Polish contractor
The section runs from the Wysokie junction to Raczki, the national highways authority GDDKiA announced.
Budimex bid just over €484 million for the 29-month design-build contract.
Last summer, the Italian contractor Impressa Pizzarotti picked up a deal for 24km of the S61 from Suwalki to the border with Lithuania for around €144.6 million, according to media reports.
The S61 is part of the greater European route E 67 running from Prague in the Czech Republic to Helsinki in Finland by way of Poland, Lithuania, Latvia and Estonia. It goes via Prague, Warsaw, Riga, Tallinn and – by ferry – Helsinki, a length of nearly 1,700km.
It is also known as the Via Baltica between Warsaw and Tallinn, a distance of 970km. Most of the route is not motorway but some sections, such as the one in Poland, are dual carriageway.
