droga ekspresowa S8, Trasa Bohaterów Bitwy Warszawskiej 1920 r.[1]) is a Polish highway which connects Wrocław via Łódź and Warsaw to Białystok.

Its fragment forming the bypass of Wrocław (22.7 km) is constructed in motorway standard and marked as A8.

As such, it might be considered not to fully meet the definition of a bypass as it serves both the transit and local district traffic at the same time.

In effect, large traffic jams form on this section every day in the peak hours.

[7] S61 and the section of S8 from Warsaw to the S61's starting point serve as part of Via Baltica.
