World Bank lends $110 million to rebuild Sri Lanka roads after cyclone

What happened

The money comes from the Crisis Response Window of the International Development Association (IDA), the part of the World Bank that lends to lower-income countries on easy terms. It is added to an existing loan programme called the Inclusive Connectivity and Development Project, which is extended by three years. With this addition, World Bank support for Sri Lanka's transport connectivity under that project reaches 610 million US dollars.

The roads chosen first are those that restore access to markets, schools and health facilities in the communities hit hardest. The World Bank says the project will directly benefit more than 830,000 people and reach close to 2 million across eight target districts. It expects about 5,671 new or improved jobs in reconstruction and maintenance, and says close to 22,000 tea, vegetable and paddy farmers will be reconnected to buyers.

Gevorg Sargsyan, the World Bank's country manager for Sri Lanka, said the cyclone had badly damaged the country's connections, and that rebuilding was a chance to build back stronger. The project fits within the World Bank Group's partnership framework for Sri Lanka for 2026 to 2030. The 600 km covered by this loan is a small share of the damaged network, so other funding will be needed for the rest of the roads and bridges.

Cyclone Ditwah was not a strong storm by wind speed, but it brought extreme rainfall. The World Bank estimates total damage at 4.1 billion US dollars, with nearly 2 million people affected across all 25 districts. Transport damage alone is estimated at about 973 million dollars. That figure includes close to 2,000 km of provincial roads, more than 3,500 km of rural roads and close to 700 bridges. The cost of transport recovery is put at 1.31 billion dollars.

The engineering behind it

Landslides caused much of the harm. Writing for Eos in December 2025, the landslide scientist Dave Petley cited a United Nations Development Programme (UNDP) report of about 1,200 landslides, with around a fifth of the island affected by flooding. He reported 639 known deaths and 203 people missing at the time. Many deaths happened in debris flows, where shallow landslides reached stream channels and turned into fast-moving flows of mud and rock. The worst loss of life was in Kandy district, in the hilly centre.

Water is the main enemy of a road. When rain cannot drain away quickly, it soaks into the pavement layers and the ground below, which weakens them. On hill roads, water flowing over or through a slope adds weight and reduces the strength of the soil, which can trigger a slope failure. Most road damage in heavy rain comes from poor drainage rather than from the road surface itself. This is general engineering knowledge, not a finding from this project.

Improved drainage usually means several connected parts. Side drains collect water from the road surface. Culverts carry streams and drain water under the road, and they must be large enough for heavy storms, not only average ones. Catch drains above a cut slope stop water from running down its face. Outlets must be protected so that the released water does not wash away the slope below the road.

Landslide protection covers a range of methods. Engineers may reshape a slope to a safer angle, build retaining walls or gabion walls at its foot, install horizontal drains to lower the water inside it, or plant vegetation to bind the surface. Choosing among them depends on the type of soil or rock, the slope height and the cost. A good design starts with site investigation and a study of how the slope failed before.

What it means in Nepal

The sources for this story are about Sri Lanka, so this section is about the kind of work and the skills rather than about Nepal's roads. The most important point is that lenders now attach design standards to reconstruction money. In this project, the World Bank requires climate-resilient standards, including drainage, landslide protection and engineering for extreme weather. Engineers who can design to such standards, and show that a design meets them, are part of every project of this kind.

A second point is that a resilient road costs more to build than a simple repair. The engineer must justify the extra cost by comparing it with the cost of repeated damage, closures and lost access. That needs a cost estimate, an understanding of rainfall and flood frequency, and the ability to explain choices to a lender or government. Hydrology, geotechnical engineering and estimating all meet in this one task.

A third point is that much of the work after a disaster is maintenance, not new construction. The World Bank counts jobs in both reconstruction and maintenance. Clearing drains before the rainy season, repairing small slips early and checking culverts after storms are simple tasks, but they decide whether a road survives the next heavy rain. Engineers who plan and supervise this routine work, and keep good records of where failures happen, help a road network last.
