On behalf of the Cameroon Ministry of the Economy, Planning and Urban Development, DTP constructed the first 86-kilometre stretch of a road linking Garoua Boulai and Ngaoundéré. The purpose is to reduce the time and cost of transport on the unpaved final section of the Garoua Boulai – Ngaoundéré road network, providing access to the regional corridor linking the port of Douala to the capitals of Chad and the Central African Republic, which do not have sea access. The works consisted of asphalting the road over a 7-metre width and rebuilding five engineering structures.
