Access to sea
There are two major Black sea ports – Varna and Burgas. The river Danube is both a Bulgarian and an international waterway.
Five pan-European transport corridors pass through Bulgaria (a series of ten multimodal transport systems were designed to connect the original Trans European Network (TEN) to the infrastructure of the acceding countries).

Railway network
Of the 4,292 km of railroad lines in use in 2002 about 94% were standard gauge (1435mm), the rest were narrow gauge (960mm). Approximately 22% of the network is double track and just over 61% is electrified. Most of the rail network is designed for speeds of 80-100km per hour.

Road network
The total length of the national road network is 37 288km and the average density is 0.33km per sq. km. According to the Roads Act ( SG No76/06.08.2002), roads in Bulgaria are divided into two main categories – national roads and local roads. National roads comprise all motorways and roads of grades I, II and III (roads carrying at least 1000 to 6000 cars daily). Approximately 90% of the roads are covered with asphalt.

Air transport
Bulgaria has ten civil airports, four of which have international status. The other six serve agricultural aviation. Air transport activity at the moment is concentrated in Sofia, Burgas and Varna. These airports  serve primarily international routes.
