The Trans-Arunachal Highway, passing through the entire length of the state, roughly divides Arunachal Pradesh state in two parts - the upper two-third in north and east and lower one-third. At least 1811 km route already exists as national highway, and remaining are either greenfield or an upgrade of existing routes to national highway standard. It starts from India's north most military post (north of Hathung La Ridge) in Tawang district, goes via Zemithang, Tawang, Bomdila, Nechipu, Seppa, Sagalee, Yupia, Yazali, Ziro, Daporijo, Aalo, Pasighat, southern part of Dibang Valley district, Lohit, Roing, Tezu, Mahadevpur, Bordumsa, Namchik, Changlang, Khonsa, Longding, and ends at Kanubari.

The Trans-Arunachal Highway greatly helps in reducing isolation of the people by connecting the district headquarters, major hydro electric power projects and other important places. Trans-Arunachal Highway, along with the under-construction Arunachal East-West Corridor across the lower foothills inside Arunachal Pradesh along the Assam border and the proposed Arunachal Frontier Highway along the China border, are important enablers of Northeast development and India's Look East connectivity strategy. This strategically important highway network enhances Indian military's capabilities in combating the threat of China's Western Theater Command opposite India's eastern sector of Line of Actual Control.

In October 2022, 1,458 km long route was complete and already operational. TAH, from Tawang to Kanubari in Longding district has a target completion date of March 2024.

History
