The 170-kilometer Rironi–Mau Summit Highway was launched by President William Ruto on Friday, November 28, 2025.
The project is being implemented through a Public-Private Partnership between the China Road and Bridge Corporation (CRBC) and the National Social Security Fund (NSSF).
Construction is scheduled to take two years at a cost of USD 863 million (Ksh170 billion), followed by a 28-year operation period.
The highway will include interchanges, truck lay-bys, pedestrian bridges, improved lighting, barriers, drainage systems, and intelligent transport technology to enhance road safety.
From Rironi to Naivasha, the road will have four lanes, expanding to six lanes from Naivasha to Nakuru.
