Via Carpatia



The Three Seas Initiative is an economic and political project that originated in 2015. It was put forward by Kolinda Grabar-Kitarović, then President of Croatia, and Andrzej Duda, President of Poland. Sometimes it is also called the ‘ABC Initiative’, where ‘ABC’ is the acronym of the Polish names of the seas enclosing the region. The twelve participants of the Initiative are Austria, Bulgaria, Croatia, the Czech Republic, Estonia, Lithuania, Latvia, Poland, Romania, Slovakia, Slovenia and Hungary.

The aim of the Three Seas initiative is to boost the economic development of its members by expanding the network of connections in the power sector, infrastructure and digital services. Poland, together with Croatia and Hungary, is one of the pioneers in the implementation of key projects and currently takes part in ten such projects, the construction of Via Carpatia being one of them.

Via Carpatia is a new transnational communication route connecting the eastern countries of the EU from Klaipeda in Lithuania to Thessaloniki in Greece and farther on to Istanbul, Turkey. The road will pass through Poland, Slovakia, Hungary, Romania and Bulgaria. The first declaration concerning Via Carpatia had been signed even before the Three Seas Initiative came into being – in 2006 in Łańcut by ministers of transport of Poland, Lithuania, Slovakia and Hungary. The project gained momentum after the Three Seas initiative was born. In 2018, ministers of transport of the Via Carpatia transit countries applied to the European Commission to include the Via Carpatia project in the trans-European transport network programme TEN-T aimed at the development of roads, railway, waterways and airways. As many as 5 out of 9 TEN-T corridors are passing through the Three Seas countries, including such major corridors as Baltic-Adriatic, Rhine-Danube and North Sea-Baltic Sea.

The construction of Via Carpatia tallies with the process of strengthening the economic and territorial cohesion of the region. The project is intended to eliminate disparities in the development of infrastructure in Europe. According to the declaration of governments of the 3SI states, completion dates for national sections of the route are: 2022 in Hungary, 2023 in Slovakia, and 2025 in Poland. The most important Polish section will be the S19 expressway of the length of 580 km, passing through Podlaskie, Mazowieckie, Lubelskie and Podkarpackie voivodships.

Via Carpatia will function as the ‘spine’ of the Three Seas region. Its branches will also reach the port of Constanta in Romania and the city of Svilengrad in Bulgaria, stimulating the development of regions not directly situated along the route. In the territory of Poland, the course of Via Carpatia coincides with a fragment of Via Baltica leading from Poland through Lithuania and Latvia to Tallinn in Estonia. This will make it the major communication axis of the Baltic states.

Via Carpatia will be one of the topics addressed during the Local Government Economic Congress of the 2nd Three Seas Initiative Forum to be held between 29 and 30 June 2021 in Lublin. Apart from obvious economic benefits and infrastructure development, Via Carpatia also offers the opportunity for the promotion of tourism in the Three Seas region. During the Congress, international specialists will present best practices of the tourist industry in the 3SI countries and propose innovative solutions related to the promotion of tourism products. The participation of local governments of the 3SI countries in the Forum will make it possible to exchange experiences, make regional co-operation closer and strengthen and improve the joint policy of the region in the field of tourism.

The Three Seas Local Government Congress under the Honorary Patronage of the President of Poland



The 6 th edition of the Three Seas Local Government Congress will be held May 27-28, 2026, under the Honorary Patronage of the President of the Republic of Poland, Karol Nawrocki. This distinction recognises the growing importance of the event, which has become a key platform for cooperation among the countries of Central and Eastern Europe, both in the economic and infrastructural dimensions.



Over five editions of the Congress (2020–2025), more than 5,000 participants from 24 countries have taken part, 104 discussion panels have been held, and 64 foreign delegations have visited Lublin. The scale and international character of the event confirm its increasing role in shaping dialogue across the Three Seas region.




We, the countries representing Central and Eastern Europe (…) through the Three Seas Initiative, Via Baltica, and Via Carpatia, share not only our voice and vision of building a civic community, but also tangible results showing that the Baltic States and the countries of Central and Eastern Europe are capable of implementing major infrastructure projects, emphasised President Karol Nawrocki during his visit to Vilnius last month.



These words perfectly capture the spirit of the Three Seas Congress, which brings together political, academic, and business communities around a shared goal, building a strong, integrated, and cooperative Central and Eastern Europe.



It is also worth noting that in April 2025, Poland hosted the 10th Three Seas Initiative Summit. During the event, participants emphasised the importance of infrastructure and economic cooperation in the region and the need to strengthen cohesion across Central and Eastern Europe. This year, the cooperation format has been expanded to include new members – Albania and Montenegro joined the Three Seas Initiative in the capacity of associated participating states, while Spain and Turkey became new strategic partners. It has already been announced that the 11th Summit will take place in Croatia in 2026.



We cordially invite you to take part in the Three Seas Local Government Congress! Registration will open in the end of January. More details will soon be available at www.congress.lubelskie.pl and on our social media channels.
