Kenya, east Africa’s largest economy, has begun the $960-million process of constructing and upgrading two key roads in the capital of Nairobi through public/private partnerships as part of the multinational Northern Corridor Transport Improvement Project (NCTIP). On Feb. 24, the country signed an agreement with G8 member-country Japan for partial funding of the construction of the Nairobi Western Ring Road. Japan gave Kenya an initial $420,000 grant for the project. NCTIP is a multibillion-dollar road and air-transport program that aims to link the Great Lakes countries, with an estimated combined population of 120 million, to Kenya ’s seaport of Mombasa.
