The Trans-Arunachal Highway, also called NH13, is an under upgradation two-lane highway project in the Indian state of Arunachal Pradesh. The highway extends from Tawang in the western part of the state to Kanubari in the east covering 1,559 km. The highway is envisaged to touch eleven of the existing district headquarters. The remaining five districts and the state capital will be connected to the "Trans-Arunachal Highway" by link roads which covers another 848 km.
The Trans-Arunachal Highway, a trunk route of about 1811 km in length, would be developed to 2-lane NH standards to link Tawang in north-western tip of Arunachal Pradesh to Kanubari in south-eastern end of the State and finally ending on NH-52 near Akajan on the right side of Bogibeel bridge near Dibrugarh in Assam. The Highway, passing through the mid belt of the State, will inter-connect 12 out of total 16 district headquarters towns of the State and would thus provide improved connectivity to the state capital and important locations of population concentration and economic activities including the sites of major hydro electric power projects. Within Arunachal Pradesh, the Highway will connect the district headquarters and other important places such as Tawang, Bomdila , Nechipu, Seppa, Sagalee, Yupia, Yazali, Ziro, Daporijo, Along, Pasighat, Roing, Tezu, Mahadevpur, Bordumsa, Namchik, Changlang, Khonsa, Longding, Kanubari etc. and help greatly in reducing isolation of the people of the state. Out of about 1811 km of the Highway, about 290 km forms part of NH-52 and 10 km of NH-153. A length of about 1,850-km including link roads of Trans- Arunachal Highway has been declared as National Highway NH 52B ) by the Ministry of Shipping, Road Transport & Highways through a gazette notification. In addition 60-km 'missing link' between NH-57 and NH-37 connecting Dibang and Lohit valley in the state has also been declared as an extension of the NH-37. It will now be implemented by the ministry under the Special Accelerated Road Development Programme (SARDP) for the North-East.
The ₹10,000 crore project to provide a two-laned connectivity right through Arunachal Pradesh will stretch out between the strategic Tawang area to Mahadevpur ending near Dibrugarh in Assam. NH 52B will include 220 km of the existing NH 52 stretch, and will also touch Bomdila, Nechipur, Seppa, Sagalee, Ziro, Daporijo, Along, Pasighat, Roing Teju, Mahadevpur, Namchik, Changlang and Khonsa on the Nagaland border and Kanubari en route.
