It is planned to extend S1 north along the existing dual carriageway DK1 from Bielsko-Biała to Tychy and Katowice, thus building an expressway connection of the city with the national motorway network of Poland. National road 52 connects Bielsko-Biała with Kraków in the east. The most important interchange in the area is the cloverleaf north of Bielsko-Biała (Komorowice Śląskie district) where S1, DK1 and S52 meet.
