With an underdeveloped railway network, principally due to its difficult terrain, the road system is of vital importance for the development of the country.
The total length of the Armenian road network is 8,140 km (5,060 mi), 96.7% of which is asphalted.
Armenia is a member of the International Road Transport Union and the TIR Convention.
The first roads as we conceive them in a modern perception, appeared in Armenia in the 19th century.
The letter by which these roads are numbered is "T", "Տ" in Armenian, standing for Տեղական, meaning Local.
