Gastarbeiterroute is a German language slang term originating in the 1970s. It referred to the former European route 5, which started in Munich and terminated in either Istanbul or Thessaloniki. In summer, as well as for Christmas and Easter, so-called gastarbeiters working in West Germany, Austria and Western Europe would drive their automobiles south on the gastarbeiterroute through Austria and Yugoslavia to their countries of origin. It was notoriously dangerous for drivers and passengers who traveled on congested roads not suited to such heavy traffic.
