The ambitious Nairobi-Mombasa Expressway Project, which was to cost Ksh468 billion, has faced a major setback after the Public-Private Partnerships (PPP) Committee rejected its development proposal.

The expressway dubbed Usahihi Express was intended to be a 419-kilometre, four-lane highway connecting Nairobi to Mombasa.

The project was initiated under a PPP by Everstrong Capital, a US-based infrastructure investment firm.

In December 2023, Everstrong was approved to proceed to the Project Development/Feasibility Study stage.
