Highways in Estonia are the main transport network in Estonia. The Estonian national classification includes several classes of highways:[1]
Other than these, the national road classification includes the following categories which may also be referred to as highways in a general sense, with decreasing order of priority (and applicability of the term highway):
Main and support routes are designated with 1-2 digit numbers. Side routes are designated with 4-5 digit numbers, where the first two digits is a county code (11-25 for 15 counties), followed usually by three (rarely two, used for leftover spurs) digits. While there is no official prefix for road numbers in Estonia, T (tee) is used widely unofficially.
In addition to state highways, there are 23 920 km of local roads and around 18 398 km of private and forest roads. The total Estonian road network is estimated to be almost 59 thousand km.[2]
