Two consortiums have made progress In the Nairobi–Nakuru–Mau Summit Highway PPP Project, following the acceptance of two Project Initiation Proposals (PIPs).
The latest development marks a critical phase of the project, with the Kenya National Highways Authority (KeNHA) approving Project Initiation Proposals (PIPs) from two main consortia on July 2, 2025.
The China Road and Bridge Corporation (CRBC) in partnership with the National Social Security Fund (NSSF), and Shandong Hi-Speed Road & Bridge International Engineering Company Limited (SDRBI) are the firms approved for the project.
The multibillion-shilling road project will now move on to the Project Development Phase for both groups.
The PPP include managing and improving the Rironi–Mai Mahiu–Naivasha (A8 South) segment as well as the Nairobi–Nakuru–Mau Summit (A8) highway.

The 231-kilometer corridor, which supports a significant amount of regional and international cargo traffic, links landlocked East and Central African nations to the Port of Mombasa and is an essential component of the Northern Corridor and the Trans-African Highway.
The A8 South section, which spans approximately 56.4 kilometres from the Rironi Interchange to the Naivasha Interchange via Mai Mahiu, is a key component of the project.
It serves as an alternative route to the escarpment and complements ongoing infrastructure development in the region.
The move marks a major step forward for one of Kenya’s flagship PPP infrastructure projects aimed at enhancing trade, mobility, and economic integration across East Africa.
