The Amarda Road airstrip, as it was called in war terminology, spreads across an area of nearly 900 acres.

As an airfield, Amarda Road fell on the supply route for the Nationalist Armies of China in their fight against the Japanese.

Aircraft of the RAF and the United States Army Air Forces (USAAF) would regularly fly from this space to China via Chabua (Dibrugarh), Jorhat and Vijaynagar across the infamous hump route over Arunachal and East Tibet.

Amarda Road and other neighbouring airfields - Dhalbhumgarh, Dudhkundi, Salua, Digri, Salbani and Chakulia - formed a web of airfields created by the Allies to stop the impending Japanese advance in the east.

Eight decades after the base was built, the 11,000 feet (3,400 m) concrete runway is still intact, though the buildings that once cluttered the edges are gone.
