Arunachal Frontier Highway, officially notified as theNational Highway-913 and also called Bomdila-Vijaynagar Highway, connectingBomdila in northwest toVijaynagar in southeast including 800 km greenfield section and network of new tunnels & bridges, is mostlylntermediate-lane (5.5 m or 18 ft) and in some sections 2-lane paved-shoulder under-construction national highway along theIndia-Tibet border in the Indian state ofArunachal Pradesh. The 1,748 km-long (1,086 mi) highway itself will cost₹27,000crore (equivalent to₹290 billion or US$3.4 billion in 2023) and total cost including 6 additional inter-corridors is₹40,000crore (equivalent to₹420 billion or US$5.0 billion in 2023).
In some places, this highway will run as close as 20 km from the LAC. To be constructed byMoRTH in 9 packages, all packages will be approved by the end of FY 2024-25 (March 2025) and construction will be completed in 2 years by 31 March 2027.[1][2][3][4][5][6] Of the total route, 800km is greenfield, rest brownfield will be upgraded and tunnels will be built.[7] This highway in the north & east Arunachal along the China border would complement theTrans-Arunachal Highway (through the middle of Arunachal) and theArunachal East-West Corridor (in south Arunachal in foothills along the Assam border) as major highways spanning the whole state, pursuing theLook East connectivity policy.[8][9]
In 2016,empowered committee on border infrastructure asked the MoRTH to prepare the detailed project reports (DPR) as per the alignment agreed by the home ministry, defence ministry & Arunachal state government. In 2018, Home ministry enhanced the alignment for the additional connectivity.[1][2] MoRTH identifies the highway as one of the 29 corridors close to the 3,600 km international border, to be undertaken as aNHDP (which has been subsumed by theBharatmala project), though there is "little habitation" along the proposed route and only "small stretches of minor roads".[4]
It will be constructed in the following nine packages,[10] all approvals and land acquisition will be progressively completed by March 2025, and the construction will be progressively completed by March 2027[1][2] in fully government-funded "engineering procure and construct" (EPC) mode.[11]
Package-1 Nafra–Lada, 141 km (Nafra–Dibrick–Sachung–Lada):[10] full budget approved in 2023.
Package-2 Lada–Sarli, 200 km:[10] for 106 km budget of ₹ 2,249 crore approved in Feb 2024.[11]
Package-3 Sarli-Tali, 201 km (Sarli-Huri–Parsi Parlo–Tali):[10]
Sarli-Huri: for 35 km a budget of ₹626.92 crore approved in Feb 2024.[11]
Package-4 Tali–Mechuka, 225 km (Tali–Taliha–Siyum–Mechuka):[10]
Package-5 Mechuka–Bile, 183 km (Mechuka–Tato–Monigong–Tato–Bile):[10]
Package-6 Bile–Hunli, 230 km (Bile–Migging–Tuting–Singa–Anelye–Hunli):[10]
Highway will generate employment and increase tourism in these hard-to-reach areas.
Highway will check Chinese incursions into Indian territory. China has built an extensive road and railway network on its side, posing a security risk to India as the region is relatively inaccessible on the Indian side.
India'sNational Board for Wildlife approved diversion of 310 hectares ofNamdapha National Park - habitat fortigers (India is home to 76% of world's tiger population),clouded leopards, andred pandas (only panda species in India) - forest land for this highway for boosting state's remotest habitation's socio-economic development. The wildlife protection is a major consideration for the project, and to ensure the wildlife movement corridors are not disrupted by the highway the wildlife passage culverts and underpasses customised to the site-specific data-backed research have been constructed.[14] The highway will also cross theDibang Wildlife Sanctuary.
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.[16][17]

Tawang-Yongphulla Highway spur, proposed as a 100 km long western spur fromTawang toYongphulla Airport in Bhutan (upgraded by India and jointly used by the Indian Army and Bhutan Army)[18] in eastern Bhutan viaLumla-Yabab in India andTrashigang in Bhutan.
Miao-Kharsang Highway spur is likely awaiting approval as the National Highway, though state-level lower-status connectivity plan may exist (Nov 2025 update).
Under theVibrant Villages Programme, feeder roads to 122 border villages in Arunachal, at the cost of ₹2,205 crore, are being constructed which will connect to the Arunachal Frontier Highway. This budget also includes community centers and public infrastructure in those villages along the India-Tibet border to empower the villagers.[14]

MoRTH announced that all approvals and land acquisition will be progressively completed by March 2025, and the construction will be progressively completed by March 2027 in the overlapping phases.[1][2]
2023 May: All the DPR (detailed project reports) for the main route and the six inter-corridors, various approvals including environmental and forest, and land acquisition will be completed by March 2025, and construction will be completed in 2 years by March 2027.[21]
