The population is centered around Ioannina, which has the largest number of industrial establishments. Transportation Epirus has historically been a remote and isolated region due to its location between the Pindus mountains and the sea. In antiquity, the Roman Via Egnatia passed through Epirus Nova, which linked Byzantium and Thessalonica to Dyrrachium on the Adriatic Sea. The modern Egnatia Odos highway, which links Ioannina to the Greek province of Macedonia and terminating at Igoumenitsa, is the only highway through the Pindus mountains and has served to greatly reduce the region's isolation from the east, while the Ionia Odos highway, connecting Epirus with Western Greece, helped reducing the region's isolation from the south. Also, the Aktio-Preveza Undersea Tunnel connects the southernmost tip of Epirus, near Preveza, with Aetolia-Acarnania in western Greece. Ferry services from Igoumenitsa to the Ionian islands and Italy exist. The only airport in Epirus is the Ioannina National Airport, while the Aktion National Airport is located just south of Preveza in Aetolia-Acarnania. There are no railroads in Epirus.
