Stone Arch Bridges in Tanzania

Rural communities' access to schools, hospitals, markets and jobs depends on dangerous river crossings. Safe year-round crossing on a stone arch bridge is therefore a foundation for sustainable development.


Population growth and dispersion in Tanzania puts a major strain on mobility infrastructure. Unfortunately, the national government struggles to cope with the rapidly increasing demand. Much needed infrastructure projects using conventional techniques, such as steel and reinforced concrete, are often very expensive.

The tried and tested technology of stone arch bridges allows for a decentralised approach embedded within local government structures. This cost-effective method with high local ownership guarantees a long-lasting upgrade of rural roads.
