Transportation in and out of Itanagar has historically been challenging due to the terrain, but infrastructure has vastly improved in recent years.
* **Air:** The Donyi Polo Airport (located in Hollongi, about 15 km south of the city center) was inaugurated in 2022, providing the city with its first commercial flight connections to major Indian cities like Delhi and Kolkata. Previously, the city relied on a Pawan Hans helicopter service connecting to Guwahati. * **Rail:** The Naharlagun Railway Station (about 15 km from Itanagar proper) connects the capital to the Indian railway network, offering direct trains to Guwahati, Delhi, and other major hubs. * **Road:** National Highway 415 (NH 415) is the primary arterial road running through the capital complex, connecting Itanagar to Banderdewa on the Assam border. * **Local Transit:** Public transport relies heavily on shared local taxis (Sumos and auto-rickshaws) and state transport buses. Walking can be strenuous due to the steep inclines.
