Crossing Continents on the E80
The D100 highway in Istanbul follows the exact path of the ancient Roman road Via Egnatia, which connected Constantinople to Rome's Adriatic ports. This modern E80 route maintains that transcontinental connection, crossing the Bosphorus Bridge from Asia to Europe before winding through five countries over approximately 2,100 kilometers. The drive requires navigating Turkish mountain passes, Balkan border crossings, and Italian autostradas, with elevation changes from sea level to 1,200 meters in Bulgaria's Balkan Mountains. Local driving quirks include Turkey's frequent speed camera warnings (displayed on electronic signs) and Italy's ZTL (limited traffic zones) in historic centers. For comprehensive planning, consider how to find the best stops and hidden gems between cities to enhance your route planning.
