Georgia's trunk highways form a network of internationally oriented roads that connects the Georgian capital of Tbilisi, home to roughly a third of the national population, with neighboring countries. This is the backbone for a network of domestic trunk roads connecting vital regions with each other and the capital. The total length of the road network in Georgia is 21,100 kilometres (13,100 mi) in 2021.[1] The roads of "international importance" and "national importance" are managed by the Roads Department (Georoad) of the Ministry of Regional Development and Infrastructure of Georgia.
