Statoil, the Norwegian National Oil Company, own a petrol station in Lebork in Northern Poland, as part of a chain of 160 petrol stations in Poland. The access road to this petrol station crosses a Jewish cemetery, where all the gravestones were removed in the Nazi era. Arieh Klein developed a solution to rebuild the access road, with a steel structure providing an 'air-gap', so that it will satisfy the demands of Jewish Halachic law.
