Bihar NH-22 corridor approved for ₹3,590 crore four-laning

The Cabinet Committee on Economic Affairs, chaired by Prime Minister Narendra Modi, has approved the four-laning of the 82.578-km Muzaffarpur-Sitamarhi-Sonbarsa section of National Highway 22 in Bihar. The project carries a total capital cost of ₹3,590.73 crore and will be implemented under the Hybrid Annuity Mode (HAM).

The upgraded corridor is designed to strengthen connectivity between Muzaffarpur and the India-Nepal border at Sonbarsa. By linking the border corridor to the wider national highway network, including NH-27, the project aims to facilitate smoother cross-border passenger and cargo movement through the Bhithamore Land Port.

Aligned with the PM GatiShakti National Master Plan, the infrastructure will improve access to industrial, railway, and logistics nodes, as well as cultural destinations like the Buddhist Circuit and Punaura Dham. The project includes seven major bridges, including a 340-metre bridge over the Bagmati River, and is engineered for a maximum speed of 100 kmph to enhance safety and reduce travel time.
