State and Centre join forces to fast-track river crossingsPatna: Bihar is embarking on one of its most ambitious infrastructure expansions in recent years, with plans to build a total of 51 bridges across four major rivers the Ganga, Son, Kosi and Gandak. The initiative, backed jointly by the state government and the Centre, aims to ease long-standing connectivity challenges in a region defined by its riverine geography.
Rivers have historically shaped Bihar’s economy and culture, but they have also hindered seamless movement between districts, particularly between north and south Bihar. Under the leadership of chief minister Nitish Kumar, the state government says it is seeking to transform this challenge into an opportunity by accelerating bridge construction and upgrading existing crossings.
According to the road construction minister, Dilip Kumar Jaiswal, 25 bridges are currently operational across the four rivers. Construction is under way on 14 additional projects, while 12 more are set to begin soon. Officials say the expanded network will significantly reduce travel time, lower transport costs and stimulate economic activity across rural and urban areas alike.
Major focus on the Ganga
The largest concentration of projects is centred on the Ganga, widely regarded as the state’s lifeline. Eight bridges are currently operational over the river, with eight more under construction. Key projects include parallel expansions to the Mahatma Gandhi Setu and JP Setu, as well as the six-lane Kachchi Dargah–Bidupur Bridge.
A parallel four-lane structure is also being developed alongside the Vikramshila Setu, while additional bridges on the Bakhtiyarpur–Tajpur stretch and at Munger, Matihani–Shamho and Kahalgaon are expected to narrow the physical and economic divide between the two halves of the state.
Gandak and Kosi crossings expand
Seven bridges are currently operational over the Gandak river, with new projects planned from Hajipur towards the Valmiki region. A proposed six-lane bridge under the Gorakhpur–Siliguri expressway and a four-lane crossing at Sattarghat on the Ram-Janaki corridor are expected to strengthen connectivity in north Bihar.
The Kosi river, often referred to as the “sorrow of Bihar” because of its history of flooding, has five operational bridges. Construction is under way at Bheja–Bakaur and Phulaut, while a six-lane bridge near Simri Bakhtiyarpur on the Patna–Purnia corridor is anticipated to benefit the Seemanchal region in particular.
Industrial boost along the Son
The Son river currently has five operational bridges, with a two-lane project under construction at Panduka. Additional crossings are planned under the Varanasi–Ranchi–Kolkata corridor and along the Patna–Ara–Sasaram route, which officials say will play a key role in supporting industrial growth in south and west Bihar.
Government officials argue that once completed, the 51-bridge network will reduce fuel consumption, shorten supply chains and make it easier for farmers and small businesses to access larger markets. For a state long shaped and constrained by its rivers, the coming years may mark a decisive shift in how people and goods move across Bihar.
