Guwahati: The roads being built across Northeast India are no longer merely infrastructure projects but part of an ambitious attempt to transform a region long defined by remoteness and difficult terrain into India’s economic gateway to Southeast Asia, according to a new study.
The knowledge paper, Roads & Highways in Northeast India, released during the North East India Infrastructure Summit and Exhibition 2026 in Shillong, says the region has the potential to shift from a “geographically isolated frontier to an economically integrated gateway” linking India with Bangladesh, Bhutan, Myanmar and the wider ASEAN region by 2047.
The report notes that the Northeast, despite sharing more than 5,400 kilometres of international borders with five countries, remains heavily dependent on the narrow Siliguri Corridor for connectivity with the rest of India, making it strategically vulnerable.
The study traces the region’s connectivity woes to history. Under British rule, roads and transport networks were designed primarily to extract tea, oil and timber and transport them to ports in present-day Bangladesh rather than improve connectivity within the Northeast itself. Partition in 1947 abruptly severed these networks, leaving the region with weak internal links that continue to affect development decades later.
“Roads and highways serve as the primary backbone of this transformation,” the report says, adding that highways remain the region’s lifeline despite expanding rail and waterway networks.
The report identifies the Northeast as one of the most difficult places in the world to build infrastructure. Much of Arunachal Pradesh, Nagaland, Mizoram, Manipur and Sikkim is mountainous and requires extensive tunnelling, slope stabilisation and bridge construction. Assam and Meghalaya receive some of the world’s highest annual rainfall, while the entire region lies in one of the world’s most active seismic zones, making infrastructure projects significantly more expensive and technically challenging.
Despite massive investments under Bharatmala Pariyojana, PM Gati Shakti, SARDP-NE, NHIDCL and Border Roads Organisation projects, the study says three structural challenges continue to hinder the region’s transformation: climate-vulnerable infrastructure, underdeveloped border trade facilities and fragmented integration between roads, railways, waterways, airports and logistics hubs.
The report paints a picture of a “polycentric Northeast”, where each state plays a distinct role in India’s connectivity ambitions.
Assam is described as the logistical and economic core of the region and the principal transit hub for the other seven states. Meghalaya, strategically located between Assam and Bangladesh, is identified as a potential cross-border trade and mineral transportation node, although high rainfall remains a major infrastructure challenge.
Tripura, almost surrounded by Bangladesh, is highlighted for its “exceptional cross-border logistics potential”, with Chittagong Port located just 80 kilometres away via the Maitri Setu bridge. Manipur is projected as a key pillar of the Act East Policy through the India-Myanmar-Thailand Trilateral Highway, while Mizoram’s strategic significance is expected to rise further with the Kaladan Multi-Modal Transit Transport Project.
The report also argues that roads in the Northeast serve functions far beyond transportation. Highways connect remote villages to healthcare, education and financial services, link farmers to markets, support tourism and defence logistics, and facilitate interstate commerce.
To unlock the region’s potential, the study proposes a ten-point roadmap that includes developing all-weather strategic corridors, strengthening border trade infrastructure, building logistics and warehousing ecosystems, creating dedicated tourism highways, and deepening integration with ASEAN connectivity frameworks.
Union Road Transport and Highways Minister Nitin Gadkari, in the foreword to the report, said the Northeast is poised to become one of the defining pillars of India’s development journey and that roads should be viewed as catalysts for economic transformation rather than mere physical infrastructure.
The report concludes that with sustained investment, climate-resilient infrastructure and better policy coordination, the Northeast could emerge as one of India’s most important growth engines by 2047—connected, prosperous and globally integrated.
