The Northern Corridor, connecting East Africa to the World through the port of Mombasa, is one of the oldest corridor authorities in Africa, as it was established in 1985. Throughout its years of existence, it has been a source of ideas and knowledge that contributed to the thinking on trade facilitation. To a large extent, it is the birthplace of the concept of corridor transport observatory, and through successive models and revisions, it helped shape what transport observatories are. Transport Observatories emerged as the result of the efforts made over the years to address the specific challenges faced by landlocked developing countries. Most of these countries rely heavily on overseas markets as outlets for their productions and as source for their imports, but for that, they must transit through a coastal country. They are at a disadvantage when it comes to competing on equal terms with other economies for integrating into the world market. The handicaps attached to that remoteness are well known and many: a longer time to import or export, a time rarely predictable, higher costs, with sometimes a double toll when input into production must also be imported. Moreover, little can be done by the landlocked countries alone to improve the conditions of crossing transit countries. Indeed, transit trade flows may even be considered as a nuisance or even a threat when similar economies are competing for similar markets.
