Bridging Progress: PM Modi Unveils Bihar’s Landmark Aunta–Simaria Highway and 6-Lane Ganga Bridge

Prime Minister Narendra Modi is set to inaugurate the Aunta–Simaria highway project today, marking a transformative moment for Bihar’s infrastructure landscape. The centerpiece of this initiative is a state-of-the-art six-lane bridge over the Ganga River, designed to drastically improve connectivity between North and South Bihar. The inauguration ceremony, taking place in Simaria, Begusarai, is expected to draw national attention as the bridge stands as a symbol of engineering prowess and regional development.

Here’s a comprehensive breakdown of the project and its significance:

1. Project Overview and Strategic Importance  
- The Aunta–Simaria highway project is part of National Highway 31 and spans a total of 8.15 km, including a 1.86-km six-lane bridge across the Ganga  
- Constructed at a cost exceeding ₹1,870 crore, the bridge is India’s widest extradosed cable-stayed bridge, with a width of 34 metres and segment lengths ranging from 57 to 115 metres  
- The bridge runs parallel to the aging two-lane Rajendra Setu, which has been closed to heavy vehicles due to structural concerns  

2. Connectivity Boost Across Bihar  
- The new bridge will eliminate detours of over 100 km for freight and passenger movement, significantly reducing travel time and fuel costs  
- It links Mokama in Patna district with Begusarai, streamlining access between districts such as Supaul, Madhubani, Purnea, and Araria in the north, and Patna, Sheikhpura, Nawada, and Lakhisarai in the south  
- This improved connectivity is expected to ease congestion on other major bridges like the Mahatma Gandhi Setu  

3. Economic and Industrial Impact  
- The bridge is poised to catalyze economic activity in North Bihar, which depends heavily on South Bihar and Jharkhand for raw materials  
- Industrial hubs like Barauni will benefit from smoother freight movement, while farmers—especially makhana growers—will gain quicker access to national and international markets  
- The project is expected to enhance logistics efficiency, reduce operational costs, and attract investment in regional manufacturing and agriculture  

4. Engineering Excellence and Innovation  
- The bridge incorporates advanced construction technologies, including high-performance concrete mixed with silica fume for enhanced durability  
- A railway underpass was built using push-box technology, allowing uninterrupted train operations during construction  
- Cantilever arms extending 70 metres add to the bridge’s structural sophistication, making it a signature feat in Indian civil engineering  

5. Cultural and Tourism Significance  
- The bridge improves access to Simaria Dham, a revered pilgrimage site and the birthplace of celebrated poet Ramdhari Singh Dinkar  
- The Bihar government is actively working to develop Simaria as a cultural tourism hub, with the Kalpavas Mela drawing thousands of devotees annually  
- Enhanced infrastructure is expected to boost footfall and tourism revenue in the region  

6. Political and Developmental Context  
- PM Modi laid the foundation stone for the project in October 2017, and its completion underscores his administration’s focus on infrastructure-led growth  
- Bihar’s Road Construction Minister Nitin Navin hailed the inauguration as a milestone, emphasizing the bridge’s role in transforming Bihar’s connectivity and economic prospects  
- Chief Minister Nitish Kumar described the bridge as a testament to Bihar’s journey from the lantern age to modern infrastructure, aligning with the vision of making Bihar a growth engine for India  

7. What’s Next  
- During his visit to Bihar, PM Modi is also expected to lay the foundation for other development projects worth ₹13,000 crore and flag off two new trains  
- These initiatives are part of a broader push to modernize Bihar’s transport, energy, and civic infrastructure ahead of the upcoming state assembly elections
