Roads in Armenia serve as the main transport network in Armenia. With an underdeveloped railway network, principally due to its difficult terrain, the road system is of vital importance for the development of the country. Its role is important in both national and international traffic.
The total length of the Armenian road network is 8,140 km (5,060 mi), 96.7% of which is asphalted. For every 1,000 km2 (390 sq mi) of national territory, there are 258 km (160 mi) of roads. Armenia is a member of the International Road Transport Union and the TIR Convention.
