“Bihar’s ambitious road connectivity scheme, launched on June 17, 2025, aims to revolutionize infrastructure with over ₹30,000 crore in projects. Key initiatives include the Patna-Purnea Expressway, Buxar-Bhagalpur Expressway, and multiple Ganga bridges. Targeting completion by 2027, these projects promise reduced travel times, enhanced economic growth, and better rural-urban connectivity across the state.”
Bihar’s Infrastructure Leap Forward with New Road Projects
On June 17, 2025, the Bihar government unveiled a transformative road connectivity scheme, backed by a massive investment of over ₹30,000 crore, aimed at reshaping the state’s infrastructure landscape by 2027. This ambitious initiative, supported by the central government, focuses on constructing and upgrading highways, expressways, and bridges to boost connectivity, trade, and economic development.
The flagship projects include the Patna-Purnea Expressway, a 162-km stretch designed to slash travel time between these key cities to under three hours. Another major undertaking is the Buxar-Bhagalpur Expressway, which will connect western and eastern Bihar, integrating with the Purvanchal Expressway for seamless interstate travel. Additionally, the scheme includes spurs linking Bodhgaya, Rajgir, Vaishali, and Darbhanga, fostering tourism and economic activity in these culturally significant regions.
A key highlight is the construction of multiple bridges over the Ganga River, including a six-lane bridge at Aunta-Simarai and a two-lane bridge at Buxar. These projects, with a combined allocation of ₹26,000 crore as announced in the 2024 Union Budget, aim to address the state’s historical connectivity challenges across the Ganga, which divides Bihar into northern and southern regions. Chief Secretary Amrit Lal Meena noted, “The addition of 10 new Ganga bridges, increasing lane width from 10 to 70, will significantly enhance access to agriculture, education, and healthcare.”
The scheme also prioritizes rural connectivity under the Mukhya Mantri Gram Sampark Yojana, with plans to construct 8,000 km of rural roads to connect over 7,000 habitations. This builds on Bihar’s existing 1.2 lakh km rural road network, developed over the past two decades, which has already made the state’s road density the third highest in India. The government has also approved 21 new toll plazas and six bypasses, including those at Mangobandhar, Kendua, and Jhajha, to streamline traffic flow.
Union Minister Nitin Gadkari, during a recent visit, pledged to elevate Bihar’s national highways to global standards within four years, with an additional ₹37,000 crore allocated for projects like the Mokama-Munger four-lane highway and a ₹2,500 crore bridge over the Gandak River. The 9.76-km Kacchi Dargah–Bidupur six-lane bridge, inaugurated by Chief Minister Nitish Kumar in June 2025, is already reducing traffic congestion on the Mahatma Gandhi Setu and connecting remote areas to NH 31 and NH 322.
These developments are expected to catalyze economic growth by improving logistics for Bihar’s dominant agriculture sector, which employs 80% of the population. The state’s focus on agro-business, exemplified by the need for rapid transport of perishable goods like Muzaffarpur’s Shahi Litchi, will benefit from enhanced road networks and proposed air cargo hubs. Furthermore, the scheme aims to boost tourism by improving access to heritage sites like Bodh Gaya and Vaishali, which have historically suffered from poor connectivity.
The Bihar State Road Development Corporation Limited (BSRDCL) is overseeing key projects, such as the 9.09-km Saristabad-AIIMS elevated road in Patna, with a ₹13 billion investment. This four-lane corridor, incorporating modern construction techniques like segmental girders, will decongest urban traffic and provide seamless routes to Naubatpur, Bihta, and Paliganj. Deputy Chief Minister Vijay Kumar Sinha emphasized, “These projects are not just about roads but about connecting lives and fostering inclusive growth.”
With land acquisition for the Patna-Purnea Expressway fast-tracked under a 100-day deadline and tenders for other projects imminent, Bihar’s infrastructure boom is poised to transform the state into a connectivity hub, driving economic prosperity and improving quality of life for millions.
