Corridor X locally corresponds to the M-1 motorway (E75), which is the longest North Macedonian highway. It also corresponds to the Tabanovce-Gevgelija railway. Corridor VIII, less developed, corresponds to the M-4 motorway and the Kičevo-Beljakovce railway. Skopje is not quite on the Corridor X and the M-1 does not pass on the city territory. Thus the junction between the M-1 and M-4 is  some  east, close to the airport. Although Skopje is geographically close to other major cities, movement of people and goods is not optimized, especially with Albania. This is mainly due to poor infrastructure. As a result, 61.8% of Skopjans have never been to Tirana, while only 6.7% have never been to Thessaloniki and 0% to Sofia. Furthermore, 26% of Thessalonians, 33% of Sofians and 37% of Tiranans have never been to Skopje.
