Prime Minister Narendra Modi inaugurated the Aunta–Simaria Bridge Project over the River Ganga in Begusarai district, Bihar, on 22 August 2025. Built on National Highway-31, the project is expected to significantly improve connectivity between North Bihar and South Bihar, reduce logistics costs and strengthen regional economic integration. During his Bihar visit, the Prime Minister also inaugurated and laid the foundation stone of development projects worth nearly ₹12,992 crore and flagged off the Amrit Bharat Express between Gaya and New Delhi.

The inauguration of the Aunta–Simaria Bridge represents one of the most significant transport infrastructure developments in Bihar in recent years. The bridge has been constructed parallel to the ageing Rajendra Setu, which has served as a crucial road-cum-rail link across the Ganga for decades but has become increasingly inadequate due to rising traffic volumes and restrictions on heavy commercial vehicles. The new bridge substantially enhances carrying capacity and improves the efficiency of road transport across the river. (Wikipedia)The Aunta–Simaria Bridge Project has a total length of approximately 8.15 km, including approaches, while the main six-lane bridge spans 1.86 km across the Ganga. Constructed at a cost of more than ₹1,870 crore, the project forms part of National Highway-31, a vital transport corridor connecting eastern India. The six-lane configuration provides substantially higher traffic capacity and is expected to accommodate future transport demand. (Wikipedia)A major benefit of the project is the elimination of the over 100 km detour previously undertaken by heavy vehicles due to the deteriorating condition of Rajendra Setu. The bridge establishes direct connectivity between Mokama (Patna district) and Begusarai, thereby improving freight movement between the districts of Begusarai, Supaul, Madhubani, Purnea and Araria in North Bihar and Sheikhpura, Nawada and Lakhisarai in South Bihar. Reduced travel distance will lower transportation costs, save fuel, decrease travel time and improve supply chain efficiency. (Wikipedia)The bridge is expected to contribute significantly to regional economic development. Improved road connectivity facilitates faster movement of agricultural produce, industrial goods, construction materials and consumer products. Lower logistics costs improve market accessibility for farmers and industries while encouraging private investment in manufacturing, warehousing and logistics services.The project also carries considerable importance for religious and cultural tourism. Improved access to Simaria Dham, an important pilgrimage centre situated on the banks of the Ganga and the birthplace of Rashtrakavi Ramdhari Singh Dinkar, is expected to promote tourism, hospitality and associated service industries. Better connectivity may also strengthen tourism circuits linking major destinations across Bihar.During the visit, the Prime Minister inaugurated and laid foundation stones for projects worth approximately ₹12,992 crore, covering sectors such as energy, healthcare and urban development. These projects are expected to generate employment, strengthen public infrastructure and support Bihar's long-term economic growth strategy.Another significant development was the flagging off of the Amrit Bharat Express connecting Gaya and New Delhi. The Prime Minister described Amrit Bharat as India's third modern train category, following Vande Bharat and Namo Bharat trains. According to the announcement, the train incorporates several modern safety features including Kavach, semi-automatic couplers, crash tubes and an EP-assisted braking system, while remaining affordable for ordinary passengers. The train also emphasises energy efficiency, passenger convenience, and environmental sustainability.The bridge also enhances disaster resilience by providing an alternative crossing over the Ganga. Multiple bridge connectivity improves emergency response during floods, infrastructure maintenance or traffic disruptions and strengthens overall transport redundancy across Bihar.Overall, the inauguration of the Aunta–Simaria Bridge demonstrates the growing emphasis on modern transport infrastructure, regional integration, logistics efficiency, religious tourism, and multimodal connectivity, all of which are essential for accelerating Bihar's socio-economic development.
