradesh by up to 4 hours
Here is your 10-point guide to the bridge that is in the final stages of construction:
The Dhola-Sadiya bridge is being built over the Lohit river, a tributary of the Brahmaputra.
In Assam, the bridge is located in Sadia, 540 kilometres from the state capital of Guwahati. Its other end is in Dhola, 300 kilometres from Itanagar, the capital of Arunachal.
It is a little over nine kilometres long - that's nearly 30 per cent longer that the famous Bandra-Worli Sealink in Mumbai.
Once opened, the bridge will reduce travel time between Assam and Arunachal Pradesh by up to four hours. There is no operational airport in Arunachal.
Construction began in 2011, when the Congress governed Assam. The cost of the project is about 950 crores.
So far, there is little road connectivity between Assam and Arunachal. Currently, the only route for people looking to travel from this part of Assam to Arunachal is by boat.
Its strategic importance for the military is huge. With the bridge, troops will be able to enter Arunachal Pradesh, which borders China, much more quickly and easily.
The bridge has been designed to accommodate the movement of tanks.
There is no existing bridge in the region that is strong enough to allow the travel of tanks to Tinsukia, from where troops usually enter Arunachal.
Construction of this bridge was included in 15,000 crore package sanctioned by the centre in 2015 to improve road connectivity in the border state.
