National road No. 7, DK 7 in Polish, is a route of the Polish national roads network running from Żukowo near Gdańsk, through Warsaw and Krakow to the border with Slovakia at Chyżne. It is part of European route E77. The stretch between Krakow and Zakopane is commonly referred to as Zakopianka.
Since the beginning of 1990s parts of the DK 7 were being rebuilt to expressway standards and now form part of the Expressway S7. The section around Krakow is concurrent with Autostrada A4 motorway.
Prior to its modernisation, the DK 7 was the most dangerous road in Poland along the with DK 1.
Since the project was launched, over 35,000 bonded anchors have been installed in R-CAS-V-16 capsules, in a system with R-STUDS-16190-88HD threaded rods. Installation took place in multiple locations, including a bridge on the S7 road in Krakow, the longest bridge in this part of Poland.
