Luige in Harju County is the site of the junction between the Tallinn Ring Road and the Tallinn–Rapla–Türi highway. Heavy traffic (nearly 8,500 cars per day in 2010) used to cause traffic jams at the old traffic light regulated intersection during peak hours. AS K-Projekt, who developed the technical design for the Luige junction, and OÜ Järelpinge Inseneribüroo were commissioned to plan the construction of a multi-level junction in order to make traffic flows smoother and safer. On 7 September 2011, the Road Administration entered into an agreement with the public limited companies Nordecon and Järva Teed for the reconstruction of the junction. Two roundabouts were built on the Tallinn–Rapla–Türi highway and traffic on the Tallinn Ring Road was diverted over the viaduct. The section of the Tallinn Ring Road in this area was converted into a modern four-lane (2 + 2) highway with a central reservation. In addition, the project included the construction of a network of branch roads and shared-use paths in the area, including a viaduct for pedestrians and cyclists across the Tallinn Ring Road. A 1,650-metre-long, three-metre-high noise barrier was built, as well as 1,850 metres of wildlife barrier fencing. The project was completed early, and the first cars crossed the viaduct of the Tallinn–Rapla–Türi highway at 11 in the morning on 4 January 2012.
