Autostrada A18 is a short motorway in southwestern Poland which runs from the Polish/German border at Olszyna/Forst-Bademeusel (connecting with the German Bundesautobahn 15) to the Polish Autostrada A4. The highway is 76.5 km (47.5 mi) long and is part of the European route E36 and the Pan-European corridor IIIA from Berlin to Wrocław. Since 2023, both carriageways are opened after reconstruction and signed as A18.
