Berettyóújfalu is a town in eastern Hungary notable for being the junction between the N47/E79, running between Debrecen and Szeged, and the N42/E60 which goes between Budapest and the Romanian border at Oradea.
East towards Romania
The Ártánd-Borş border crossing with Romania is about 25 km from here.
Many cars passing through here belong to western Romanians who come to Hungary for shopping and are only going to Oradea. If your destination is further east into Romania, it may be better to use a sign (e.g. "CJ" for Cluj-Napoca).
