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).
The construction of the road received higher priority after Poland was selected as one of the hosts of the UEFA Euro 2012 championship, since it would have provided a direct connection between three of the four Polish cities hosting matches: Poznań, Wrocław and Gdańsk.
However, plans to finish the road before the championship were proven too optimistic and only a section between the A2 motorway and Gniezno (35 km), opened on 4 June 2012, was completed by that time.
In October 2015, the planned future route of the expressway has been extended from the Nowe Marzy junction (near Grudziądz) to Ostróda.
