Definition
Route nationale 6 (RN 6) is a primary national highway in Madagascar that extends for approximately 706 km, linking the northern city of Antsiranana with the central town of Ambondromamy.
Overview
RN 6 traverses the Diana and Sofia regions, forming a crucial north‑south transport corridor. The road was fully paved in 1992; while most of its length is paved and maintained, certain sections remain unpaved and are reported to be in poor condition. The route serves both commercial traffic and tourism, providing access to several natural reserves and coastal towns.
Etymology/Origin
The designation “Route nationale” is French for “national road,” reflecting Madagascar’s historical ties to France. The numeral “6” identifies the highway within the national road numbering system.
