Nairobi–Mombasa Expressway Project
The Public–Private Partnership (PPP) Committee recently rejected the proposal for the ambitious Nairobi–Mombasa Expressway, popularly branded as Usahihi stating that it did not meet the legal and technical requirements.
The 459-kilometre toll road was expected to link Mlolongo in Machakos to Bonje in Mombasa.

Initially pegged at an estimated cost of Ksh460 billion, the project was to be developed under a PPP model, with construction projected to begin in the first quarter of 2026.
However, in July 2025 the PPP Committee ruled that the proposal did not meet the threshold set out under the PPP Act.
It directed that the project be halted and directed KeNHA to restructure it.
