Construction of the Päädeva–Orgita and Haimre traffic interchange as a 2+2 lane highway

In early November, the Estonian Transport Administration and Tariston AS signed an agreement, according to which the Tallinn–Pärnu–Ikla state road km 62.2–64.8 Päädeva–Orgita and km 68.2–70.2 Haimre traffic interchange will be converted into a 2+2 lane highway.

The expected start of the works is in early 2026 and the completion date is in autumn 2027. At the current construction stage, road and infrastructure work designs for selected sections are being prepared and the necessary approvals and permits are being applied for.

A traffic study shows that traffic volume has increased 2 times in 20 years, the traffic of road trains 2.4 times, and in the future the traffic volume on the section is expected to exceed 12,000 vehicles per day, a large part of which are heavy goods vehicles.

The construction works are partly co-financed by the Connecting Europe Facility (CEF) through the military mobility measure.

Overview of planned works

During the construction works, nearly five kilometers of new 2+2-lane highway will be built on the Päädeva–Orgita section and at the Haimre traffic interchange. The intersection of Pärnu Highway and Rapla Highway (T28) will also be renovated and rebuilt into a roundabout. In the future, traffic between Märjamaa and Rapla will run over the Orgita viaduct, which is located at kilometer 63.47 of the Pärnu Highway, slightly earlier than the current Rapla Highway intersection. A pedestrian tunnel will be built at the current intersection of Märjamaa and Pärnu Highway.

In addition, demolition works will take place on the Linnametsa property near kilometer 64.7 of the T4 construction route, where old buildings and structures will be removed. Two wildlife crossings and one livestock tunnel will also be built on the section to ensure the safe movement of animals across the highway.

The Haimre traffic interchange will be completely rebuilt. From now on, traffic in the Haimre–Märjamaa direction will run over the new Haimre viaduct, and passengers will be directed to Pärnu Highway via connecting roads. Although the construction will take place in a nature reserve, all work will be carried out strictly within the designated boundaries.

Traffic management

During the construction works, this section has been marked with temporary traffic management and, depending on the work stages, traffic diversions may occur. One lane will remain open to road users in both directions throughout the construction period. Major changes to traffic management are planned for the second half of 2026.

Although the construction load on the Tallinn–Pärnu route in the coming years will be very high, it will help to reach modern and convenient connections more quickly. The four-lane road section that will be completed will provide safer traffic on a road with high traffic volume and will also support security, as the infrastructure being built will take into account the needs of military transport.

Environmental protection and animal safety

To improve safety on the 2+2 road section, wildlife fences will be built on both sides of the road to prevent animals from entering the road and to ensure road safety. As environmental impact mitigation measures, animal jump-out points will be provided at the ends of the wildlife fence and in the area of ​​the break. 2 wildlife crossings and 1 livestock tunnel will be built for the passage of small wildlife.
