Padma Bridge

The Padma Bridge (Bengali: পদ্মা সেতু, Padma Setu) is Bangladesh's largest infrastructure project, a two-tier steel-truss structure carrying a four-lane highway on its upper deck and a single-track broad-gauge railway below. Spanning the Padma River between Munshiganj (Mawa) on the north bank and Shariatpur–Madaripur (Janjira) on the south, it physically links the country's south-western 21 districts to the capital Dhaka and the eastern economic heartland. At 6.15 km it is the longest bridge over the Ganges–Padma system and one of the most technically demanding river crossings in the world, owing to the Padma's strong currents, deep scour, and shifting morphology. It was inaugurated by Prime Minister Sheikh Hasina on 25 June 2022 and opened to traffic the following day.

The project is most significant in Bangladesh's national narrative as a self-financed undertaking. The World Bank, which had committed roughly US$1.2 billion, cancelled its credit in 2012 alleging a corruption conspiracy in the procurement process — a charge later dismissed by a Canadian court in 2017 in the SNC-Lavalin matter for lack of evidence. The government of Bangladesh subsequently funded the entire estimated cost of about Tk 30,193 crore (roughly US$3.6 billion) from its own budget, making the bridge a symbol of national sovereignty and economic confidence. Engineering was executed by China Major Bridge Engineering Company, with construction supervision by Korea Expressway Corporation; the river-training works were carried out by Sinohydro. The bridge rests on 42 piers founded on driven steel tubular piles reaching depths exceeding 120 metres — among the deepest bridge foundations attempted anywhere.

Economically, the bridge is projected to add roughly 1.2 percent to national GDP and around 2 percent to regional GDP, integrating the previously ferry-dependent south-west — including the Mongla and Payra ports, the Khulna industrial belt, and the Benapole land border with India — into the national supply chain. The associated railway link to Jashore opened in stages, with the broad-gauge line through the bridge commissioned in 2023, shortening the Dhaka–Khulna corridor and forming part of the Trans-Asian Railway Network. The bridge has eliminated the chronic delays and seasonal closures of the Mawa–Janjira ferry crossing, transforming travel time from hours to minutes and catalysing investment along the corridor. By 2026 it stands as a completed, fully operational flagship of the government's connectivity agenda alongside the Karnaphuli Tunnel and metro rail.

For the BCS examination, the Padma Bridge is a recurrent topic in Bangladesh Affairs, tested both as factual recall — length, location, inauguration date, financing model, contractors — and as an analytical theme on self-reliant development, mega-project governance, and the World Bank controversy. Candidates should be ready to cite the 2012 funding cancellation and its 2017 judicial vindication, distinguish the road and rail components, and connect the bridge to regional connectivity initiatives, Vision 2041, and the SDG infrastructure goals. Questions frequently pair it with other landmark projects to test comparative awareness of Bangladesh's development trajectory.
