Why Is the Amas Darbhanga Expressway Important for Bihar?
Bihar has historically lacked high-speed, access-controlled highways. The Amas Darbhanga Expressway changes that by:
- Linking NH-19 (Delhi–Kolkata corridor) to NH-27
- Integrating with Patna Outer Ring Road
- Connecting key urban, agricultural, and industrial zones
- Reducing dependency on congested city roads
This expressway positions Bihar closer to infrastructure standards seen in states like Uttar Pradesh and Maharashtra.
