The construction of the Rironi-Mau Summit road project was launched by President William Ruto in November 2025.

The project, which is being implemented through a Public-Private Partnership between CRBC and NSSF, will be constructed over two years at a cost of $863 million (Ksh170 billion), followed by a 30-year operation period.

On August 20, Interior Principal Secretary Raymond Omollo said the construction of the road is advancing smoothly from both ends. 

The Interior PS noted that the Rironi-Mau Summit road project is targeted for completion by June 2027. 

“Supervised by the Kenya National Highways Authority (KeNHA) and targeted for completion by June 2027, the project is being delivered through a dual-front approach, with construction advancing simultaneously from both ends,” he said. 

Omollo mentioned that the Rironi–Naivasha section will become a four-lane dual carriageway, while the Naivasha–Nakuru section will be a six-lane highway. 

He also said an elevated bypass will be constructed through Nakuru City to ease urban congestion. 

Further, PS Omollo highlighted that the road project is expected to reduce travel and transit times along the corridor. 

“This transformation means safer travel, shorter transit times and stronger trade along a corridor that carries more than 30% of cargo destined for the larger Western Kenya Region, Uganda, Rwanda, South Sudan and the DRC,” PS Omollo added.
