Project General Description

The Arusha-Namanga-Athi River trunk road forms part of the East African Community (EAC) priority Corridor No.5 of the Regional Roads Network Programme which spans from Tunduma in southern Tanzania/Zambia border to Moyale in northern Kenya/Ethiopia border. The project concept is based on the larger vision of establishing major arterial trunk roads with a regional bearing to facilitate trade and integration of the east African region. It is not new to the Bank. In 2003 and 2006, it already received financing for the feasibility study and detailed engineering design of Arusha – Namanga – Athi River road, which represents the basis for the project design. The project road will facilitate growth in key sectors among which trade and tourism. Also the it will foster economic integration by helping to eliminate physical barriers to cross-border trade and improve the flow of production factors. In addition, the road will promote agricultural production by large and small farmers along the road corridor area. Project construction will be implemented over a period of 36 months starting June 2007 and will be completed by June 2010. The cost estimate (net of all taxes and duties) is UA 98.815 million.

Project Objectives

The project’s core objective is to improve the essential road transport infrastructure between Kenya and Tanzania, particularly between Arusha and Nairobi, Arusha and Mombasa and Malindi and Dar es Salaam. In addition, the project will improve capacity at East African Community Secretariat, and improve contracting capacity for civil works in the region.


The main beneficiaries of the project will be people living in the vicinity of the road in Arusha Region in Tanzania and south Rift Valley Region in Kajiado district in Kenya. Among the major beneficiaries will be tourists who come to the region on both sides of the border, and tourist and hotel operators. Other beneficiaries will be the commercial horticulture farmers from both Kenya and Tanzania who are growing cut-flowers for export. As the road gets closer to Athi River hence outskirts of Nairobi, main beneficiaries will be those operating in the Export Processing Zone (EPZ), the cement factory operators and traders in both animal products and merchandise in general. Officials managing the border posts, local administration and other local government activities will also benefit from the upgraded road.
