trans-African highway starts from Mombasa and it ends at Lagos connecting E. African countries, central African countries and W. African countries with a distance of 6,500km.

The idea for construction started in 1971 by OAU countries at a cost of 300m dollars with assistance from World Bank, European Union, OAU member countries.

It covers countries like Kenya, Uganda DRC, Central African Republic, Cameroon, and Nigeria.


  • Trans-African highway is not yet successful, some areas in DRC, central African Republic, Gabon are not complete because it is affected by physical and human problems.
  • Political instability and insecurity because of rebel activities in DRC scaring investors and workers.
  • Presence of rugged and steep slopes in highlands and mountains increasing on expenses for construction.
  • Equatorial forests in the DRC, Gabon, C.A.R delaying construction work.
  • Wet equatorial climate affecting construction and increasing on expenses.

  • Poor drainage around R. Congo and its tributaries like R. Kasai, Ubanju, Luluaba, Ebora and swampy areas.
  • Poor international relations and regional corporation between Frank Forne countries and Anglo Forne countries.
  • Poor science and technology leading to limited skilled labour leading to increased costs of using expatriates.
  • Presence of wild animals in DRC, Gabon, CAR, animals like lions.
  • Low population leading to shortage of labour and limited economic activities.
  • Limited capital by OAU member countries to finance the construction.

  • Presence of hostile tribes like the Pygmies scaring investors and workers
  • Weakness of OAU in implementing its aims and objectives with a lot of conferences, meetings.
  • Sabotage by developed countries and multinational companies like British Airways, Air France.
  • Competition with other transport systems like Air, Water, railway transport and
  • countries using Indian ocean like E. Africa countries and W. Africa countries using Atlantic ocean
