Getting around in Belgium should be easy and streamlined, with the country boasting a comprehensive network of well-developed road, air, rail and water transportation systems. Belgium’s rail network alone comprises almost 3,000 kilometres of electrified tracks. Within the country there are almost 120,000 kilometres of roads, including almost 1,800 kilometres of motorways, 14,000 kilometres of main roads and 103,000 kilometres of other paved roads. In terms of waterways, Belgium has a network of 2,000 kilometers of canals, most of which are in regular use. Amongst the busiest waterways is the Albert Canal, which connects the city of Antwerp to Liège, the Ghent-Terneuzen Canal, which links the port of Ghent to the Westerschelde and the Boudewijn Canal, which connects Bruges to the North Sea. Belgium also has a total of 43 airports, although only 5 of these are available for passenger airlines.
