Zurich Process


The motorway known as the Pyhrn corridor connects Linz / Wels (junction Voralpenkreuz, Austria) with Graz (AT) and Maribor (SI) and is thus an important link for transit and holiday traffic crossing the Alps in the north-south direction. The Austrians section of the corridor consists of the A9 motorway, and the Slovenian section of the A1 motorway Štajersko-primorska avtocesta.
