This publication provides an overview of low-cost rural tunnels in the context of developing countries in Asia and the Pacific. It explains benefits, methodologies, and costs, and how they contribute to the ADB Strategy 2030.

In rural areas, tunnels for transport, irrigation, and other purposes can provide a cost-effective, low-maintenance, and safe alternative to surface routes in difficult terrain. They also have a smaller environmental footprint by reducing emissions and lessening impacts on biodiversity and cultural heritage. Well-designed and constructed tunnels are resilient and provide rural communities with an important asset for generations, if not longer.
