Project General Description

The Isebania-Kisii-Ahero Road Rehabilitation, which forms part of the A1 road connecting with Tanzania in the south and South Sudan in the north, will facilitate cross border movement of passengers and freight, and expand regional market size. It is a transit route running along the Eastern shore of Lake Victoria via Isebania to Lokichogio onwards to Juba and the main trade route between Mwanza port (Tanzania) and Kisumu port (Kenya)-the key trading centres within the Lake Victoria basin. The project entails: improvement of Isebania-Kisii-Ahero road (172km) and upgrading of feeder roads (77km) connected to the main roadway; assessment of domestic construction industry capacity; analysis of transport infrastructure gap in Kenya; and Technical Assistance to update Road design Manuals, establishment of post-crash care and injury recovery centre, road crash database, and empowerment of small-to-medium women and youth contractors through targeted training—to improve capacity for road maintenance. Ancillary works include: community water supply; roadside markets to improve local business environment and road safety. The Project is estimated to cost USD 280.26 million, and Construction period is 3 years (2016–2019).

Project Objectives

The Development objective of the Project is to promote inter-regional and domestic trade and in doing so, contribute to the GoK’s socio-economic development and poverty reduction efforts by improving access to markets and enhancing transport efficiency. The specific objective is to improve regional transport connectivity by expanding and improving road infrastructure (both trunk road and feeder roads) in order to facilitate freight and safe passenger transport along the Sirari Corridor (Tanzania-Kenya-South Sudan), and within the Lake Victoria basin.


Beneficiaries include 2 million people directly served by the road network, poised to benefit from expanded market size and improved access to social services. The overall beneficiaries shall be transporters and vehicle owners operating on the road, local population (consumers, producers, traders etc.), investors, Kenyan public administration, and security sectors.
