located 12 km northwest of Agartala at Singerbhil, is the second busiest airport in northeast India after Guwahati. There are direct flights to Kolkata, Imphal, Delhi, Shillong, Guwahati, Bangalore, Chennai, Ahmedabad and Mumbai. The major airlines are AirAsia India, Air India and Indigo Airlines.[85] Passenger helicopter services are available between the capital and major towns (Kailashahar, Dharmanagar) as well as to more remote areas such as Kanchanpur, Belonia and Gandacherra.
Agartala, came on India's railway map with the advent of the railways in the subcontinent in 1853 but the link was broken when India was partitioned in 1947. Railway service was established in Tripura in 1964 by constructing 1,000 mm (3 ft 3+3⁄8 in) metre gauge track from Lumding in Assam to Dharmanagar and Kailasahar in Tripura but the track did not connect the state capital Agartala. Rail transport was absent in the state until 2008–09 when the railway track was extended to the capital Agartala.[86] The metre gauge rail track was connected to 5 ft 6 in (1,676 mm) broad gauge at Lumding. The major railway stations in this line are in Agartala, Dharmanagar, and Kumarghat. This metre gauge track was converted to 1,676 mm (5 ft 6 in) broad gauge in 2016 and now trains run from Agartala to Kolkata and Delhi. The total length of this railway track in Tripura state is 153 km. It is a single line without electrification.
The 76 km long track from Agartala to Belonia railway station (station code BENA) has been commissioned and two trains run on this section. The 38 km long section from Belonia to Sabroom on the bank of Feni River, which separates Tripura from Bangladesh, is being constructed as of 2019.
A new railway line is being laid westwards from Agartala to Akhaura in Bangladesh. This will reduce the distance between Agartala and Calcutta by over 1000 km and provide rail access to Chittagong port.
Only one major road, the National Highway 8 (NH-8), connects Tripura to the rest of India.[86] Starting at Sabroom in southern Tripura, it heads north to the capital Agartala, turns east and then north-east to enter the state of Assam. Locally known as "Assam Road", the NH-8 is often called the lifeline of Tripura.[86] However, the highway is single lane and of poor quality; often landslides, rains or other disruptions on the highway cut the state off from its neighbours.[33]: 73 [74]: 8 Another National Highway, NH 108, connects the town Panisagar in North Tripura District with Aizawl, Mizoram.[32] The Tripura Road Transport Corporation is the government agency overlooking public transport on road. A hilly and land-locked state, Tripura is dependent mostly on roads for transport.[86] The total length of roads in the state is 16,931 km (10,520 mi) of which national highways constitute 88 km (55 mi) and state highways 689 km (428 mi), as of 2009–10.[86] Residents in rural areas frequently use waterways as a mode of transport.[87]: 140
Tripura has an 856 km (532 mi) long international border with Bangladesh, of which 777.4 km (483.1 mi) is fenced, as of 2012.[88] Several locations along the border serve as bilateral trading points between India and Bangladesh, such as Akhaura near Agartala, Raghna, Srimantpur, Belonia, Khowai and Kailasahar.[80] A bus service exists between Agartala and Dhaka, the capital of Bangladesh.[89][90] In 2013, the two countries signed an agreement to establish a 15 km (9.3 mi) railway link between Agartala and the Akhaura junction of Bangladesh.[91] Citizens of both countries need visa to legally enter the other country; however, illegal movement and smuggling across the border are widespread.
