The road is a dual carriageway for 70 kilometres. The main part is between Tallinn and Võõbu (64.2 kilometres). The remainder can be found near Mäo (5.9 kilometres) and near Tartu (1 kilometre). The dual carriageway stretch between Võõbu and Mäo is planned to be completed in 2022. The current road is a first in many road standard improvements: the first Estonian speed cameras were posted on the T2, also the first wildlife crossing in Estonia was completed in 2013.
