PORR has been awarded a contract by the General Directorate for National Roads and Motorways (GDDKiA) to deliver part of the Szczecin western bypass (ZOS), one of Poland’s largest ongoing road infrastructure projects. The company will design and construct the Kołbaskowo–Dołuje section, a stretch of more than 13 km, with works scheduled to be completed within 41 months. The contract is valued at approximately EUR 150 million (PLN 631 million).
The scope of the contract covers the planning and construction of a new dual-carriageway expressway with two lanes in each direction, forming part of the S6 route around Szczecin. In addition to the main carriageway, the project includes two interchanges at Będargowo and Dołuje, 18 engineering structures and a road maintenance facility near the Siadło Górne junction. Eight of the structures are designed as wildlife crossings.
The Kołbaskowo–Dołuje section will connect to the second phase of the Przecław–Warzymice bypass along national road DK13, providing a new link to the A6 motorway. Along the route, the bypass crosses several existing roads and railway lines. The largest structure on this section is a 284-metre bridge over the Szczecin–Stobno Szczecińskie–Lübeck railway line. The route then continues northwards and ends near Wołczkowo.
According to PORR, the S6 western bypass is intended to improve traffic flow and safety in the Szczecin metropolitan area and to strengthen transport links in north-western Poland, while incorporating environmental protection measures into the design and construction process.
PORR has previously completed more than 600 km of road projects for GDDKiA across Poland. In the north of the country, its recent work includes a 1.5 km section of DK11 between the Janiska roundabout and the Kołobrzeg East junction, opened in 2024, and a 10 km stretch of the S6 between Bożepole and Luzino, completed in 2022. The company is also involved in bypass projects in Wałcz, Szwecja and Złocieniec.
In addition to road construction, PORR delivered the Świnoujście tunnel in 2023. The tunnel, built beneath the Świna Strait using a tunnel boring machine, created the first permanent road connection between the islands of Usedom and Wolin, replacing the previous reliance on ferry services.
