The Amas Darbhanga Expressway, officially known as NH-119D, is one of the most ambitious infrastructure projects in Bihar. Approved under the Bharatmala Pariyojna and developed by the National Highways Authority of India (NHAI), this six-lane access-controlled expressway will cover a distance of nearly 189 kilometres. The project aims to connect Amas in Gaya district with Bela Nawada in Darbhanga district, creating a seamless north-south road corridor across Bihar.

With an estimated cost of ₹5,000 crore, the expressway will be constructed under the Hybrid Annuity Model (HAM). If the construction progresses as planned, the Amas Darbhanga Expressway is expected to be completed by the end of 2025.
