The news
Prime Minister Narendra Modi will inaugurate the six-lane Kachchi Dargah–Raghopur–Bidupur bridge across the Ganga in Bihar on 21 November 2026. The Bihar government has named the bridge 'Nitish Setu' after former Chief Minister Nitish Kumar. Chief Minister Samrat Choudhary announced the inauguration on social media.
The 19.30 km extradosed cable bridge, built by Larsen & Toubro on 67 pillars at an estimated cost of ₹5,000 crore, includes a 9.76 km main bridge over the Ganga. A 4.57 km section between Kachchi Dargah and Raghopur Diara is already carrying traffic. The bridge is expected to provide a bypass for vehicles travelling to Muzaffarpur, Vaishali, Darbhanga, Kosi and Seemanchal without entering Patna city, and to reduce freight load on Mahatma Gandhi Setu, Bihta–Koilwar bridge and Veer Kunwar Singh Setu.
Nitish Setu bridge Bihar: why in the news?
The Bihar government has named the new Ganga bridge after former CM Nitish Kumar, and PM Modi is scheduled to inaugurate it on 21 November 2026, making it a major infrastructure and political event for the state.
What is an extradosed bridge and where was it first used in India?
An extradosed bridge is a hybrid design that combines features of a cable-stayed bridge and a box-girder bridge, with cables running from low towers to the deck but at a shallower angle, reducing the height of the towers. The first extradosed bridge in India was the Second Vivekananda Bridge in Kolkata, completed in 2007. The Narmada Bridge at Bharuch, opened in 2017, is another prominent example of this technology in the country.
What are the existing Ganga crossings in Patna?
Patna currently has two major Ganga bridges: the two-lane JP Digha Setu and the four-lane Mahatma Gandhi Setu. The new six-lane Nitish Setu will be the third major Ganga bridge connecting the city to north Bihar.
How will the bridge improve connectivity?
The bridge is planned to connect the Patna Ring Road with the under-construction Amas–Darbhanga four-lane expressway, creating a direct logistics and transport hub linking Danapur, Digha, Shivala, Bihta, Kanhauli, Dumri, Nayagaon, Telwarichak, Kachchi Dargah and Sabalpur. Officials said this will reduce travel time for north Bihar-bound vehicles and ease congestion on existing bridges.
What development plans does the government have for Raghopur Diara?
The Bihar government is working on a plan to build embankments around Raghopur Diara and is preparing to develop industrial areas, logistics zones and an IT park there. These are plans rather than completed facilities, according to officials.
