The Gambia River not only provides important internal transport but is also an international commercial link; oceangoing vessels can travel 240 km (150 mi) upstream. In 2002 there were 400 km (249 mi) of total waterways. Banjul, the principal port, receives about 300 ships annually. Ferries operate across the river and between Banjul and Barra.
With the construction of major all-weather roads on both sides of the Gambia River, the waterway has become less significant for passenger traffic. As of 2002, there were 2,700 km (1,678 mi) of roads, including 956 km (594 mi) of paved roads; 106,600 passenger cars and 142,300 commercial vehicles were in use. The Gambia has no railroads. There is an international airport at Yundum, 26 km (16 mi) from Banjul. Air Gambia, 60% state owned, acts as an agent only; foreign air carriers provide international service.
