Highways in Estonia

While there is no official prefix for road numbers in Estonia, T (tee) is used widely unofficially.

[2] The technical classification of highways is as follows:[3] The backbone of the Estonian national route system, national main routes (põhimaanteed) make up a network of 1,602 kilometres of road, amounting to 10% of the total road network.

This number will enlarge significantly with further upgrades of the T11 and the T2 between Kose and Mäo to I class highway.

There are a total of 1785 secondary roads in the registry, the shortest of them 70 metres and the longest 76,8 kilometres long.

The county codes used in the numbering system are as follows: 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.
