Bulgaria is also a transport crossroad, affording access to Western Europe, the Near East and the Middle East, and the Mediterranean. A series of major European transport corridors pass through Bulgaria. These corridors include the international highways that connect Western and Central Europe the Near East and the Middle East (through Beograd to Sofia and Svilengrad), including connections to Baghdad and Basra on the Persian Bay; from the Baltic Sea to the Aegean Sea (from Moscow to Kiev, Bucharest, Ruse, and Stara Zagora to Thessaloniki) and to the Adriatic Sea (from Sofia through Skopje to Drach). Another important transport route is the road from Constanta to Varna, Burgas, Tsarevo, Malko Tarnovo and Istanbul. Bulgaria is also connected to the Trans-European networks that lead from Berlin to Prague, Budapest, Sofia, Thessaloniki, and Istanbul and from Durres to Tirana, Skopje, and Sofia to the Black Sea ports of Varna and Burgas. These transport corridors are also serviced by rail. Bulgaria’s Black Sea ports connect with all other countries that border the Black Sea countries, offering particularly excellent opportunities for the development of transport through the large bays that front Burgas and Varna. Along the Danube River the country connects with the transport corridor that leads to the Rhine and the network of waterways that crisscross Western Europe.
