Highway system

The Trans-Arunachal Highway (TAH), which includes an existing 1,811 km (1,125 mi) route comprising NH-13 (1,559 km (969 mi)) and parts of NH-15 (80 km (50 mi)), NH-215 (30 km (19 mi)) and SH-25, is an under-construction 2-lane more than 2,407 km (1,496 mi) long highway passing through 16 districts in Arunachal Pradesh state in India. It runs from LAC in Tawang in northwest to Kanubari in southeast at tri-junction of Assam-Nagaland-Arunachal Pradesh. It connects at least 16 districts of Arunachal Pradesh.[1][2][3][4][5][6]

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.[1][7]

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.[1] 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.[8] 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.[9] TAH, from Tawang to Kanubari in Longding district has a target completion date of March 2024.[10]

History

In January 2008, the project was announced by then Prime Minister of India, Manmohan Singh.[10]

Construction agencies

Following follow agencies are responsible for the construction of TAH in several packages.

Project details

Route: existing

Future extensions

Following extensions are needed to optimise the connectivity with the neighboring states and beyond, as these extensions will enable the larger national strategic objectives including eliminating the vulnerability of Siliguri Corridor.

Six Inter-corridor highways

To providing missing interconnectivity between three horizontal national highways across Arunachal Pradesh - Frontier Highway, Trans-Arunachal Highway and East-West Industrial Corridor Highway - following six vertical and diagonal national highway corridors of total 2178 km length will be built, which will also provide faster access to geostrategically important areas on India-China LAC.[13][14]
