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. See the following, listed west to east: • Thelamara-Tawang-Nelia inter-corridor, 402 km. • Itakhola-Seppa-Parsi Parlo inter-corridor, 391 km. • Gogamukh-Taliha-Tato inter-corridor, 285 km. • Akajan-Jorging-Pango inter-corridor, 398 km. • Pasighat-Bishing inter-corridor. • Kanubari-Longding inter-corridor, 404 km. ==Tourism ==
