Expressway S5 or express road S5 (Polish: droga ekspresowa S5) is a Polish highway which runs from Grudziądz (connecting to motorway A1 towards Gdańsk) through Poznań (partial concurrency with motorway A2) to Wrocław (connecting to motorway A8).
The expressway was constructed between 2009 and 2022. Its total length is about 353 km (219 mi).
In 2015, it was announced that S5 will be further extended from Grudziądz to Ostróda (connecting to S7). In 2019, an extension from Wrocław to Bolków (connecting to S3 near the border with Czech Republic) was added to the plans. Both extensions are intended to be completed as part of the road construction plan until 2033,[1] which will increase the total length of the expressway to about 508 km (316 mi).
