Transport and Logistics of Assam: Roads, Rail and NW-2
Transport is the lifeline of Assam's economy. Surrounded by hills and dependent on long supply lines, the state relies on roads, railways, airways and, above all, its rivers to move people and goods. The Brahmaputra, designated as National Waterway-2, is one of the most important inland waterways of India, and a series of bridges, highways, airports and multimodal hubs are reshaping connectivity. This chapter covers the road network, the railway system under the Northeast Frontier Railway, the national waterways and river ports, the airports and the major bridges and logistics projects that are repeatedly asked in ADRE, APSC and similar examinations.
Road network
National Highway 27 (earlier known as NH-31 and part of NH-37) forms the East-West Corridor passing through Assam and is the longest national highway in the state. The National Highways Authority of India (NHAI) and the Public Works Department (NH wing) construct and maintain national highways, while state highways and major district roads connect the district headquarters. The Guwahati-Shillong road was upgraded to a four-lane highway. Although the road density of Assam is below the national average, the plains have a fairly good network. Road connectivity to neighbouring states and to the international borders with Bhutan and Bangladesh is expanding under various central and state projects.
Railways
The railway network of Assam is covered by the Northeast Frontier Railway (NFR), whose headquarters is at Maligaon in Guwahati. Most railway lines in the state are broad gauge (1676 mm), converted under Project Unigauge. Guwahati Railway Station is the largest railway station of Assam. The Bogibeel Bridge near Dibrugarh, about 4.94 km long, is the longest rail-cum-road bridge in India and connects the north and south banks of the Brahmaputra. The Saraighat Bridge over the Brahmaputra connects Guwahati with North Guwahati and was commissioned in 1962. The Kolia Bhomora Setu at Tezpur is another important bridge across the Brahmaputra. Connectivity projects such as the Agartala-Akhaura rail link and proposed links to Jogighopa are meant to strengthen trade with Bangladesh.
National Waterway-2 and river transport
National Waterway-2 (NW-2) is the Brahmaputra river, covering about 891 km from Dhubri in the west to Sadiya in the east. It is maintained by the Inland Waterways Authority of India (IWAI). Pandu port near Guwahati is a major river port on the Brahmaputra, and Dhubri and Karimganj are connected to Bangladesh ports through inland waterways under the India-Bangladesh protocol routes. The Barak river in the Barak valley is designated as National Waterway-16. The Jal Marg Vikas Project and related initiatives promote inland waterway transport. The Jogighopa Multimodal Logistics Park, being developed on the Brahmaputra and NW-2, is set to act as a dry port for transit trade with Bangladesh. Luxury river cruises such as MV Mahabaahu also operate on the Brahmaputra.
Airports and air connectivity
The Lokpriya Gopinath Bordoloi International Airport at Borjhar, Guwahati, is the principal airport of Assam and handles international flights. The Kumbhirgram Air Force Station near Silchar serves the Barak valley, while the Mohanbari Airport at Dibrugarh serves Upper Assam. The UDAN (Ude Desh ka Aam Naagrik) scheme under the Regional Connectivity Scheme connects remote areas of the state by air. Air cargo facilities at Guwahati support trade and the movement of perishable goods.
