India’s longest bridges

A year after India’s longest river bridge was opened in Assam, the government has announced plans for a longer bridge, again over the Brahmaputra. The announcement came ahead of the opening of the world’s longest sea bridge, between the Chinese mainland and Hong Kong.

The new bridge over the Brahmaputra, proposed for completion by 2026-27, will run between Dhubri in Assam and Phulbari in Meghalaya, close to the Bangladesh border. At 19.3 km, it will be twice as long as the Dhola-Sadiya bridge, which is currently the longest.

Here are some of the numbers that define the country’s longest bridges:

19.3 km – The proposed new bridge, between Dhubri and Phulbari. At present, people cross the river either in small boats and by vehicles that have to take a detour of 100 km before climbing the Naranarayan bridge.

9.15 km – The country’s longest river bridge, as of now. Between Dhola and Sadiya in Assam, it extends to 28.50 km if the approach roads on either side are included. It reduces the distance from Rupai (Assam) to Roing (Arunachal Pradesh) by 165 km, and travel time from 6 hours to 1 hour.

6.2 km – In Arunachal Pradesh, over the river Dibang, opened this year. Second only to Dhola-Sadiya bridge so far.

5.75 km – Patna-Hajipur, over the Ganga, next on the list of river bridges

5.6 km – Bandra Worli Sea Link in Mumbai, longest bridge over sea

4.94 km – To be opened this year, India’s longest rail-cum-road river bridge (the river bridges above are all road). This bridge, too, will be over the Brahmaputra, connecting Dibrugarh (Assam) to Pasighat (Arunachal).
