CAMEROON’S INFRASTRUCTURE: A CONTINENTAL PERSPECTIVE Only 67 percent of the Douala-Ndjamena corridor is paved. This means that neither the Central African Republic nor Chad can rely on these corridors as all-weather connections to the sea (table 4).

Furthermore, only 48 percent of the Douala-Bangui corridor, 21 percent of the Pointe NoireBrazzaville-Bangui corridor, and 52 percent of the Douala-Ndjamena corridor are in good condition. In each of these cases the problem seems to lie in the neglect of road quality by Cameroon. Only 30 percent of the Cameroonian section in the Douala-Bangui corridor is in good condition, against 100 percent of the Central African section. A World Bank project currently underway aims to substantially improve the quality and efficiency of this corridor; most recent data suggest that as of 2011 60 percent of the corridor was in good condition.

Similarly, only 56 percent of Cameroon’s section of the Pointe Noire-Brazzaville-Bangui corridor is in good condition (and none of the Republic of Congo’s section is in good condition), whereas 100 percent of the section in the Central African Republic is in good condition. All of the Douala to Ndjamena corridor is located in Cameroon (table 4). Clearly, the incentives for Cameroon and other coastal countries to maintain hinterland road corridors are not very strong. Coastal countries’ economies are typically concentrated along the coast, making the up-country segments regional public goods.

Note: The summation of the good, fair, and poor condition not necessarily add up to 100 since there might be some links the condition of which is unknown. The summation of the paved and unpaved type does not necessarily total 100 as the type of some links may be unknown. a. Asphalt and surface treatment pavements are considered paved roads.

b. The condition of the Douala to Ndjamena corridor is from World Bank (2011c).
