It is marked to connect Sherpur to the Patna Ring Road, which will sanction a direct entry from the Patna-Purnia Expressway to Danapur.  

Project Scope

The Greenfield Expressway is a six-lane, 90-meter-wide expressway connecting Patna to Purnia. The highways will comprise bridges, underpasses, interchanges and railway overbridges. It aims to improve road connectivity between Patna and Purnia. 

• Reducing Time Travel: The Patna Purnia Expressway intends to improve road connectivity between Patna and Purnia. As a result, travel time from Patna to Purnia will reduce. It will only take three hours to travel, once the expressway is built.

• Boosting Economy: The expressway connects rural and riparian areas, making it easy to access the market, services, and the metropolis. It opens the door for trade and industrial growth and focuses on net economic growth.

• Length: The expressway stretches to 282 km. At first, it was 250 km, but an additional 32 km was approved. 

• Blueprint. It will be a 90-meter-wide highway with an expected speed of 120km/hr. 

• Framework: It will include 21 big bridges, 140 portable bridges, 11 Railway Overbridges, 21 interchanges, and 32 underpasses.

The selection process of the contractors will be done right after the preparation of the DPR and the bidding process.

Patna Purnia Expressway Investors

The primary funding source for the six-lane expressway is the Government of India. The 2024 Union Budget shows that Finance Minister Nirmala Sitharaman announced an investment of INR 26,000 for expressways development projects in Bihar. The investment includes the Patna Purnia expressway, too. 

Benefits

The Patna Purnia Expressway will prove to be a milestone for Bihar. It's part of the larger plan to improve Bihar’s roads. The infrastructure development will ensure a reduced travel time. Along with that, it will improve connectivity and foster economic growth. Once ready, it will boost trade, tourism and investment in the state.

Reduced Time Travel

• Fewer stops and blocks: Less intersections and sharp turns make travel easier and quicker.
• High-speed design: The roads have a 120km/hr speed limit. Thus, reducing travel time by allowing vehicles to move evenly at a consistent speed.

Improved connectivity 

• Enter the underdeveloped areas: The connection to the Kosi and Seemanchal regions will provide opportunities for economic growth and infrastructural development. 
• District blend: It passes through seven districts -  Vaishali, Muzaffarpur, Madhubani, Darbhanga, Samastipur, Saharsa, and Madhepura, tying them together for better interlinkage. 

Drastic transformation in the regions this expressway passes

• Trade and logistics boost: The regions like Kosi and Seemanchal are underdeveloped. On completion of the expressway, these regions will gain faster access to Patna’s markets. As a result, it will enable quick transfer of perishable goods.
• Urbanization: Towns like Bidupur, Patepur, and Dagarua are foreseeable to grow into urban centres as people migrate for jobs and services.
• Easy access to Healthcare and Education: Natives of hinterland areas like Madepura and Darbhanga will be able to reach Patna in a shorter time. Thus, making it easy for them to access healthcare facilities and education effortlessly.
• Pollution Trade-off: The expressway might increase traffic in the regions. Along with that, it increases noise and air pollution. Yet, modern design elements like protective fencing and potential green initiatives might mitigate this. 

Other benefits

• Improved connectivity: The improved connectivity will attract more commercial and residential real estate investments.
• Infrastructure in investments: The government allocates INR 26000 crore for infrastructure development in Bihar. Such investments lead to real estate development as infrastructure attracts developers and buyers. 
• Urbanization: Urbanization leads to the development of new townships and housing projects. It diversifies real estate options and serves a larger scope of buyers and investors.

Land near the expressway could see a rise in prices: Property values near infrastructure projects see a vast jump in prices. Property owners and investors near the expressway may expect significant returns.
