Usahihi Expressway: Government Issues Update on Proposed Nairobi-Mombasa Expressway Project

Procurement for the proposed Nairobi-Mombasa Expressway has not yet begun. The Public Private Partnerships Directorate placed the project under transaction advisory in its latest update.

The 461 kilometre road, also known as the Usahihi Expressway, would transform the existing A8 highway into a modern access-controlled toll expressway. It links Kenya’s two largest cities and forms part of the Northern Corridor trade route.

The government listed the project among strategic transport initiatives. However, it remains in the feasibility study and project development category. Critical financial and structuring work is still underway.

This position contrasts with earlier projections. In March, Transport Cabinet Secretary Davis Chirchir told the Senate that a PPP assessment report was being finalised. Detailed evaluations on value for money and financing were ongoing.

A subsequent quarterly report in April suggested the project was advancing toward procurement preparation. Plans then called for publishing a transaction advisor proposal report by the end of April.

The advisor was expected to refine studies, structure financing and package the project for investors. The latest update shows foundational advisory work is still incomplete.

The project carries an estimated cost of Sh466.8 billion. It involves expanding the highway into a minimum four-lane dual carriageway with controlled access and tolling systems.

Everstrong Capital is among the parties involved in earlier discussions around the project. Kenya National Highways Authority has opened some sections of the existing Nairobi-Mombasa highway after upgrades. The full expressway vision has taken longer to materialise.

Highway projects of this scale require extensive preparation. Regulatory approvals, environmental assessments and investor interest all influence timelines.

The government continues to identify the expressway as a priority. Deeper market engagement is expected in coming months.
