$145 M Infrastructure Project to Transform Transport and Connectivity in Tonga

Beyond resilience, the project is expected to deliver substantial economic benefits by improving efficiency across Tonga’s transport network.

Thousands of Tongans are set to benefit from safer, more reliable access to jobs, markets, and essential services as a major $145 million infrastructure initiative gets underway on Tongatapu, marking one of the Pacific nation's most significant investments in climate resilience and urban connectivity.

The Tonga Sustainable Economic Corridors and Urban Resilience Project, backed by a powerful coalition of global and regional partners, aims to future-proof critical transport infrastructure against extreme weather while unlocking economic opportunities across the island.

The project is financed through a combined package of US$145 million, including US$40 million in grant funding from the World Bank's International Development Association (IDA), US$80 million from the Asian Development Bank (ADB), and US$25 million from the Government of Tonga — reflecting a coordinated push to strengthen resilience in one of the world's most climate-vulnerable regions.

Building Resilience Against Climate Threats

At its core, the project addresses a pressing challenge: Tonga's infrastructure is increasingly exposed to flooding, cyclones, and rising sea levels, which regularly disrupt transport links and economic activity.

The initiative will finance the construction of a new climate-resilient bridge, alongside extensive upgrades to key road networks. These improvements are designed to maintain connectivity even during extreme weather events — a critical factor for emergency response, evacuation, and continuity of essential services.

In addition, the project includes modern drainage and water management systems to reduce flooding in urban areas, tackling one of the most persistent causes of disruption for communities and businesses.

Together, these investments aim to ensure that transport corridors remain operational during crises, protecting livelihoods and reducing long-term economic losses.

Unlocking Economic Growth and Connectivity

Beyond resilience, the project is expected to deliver substantial economic benefits by improving efficiency across Tonga's transport network. A key feature is the creation of a more direct and reliable link between the island's airport and port, streamlining the movement of goods and people.

Improved connectivity is expected to:

• Reduce travel times for workers and businesses

• Enhance access to markets for local producers

• Support tourism and trade by improving logistics

• Enable faster emergency response and evacuation during disasters

"This investment will strengthen critical infrastructure while enhancing safety and connectivity for our people," said Tonga's Prime Minister, Lord Fatafehi Fakafānua. "It will help ensure that individuals can get to work in less time, communities are better connected, and families can move safely — including during natural disasters."

A New Model for Faster, More Efficient Delivery

A standout feature of the project is its innovative delivery model, which brings the World Bank and the Asian Development Bank together under a unified framework — a departure from traditional approaches where institutions operate separately.

Under this model:

• A single set of rules and procedures governs the project

• The Asian Development Bank leads preparation and implementation

• The World Bank provides financing alongside ADB

This streamlined approach is designed to reduce duplication, accelerate decision-making, and ensure that funding translates into tangible results more quickly.

"This is about keeping people moving and connected to opportunity," said Stephen Ndegwa, World Bank Division Director for the South and North Pacific. "By working in close partnership, we are helping Tonga invest in infrastructure that supports jobs during construction and drives long-term business growth."

Development experts say this collaborative model could serve as a blueprint for future projects in small island developing states, where capacity constraints and urgent climate risks demand faster, more coordinated action.

Supporting Jobs and Long-Term Development

The project is expected to generate employment during its construction phase, providing a short-term economic boost while building infrastructure that supports sustained growth.

Once completed, improved transport systems are likely to attract further investment, enhance productivity, and strengthen Tonga's resilience to external shocks — from climate events to global economic disruptions.

A Strategic Investment in Tonga's Future

As climate change intensifies across the Pacific, investments like the Tonga Sustainable Economic Corridors and Urban Resilience Project are becoming increasingly critical. By combining infrastructure development with climate adaptation, the initiative reflects a broader shift toward building economies that are not only more connected, but also more resilient.

With construction set to move forward under a coordinated international partnership, the project represents a decisive step toward securing Tonga's infrastructure, economy, and communities for the future.
