Autostrada A18 is a short motorway in southwestern Poland which runs from the Polish/German border at Olszyna/Forst-Bademeusel 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.
The Reichsautobahn from the 1930s had served as the east-bound carriageway until 2021.
A short fragment of A18 (5.6 km) remains substandard due to lack of emergency lanes.
The A4 autostrada in Poland is a 669 km (416 mi) long east–west motorway that runs through southern Poland, along the north side the Sudetes and Carpathian Mountains, from the Polish-German border at Zgorzelec-Görlitz, through Wrocław, Opole, Gliwice, Katowice, Kraków, Tarnów and Rzeszów, to the Polish-Ukrainian border at Korczowa-Krakovets. It is a part of European route E40.
