President Ruto Announces Construction Start for Rironi-Mau Summit Dualing Next Week

The long-awaited dualling of the Rironi–Naivasha–Mau Summit highway is officially set to commence on November 28, 2025, marking a monumental step in the modernization of Kenya's infrastructure backbone.

President William Ruto confirmed the groundbreaking date following a meeting with the President of the China Communications Construction Company (CCCC), highlighting the strategic importance of the 170-kilometre corridor.

This project is poised to drastically transform the movement of goods and people along the Northern Corridor, which serves as a vital trade artery linking Nairobi to Western Kenya, and onward to regional neighbours like Uganda, Rwanda, and South Sudan.

The initiative is structured as a robust Public-Private Partnership (PPP) under a Design-Build-Finance-Operate-Maintain-Transfer (DBFOMT) model, ensuring sustainable management over a 30-year concession period.

The implementation consortium comprises China Road and Bridge Corporation (CRBC), a CCCC subsidiary, alongside the National Social Security Fund (NSSF) Consortium. The participation by NSSF signals significant local investment in the infrastructure development, with the project financed through a mix of debt and equity.

The government has also confirmed that on the same day, groundbreaking will occur for the adjacent 58-kilometre dualing of the Rironi–Maai Mahiu–Naivasha road, further expanding connectivity across the southern transport link.

While the new highway will operate as a toll road, expected to cost motorists approximately Sh8 per kilometre, the government is committed to providing a secure and free alternative route to ensure all citizens retain access to the region.

The commencement of this major highway development heralds a new era for regional trade facilitation and economic growth across the Rift Valley and beyond, promising thousands of jobs and substantial economic stimulation for local communities.
