Cabinet clears ₹3,590.73-crore 4-laning of Muzaffarpur–Sitamarhi–Sonbarsa NH-22

The 4-laning of NH-22 in Bihar: what happened?

North Bihar’s roads to the Nepal border are crowded and slow. This highway connects the border at Sonbarsa with Muzaffarpur, which sits on the East-West Corridor. Faster movement helps trade, pilgrims and farm produce.

• The project has seven major bridges, including a 340 m bridge over the Bagmati, three ROBs and two flyovers.
• It will cut congestion in Muzaffarpur, Runni Saidpur, Dumra, Bhutahi, Sonbarsa and other towns.
• It improves cross-border movement via the land port at Bhithamore.
• It links to Punaura Dham in Sitamarhi and the Buddhist Circuit.

How does it fit the network?

• It is planned on PM GatiShakti National Master Plan principles.
• It works with NH-31 and NH-122 and improves access to Barauni’s industrial zone and Ganga logistics hubs.
• It links five GatiShakti economic nodes, including four industrial estates and one mega food park.

Why does the 4-laning of NH-22 in Bihar matter?

• Connectivity: Faster access to the India-Nepal border.
• Economy: Links industrial and farm nodes to freight corridors.
