Road construction will take place on Ringtee Street on the section between Raja Street and Variku railroad viaduct and from the intersection at Riia 140 to the city border. Construction will also take place on Aardla Street between Riia mnt and Savi Street, as well as on the Riia-Varblase section.
The Riia intersection will become grade separated. The head-on route Tallinna-Tartu-Võru-Luhamaa will be directed over the turbo roundabout with a viaduct, and the turbo roundabout shall include two traversing lanes in both directions. To relieve rush hour traffic, two traversing lanes shall be made available for turning left when coming from Võru and heading to Valga, and when coming from Tallinn and heading to Tartu city centre.
Grade separated viaducts will be constructed under all directions in the Riia traffic hub to icrease pedestrian safety. In addition, a grade separated highway crossing will be constructed underneath the Jõhvi-Tartu-Valga highway by the roundabout on Aardla Street and Optika Street.
