Longest Bridge in India: The Top 10 Longest Bridges of the Country

longest bridge in india

India is a land of many rivers and water bodies. The rivers play a crucial role in supporting the country’s large population. Not only do they provide the water for irrigation purposes, they also provide water for regular usage in cities, towns and villages. As there are many rivers in India, there are also many bridges across the country. Some of the bridges are actually quite long. The longest bridge in India is the Dhola-Sadiya bridge in Assam. However, the 9.15 kms long bridge will soon be dwarfed by the proposed 19.3 kms long Assam Meghalaya bridge. The new bridge over the river Brahmaputra, which was recently commissioned by Prime Minister Narendra Modi is likely to be completed by the year 2026-27. The bridge, which will become the longest bridge in the country, will run between Dhubri in Assam and Phulbari in Meghalaya, located very close to the Bangladesh border. The new bridge was inaugurated within a year of the opening of the longest river bridge in India, Dhola-Sadiya, in the state of Assam. The Modi government has announced plans for an extended bridge. This bridge will also be over the river Brahmaputra. Coincidentally, this announcement was made by the Indian Government just before the world’s longest sea bridge opened between Hong Kong and the Chinese mainland. The new bridge, which will become the longest bridge in India, will be completed by the year 2026-27. The bridge will span a distance of 19.3 kms between Dhubri in Assam and Phulbari in Meghalaya. The new bridge will be more than twice as long as the current longest bridge in India, the Dhola-Sadiya bridge. 

Currently, the people in Dhubri and Phulbari cross the river either in small boats or by vehicles that need to drive an extra 100 kms before climbing the Naranarayan bridge. According to an official of the Assam’s Public Works Department, four lanes have been proposed for the project. A detailed project report is being prepared by the Ministry of Road Transport and Highways through the National Highways and Industrial Development Corporation Limited (NICL) and an initial loan amount has been approved by the Japanese funding agency, JICA. While we wait for this super-bridge to finish building, let’s look at the current longest bridges in India.

Which is the Longest Bridge in India?

Dhola Sadiya Bridge: 9.15 Km, Assam

Dhola Sadiya bridge, also referred to as the Bhupen Hazarika Setu is the longest bridge in India.

It is Asia’s 2nd longest rail cum road bridge and features a serviceable period of around 120 years.

Vikramshila Setu: 4.7 Km, Bihar

The Vembanad Rail Bridge is also one of the most beautiful bridges in Kerala. This bridge allows only 15 trains to pass every day. Vembanad Lake is the largest lake in Kerala, and one of the biggest in India as well. It also hosts the Nehru Trophy Snake Boat race.

Digha Sonpur Bridge: 4.55 Km, Bihar

Another long bridge of Bihar, the Digha Sonpur Rail Road Bridge is also known as J.P Setu. Digha Sonpur rail road Bridge is a recently constructed bridge across the river Ganga, connecting Digha Ghat and Pahleja Ghat in Bihar.
