Dhola-Sadia Bridge is Longest Bridge of India

Prime Minister Narendra Modi dedicated the Dhola- Sadia bridge in Assam to the nation.

The length of the bridge is 9.16 kilometres and this will be longest bridge of the country.

The 1200 crore rupees bridge will give a boost to the connectivity for the people of Assam and Arunachal Pradesh.

The Dhola–Sadiya Bridge spans the Lohit River to connect the states of Assam and Arunachal Pradesh.

Construction began in 2011 under the aegis of the Ministry of Road Transport and Highways in public private partnership (PPP) with Navayuga Engineering Company Ltd.

It is 3.55 kilometres (2.21 mi) longer than the Bandra Worli Sea Link in Mumbai, making it the longest bridge in India.

Basic features of the project:

Construction of 9.15-kilometre-long, 12.9-metre-wide bridge on river Brahmaputra between Dhola and Sadia Ghats.

Realignment of the existing road on Dhola side of 7.297 km, improvement to existing single lane road to double lane with paved shoulder on Sadia side of 11.874 km.

For the Brahmaputra river after Kaliabor bridge in Central Assam throughout the 375 km of river bank there is no bridge for transportation across Mighty Brahmaputra river. In the upstream after 120 km there is a bridge available for crossing the same but it travels through difficult hilly tarrain on north bank. At present all the transport are being carried out through water only. Hence this Dhola Sadiya bridge project will enhance the entire transport system of North Assam.

This project serves important logistics for Military personnel for Indo China border at Arunachal Pradesh.

The Union Government has decided to name the Dhola-Sadiya bridge after the great musician, lyricist and poet, Bhupen Hazarika.
