Construction of the 23.4 km Police – Goleniów section of the S6 expressway, part of the Szczecin Western Bypass. GDDKiA signed the PLN 5.3 billion contract on 22 May 2026 with a consortium of NDI, Doğuş İnşaat ve Ticaret and Dogus Construction Poland. It is the largest contract by value in GDDKiA's history. The key element is a 5 km twin-bore tunnel under the Oder, driven by a TBM, the longest road tunnel in Poland. The contract allows 10 months for design and 80 months for works. Boring is due to start in the second half of 2028 and the whole route is due to open in 2033.

Significance

The new S6 will close the expressway ring around Szczecin. The drive from Police to the Goleniów Północ interchange will shrink from 58 km to 23 km, and a large share of traffic will leave central Szczecin, including vehicles heading for the chemical works in Police. The first stretch, 1.5 km to the Police interchange with a link to the Police bypass, is due to open in 2029.

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.
