President William Ruto has launched the Sh170 billion Nairobi–Nakuru–Mau Summit and Nairobi–Maai Mahiu–Naivasha highways projects, expected to create 15,000 jobs for young Kenyans. The initiative signifies a major shift towards Public–Private Partnership (PPP) financing for infrastructure development.

• The 233-kilometre corridor, a vital East African transport route, will improve efficiency and reduce accidents.
• President Ruto emphasized that the project prioritizes local contractors, skills transfer, and SME involvement.
• Key features include a dual carriageway upgrade, Intelligent Transport Systems (ITS), and enhanced sections for heavy cargo flow, boosting logistics around the Naivasha Inland Depot.

President William Ruto has officially launched the dualling of the Rironi–Nakuru–Mau Summit Road, a critical infrastructure project set to transform the 170-kilometre corridor linking Nairobi to the Rift Valley and western regions of Kenya.

• The project is a public-private partnership involving China Road and Bridge Corporation (CRBC) and the National Social Security Fund (NSSF).
• The road will feature a four-lane dual carriageway from Rironi to Naivasha and a six-lane dual carriageway between Naivasha and Nakuru.
• Scheduled for completion by June 2027, the upgrade aims to reduce congestion, improve safety, and boost economic integration by lowering transport costs.

President William Ruto launched the Nairobi-Nakuru-Mau Summit Road (A8) and the Nairobi-Mai Mahiu-Naivasha Project in Kiambu County on November 28, 2025, hailing it as a "dawn of a new era" for Kenya due to its debt-free financing model.

• The project represents an investment of over 170 billion shillings, utilizing a world-class Public-Private Partnership (PPP) model.
• The highway comprises two sections: the 175-kilometer Nairobi-Nakuru-Mau Summit Road and the 58-kilometer Nairobi-Maai Mahiu-Naivasha Road.
• The project is expected to create 15,000 jobs for young Kenyans during construction.
• Future plans include extending the Standard Gauge Railway (SGR) from Naivasha to Kisumu and Malaba, starting in January 2026.
