Maitri Setu Bridge

The Maitri Setu ("Friendship Bridge") is a 1.9-kilometre road bridge spanning the Feni River, the natural boundary that separates the southern tip of India's Tripura state from the Chittagong Division of Bangladesh. It connects Sabroom in Tripura's South District with Ramgarh in Bangladesh's Khagrachari district. Construction was executed by the National Highways and Infrastructure Development Corporation Limited (NHIDCL), a fully owned company of India's Ministry of Road Transport and Highways, at a cost of roughly ₹133 crore drawn from Indian funds. The project was conceived as part of India's "Act East" policy and the broader sub-regional connectivity architecture that has developed under the Bangladesh–Bhutan–India–Nepal (BBIN) framework. The bridge was jointly inaugurated on 9 March 2021 by Prime Minister Narendra Modi and Prime Minister Sheikh Hasina through a video conference, an event that also launched a clutch of allied connectivity and development projects.

The strategic logic of the bridge rests on geography. Sabroom lies only about 72 kilometres from the deep-sea Chittagong Port (Chattogram), Bangladesh's principal maritime gateway, whereas India's own ports are separated from the landlocked Northeast by the narrow Siliguri Corridor — the so-called "Chicken's Neck" — and distances exceeding 1,600 kilometres. The Maitri Setu therefore creates a short overland route by which goods originating in or destined for Tripura, Mizoram, southern Assam and beyond can reach international shipping lanes via Bangladeshi territory. To operationalise this corridor, the Indian side developed an Integrated Check Post (ICP) at Sabroom to handle customs, immigration, and cargo clearance, while the bridge's approach roads were tied into National Highway 8. The mechanics are thus threefold: the physical span across the Feni, the border-management infrastructure at Sabroom, and the transit arrangements negotiated with Dhaka that permit movement of goods to and from Chittagong and Mongla ports.

The transit dimension is embedded in a wider legal and institutional scaffolding. The use of Chittagong and Mongla ports by Indian cargo is governed by the Agreement on the Use of Chattogram and Mongla Ports (ACMP), signed in October 2018 and operationalised through standard operating procedures finalised subsequently, with trial runs of transit cargo conducted from 2020 onward. The bridge also complements the Bangladesh–Bhutan–India–Nepal Motor Vehicles Agreement (BBIN MVA) of 2015, which provides for the seamless movement of passenger, personal and cargo vehicles across the four countries' territories. The Maitri Setu is, in effect, a single physical node within a layered connectivity programme that includes rail links such as the Agartala–Akhaura line, inland waterway protocols on the Gumti and other rivers, and road upgrades across the Northeast.

Contemporary developments around the bridge have been driven by ministries in both capitals. India's Ministry of External Affairs and Ministry of Road Transport and Highways, the Tripura state government in Agartala, and Bangladesh's Ministry of Shipping and Ministry of Road Transport and Bridges in Dhaka have each played roles. The bridge structure was completed in 2020, formally inaugurated in March 2021, and full commercial cross-border vehicular and trade movement awaited completion of the Sabroom ICP and the harmonisation of customs procedures. By the mid-2020s, the corridor had been positioned as a flagship illustration of the deepening India–Bangladesh partnership celebrated in joint statements during state visits, alongside power-sector cooperation and line-of-credit funded infrastructure.

It is important to distinguish the Maitri Setu from adjacent concepts. It is not the same as the Akhaura–Agartala rail link, a separate cross-border railway connecting Tripura's capital to Bangladesh's rail network that was inaugurated in November 2023; the two are complementary modes within the same connectivity push. Nor should it be conflated with the broader ACMP transit regime, which is a legal arrangement for port use rather than a physical structure — the bridge enables but does not constitute the transit. The name "Maitri" is shared with other India–Bangladesh symbols, including the Maitree Express train between Kolkata and Dhaka and the Maitree Super Thermal Power Project at Rampal, none of which are connected to the Feni River bridge.

Several edge cases and sensitivities attend the project. Cross-border connectivity through Bangladeshi territory remains politically salient in Dhaka, where transit to India has historically attracted domestic debate over sovereignty and reciprocity, making the pace of operationalisation contingent on the bilateral political climate. The Feni River itself is the subject of unresolved water-sharing discussions, and the surrounding Chittagong Hill Tracts carry their own security considerations. The change of government in Bangladesh in August 2024 introduced fresh uncertainty into several connectivity initiatives that had advanced under the Hasina administration, underlining how such infrastructure depends on sustained intergovernmental commitment rather than the physical asset alone.

For the working practitioner — the UPSC aspirant preparing General Studies Paper II, the desk officer tracking the Northeast, or the analyst assessing regional connectivity — the Maitri Setu is a compact case study in how infrastructure advances foreign-policy objectives. It demonstrates the operational meaning of "Act East," the strategic value of port access for a landlocked region, and the way bilateral connectivity reduces dependence on the vulnerable Siliguri Corridor. It also illustrates the interdependence of hard infrastructure and soft legal arrangements: a completed bridge yields little economic dividend until customs, transit agreements and approach roads are aligned. As such, it remains a frequently cited example of contemporary India–Bangladesh cooperation and South Asian sub-regionalism.
