The project will contribute to the improvement of connections of secondary and tertiary nodes such as Rabka Zdrój, Zakopane, Nowy Targ and Jabłonka on the Polish side and the Tvrdošín and Trstená tertiary nodes on the Slovak side with the main roads, that is the A4 motorway in the Małopolskie Voivodeship and the D1 motorway in SK. This will reduce the travel time between these towns and the TEN-T roads. The driving comfort and safety of road users will be improved. The project eliminate the bottleneck in the borderland communication network on roads II/520 and voivodeship road (DW) no. 959. Extending road no. III/2311 from Oravice to Zuberec is essential, in particular from the perspective of passenger transport. Zuberec, as the central resort of the Western Tatras with a great number of accommodation facilities, is considered a tertiary node, also because of its connection to the TEN-T corridor in the direction towards Podbiel. In the light of the above, the road network in the Zuberec area is characterised by relatively high traffic intensity. Also in the opposite direction, there is a connection from Zuberec to an international TEN-T corridor – road no. II/584 – which leads through the Huty mountain passage, passes the Liptovská Mara dam, and reaches the Liptovský Mikuláš secondary node. This route is generally known as a highly popular road connection, not only from the tourist viewpoint, but also because it provides a relatively quick connection between Orava and Liptov. Furthermore, Zuberec – as the gateway to the Western Tatras – is a vital traffic centre of international significance; it offers a wide range of services to the local population, including healthcare and emergency services that cover a wider area. Trstená is located on the route incorporated into the TEN-T network. It is a city of fundamental importance for the whole county, as the Upper Moravian Hospital is located here, providing healthcare services for the residents of the wider area.
