Upgrading the S8 expressway between Powązkowska and Marki

The project involves building work along an 11.7 km section of the S8 expressway between the Powazkowska and Marki interchanges, forming part of Warsaw’s northern expressway ring road.

Additional tools


The project, together with a further section of the S8 between Konotopa and Powazkowska (now under construction), will connect with the A2 motorway west of Warsaw, creating a bypass for west-north/east transit traffic. The project is part of both the TEN-T network as well as the former Trans European Corridor No 1 (the ‘Via Baltica’) connecting Warsaw, Kaunas, Riga, Tallin and Helsinki.

Upgrading the existing road infrastructure

The purpose of the project is to bring the section of National Road No 8 between the Powazkowska interchange in Warsaw and the Marki interchange in Marki (Mazowieckie Voivodship) up to expressway standard.

For technical reasons the project has been divided into two stages: firstly, the section of the S8 between the Modlinska and Marki interchanges; secondly, the section between the Powazkowska and Modlinska interchanges, including reconstruction of the Grot-Rowecki Bridge (the biggest and most expensive section).

Reduced environmental impact

The construction work includes the widening of the bridge section to allow the separation of the main carriageway from local feeder roads, the building of new carriageways between Modlinska and Labiszynska as well as at the Marki interchange, and the widening of the main carriageway between Labiszynska and Marki. Other project aspects have been incorporated to limit the environmental impact of road traffic (e.g. green spaces with protective/landscaping/aesthetic functions, construction/rebuilding of noise barriers, construction of storm-water conduits, protection of surface water and groundwater).

Part of the bigger picture

The upgraded route is part of a broader investment effort in the form of construction of the S8 expressway, which itself is part of the Trans-European Transport Network (TEN-T) linking Wroclaw with the Lithuanian border near Budzisk. In terms of maintenance along with repairs and management, responsibility for all future operating costs will lie with the project beneficiary, the Directorate-General for National Roads and Motorways.
