Highways in Estonia

Under earlier legislation, roads were classified according to traffic density into seven classes - "motorway" and classes I-VI to establish design standards (such as cross-section width). This classification was abolished in 2023.^[2]

Map of the Estonian main roads network (põhimaanteed)

The backbone of the Estonian national route system, national main routes (põhimaanteed) make up a network of 1603 kilometres of road, amounting to 10% of the total national road network. The traffic numbers however make up nearly 50% of the Estonian road network's traffic volumes. The highest AADT's are around Tallinn, on the T1 between Loo and Maardu, on the T2 between Tallinn and Jüri, and on the T4 between Laagri and Kanama (the highest AADT on Estonian national routes at 31,000). A main route is defined as a highway that connects the capital with other large cities or connects large cities and the capital with major ports, railway points and border crossings. Currently there are 12 separate main routes, which are marked with 1–2 white digits on a red shield. The speed limits on Estonian main routes are 110 or 120 on 2+2 sections and 90 on regular roads (on newer sections of road, these are adjusted according to conditions by electronic speed limit signs).

The main routes are the only roads with I class highways. The total amount is 234.6 kilometres, found on the T1, T2, T4 and T11. This number will enlarge significantly with further upgrades of the T4 in several sections between Ääsmäe and Pärnu, T2 Between Mäo and Tartu to I class highway. There are currently no motorways in Estonia, however 45,3 kilometres of the T2 is restricted-access I class highway. Ten main routes are a part of TEN-T, six routes are a part of the International E-road network. The routes E263, E67, E20, E264 and E265 run through Estonia.

The highways are maintained by the Estonian Road Administration outside city limits. Inside cities and towns, the roads are maintained by the city government.

Map of the Estonian basic roads network (tugimaanteed)

Support routes (tugimaanteed) are the second highest classification in the Estonian national route system. They make up a network of 2,405 kilometres of road, amounting to 15% of the total road network. A support route is defined as a highway, that connects towns with other towns and main routes. Currently there are 77 separate support routes. The support routes are marked with 2 black digits on a yellow shield.

Map of the Estonian E-roads network

Estonia is a part of the UNECE, and therefore also has numerous E-roads running through it. The E-roads in Estonia form a network on top of the main routes and are usually signposted on all signs. They make up a network of 994 kilometres (618 miles) of road. Currently there are six separate European routes in Estonia.
