The Société Nationale des Transports Nigériens (SNTN) was created in 1963 as a continuation of the Niger branch of the colonial Transafricaine company. It was 47% owned by the SAGA Group (branch of Rotschild) from France and 53% by the Niger government. It operated interurban buses and goods transport. In 1977 it took over the SNTU (Société Nationale des Transports Urbains), which operated the urban services in Niamey. In 1996, because of continuing difficulties, the urban services in Niamey were transfered to Société des Transports Urbains de Niamey (SOTRUNI) and the interurban services to Société Nigerienne de Transports de Voyageurs (SNTV). SNTN continued goods transport for "strategic and dangerous" goods. SNTN still has some passenger services in remote areas, though in January 2015 no buses were seen and all trucks were wrecks.
