CS Chirchir: Dualling of Rironi-Naivasha road to be complete by October 30

“By October 30, from Rironi to Naivasha, we will have completed the dualling and opened the road to traffic,” CS Chirchir said after a development tour in Bomet County on Wednesday.

The Transport Cabinet Secretary added that the construction would proceed to the Naivasha–Nakuru section, followed by the escarpment section from Kamandura.

“We will afterwards continue constructing the Naivasha–Nakuru section, as well as the escarpment section from Kamandura,” added the CS.

The two-phase construction of the Ksh.184 billion project was launched by President William Ruto in November 2025 to ease congestion and improve safety along the busy transport route.

The two phases are: The first phase (A8 road) will run from Rironi through Naivasha to Gilgil, and the other (A8 South road) will run from Rironi through Mai Mahiu to Naivasha. 

The second phase will run from Gilgil to Mau Summit through Nakuru.

The project is undertaken by the China Road and Bridge Corporation (CRBC) and Shandong Hi-Speed Road and Bridge International, in partnership with Kenya’s National Social Security Fund (NSSF).

The road will start at Rironi as a four-lane dual carriageway up to Naivasha.

From Naivasha to Nakuru, where traffic volumes are highest, the highway will widen into six lanes on each side to accommodate heavy commercial and passenger traffic. Through Nakuru town, the road will be elevated.
