S1 Mysłowice (Kosztowy) – Bielsko-Biała (Suchy Potok)
Construction of about 40 km of the S1 expressway on a new alignment between Mysłowice and Bielsko-Biała, under four GDDKiA contracts: Mysłowice – Bieruń, Bieruń – Oświęcim, Oświęcim – Dankowice and Dankowice – Suchy Potok. The contracts are worth almost PLN 2.3 billion in total. The sections from Oświęcim to Bielsko-Biała opened in 2025, and the Bieruń – Oświęcim section opened to traffic in March 2026 and fully in September 2026. The 10 km Mysłowice – Bieruń section is still under construction, with progress above 66 per cent and completion planned for the fourth quarter of 2027.

Significance
Once Mysłowice – Bieruń is finished, the S1 will be a continuous expressway from Pyrzowice airport to the border at Zwardoń, continuing along the Slovak D3 motorway. GDDKiA reported EU co-financing of almost PLN 441 million for the Oświęcim – Suchy Potok section (agreement of 19 June 2023). GDDKiA attributes the delay of the last section to longer administrative procedures and the contractor's time claims.

Independence is counted the same way the gate that admits a record counts it: subdomains and titles from one publisher are a single voice, Wikipedia is zero. That is why the number is lower than the number of links. Three is the minimum.
