The roads of Nigeria traverse a territory of sharp contrasts in climate, soil and vegetation. In the swampy areas and dense forests of the South annual rainfall ranges from 80 to 200 inches but is as low as 10 inches in the desert areas of the North. The elevation is seldom more than 2,000 feet, except in the Plateau area around Jos in the Northern Region, and in the Southern Cameroons where there are large inhabited areas over 4,000 feet high.
The length of the road system in 1953 may be estimated at about 29,000 miles, or approximately 77 miles of road per thousand square miles, a high road density for Africa. As shown in Table 1, however, there are considerable variations in density among different parts of the country.
