Controlled-access highways in Poland are part of the national roads network and they are divided into motorways and expressways. Both types of highways feature grade-separated interchanges with all other roads, emergency lanes, feeder lanes, wildlife crossings and dedicated roadside rest areas. Motorways differ from expressways in their technical parameters like designated speed, permitted road curvature, lane widths or minimal distances between interchanges. Moreover, expressways might have single-carriageway sections in case of low traffic densities (as of 2025, such sections constitute 3% of the highway network).
The development of modern highways began in the 1970s, but proceeded very slowly under the communist rule and for the first years afterwards: between 1970 and 2000 only 434 km of highways (5% of the planned network) were constructed in total. Further 1050 km (13% of the network) were opened from 2001 to 2010, followed by 2773 km (34% of the network) constructed between 2011 and 2020. It is planned to open about 2500 km (31%) in the 2020s, while the last about 1400 km (17%) would be completed in the 2030s.
