The county is connected by a well developed system of expressways and motorways. The main west–east corridor is Rruga Shtetërore 2 (SH2), which connects the country's capital Tirana with the country's second largest city Durrës in Durrës County. The north-south corridor is Rruga Shtetërore 3 (SH3), which is currently being transformed into the Autostrada 3 (A3), covering the distance between Tirana and the country's fourth largest city Elbasan in Elbasan County. Rruga Shtetërore 4 (SH4) passes through Kavajë in the west from north to south linking Durrës with Greece. However, after its completion, the Arbër Highway will connect the county with Dibër County and North Macedonia.
