Inadequate transport facilities are a considerable impediment to Somalia’s economic development. There are no railways. Only about 1,800 miles (2,900 km) of paved roads are passable year-round, and in the rainy seasons most rural settlements are not accessible by motor vehicle. Buses, trucks, and minibuses are the main means of transport for the population. In rural areas camels, cattle, and donkeys are still used for personal transportation and as pack animals.
