Rironi-Mau Summit Road: How Ruto’s Ksh200B Highway became a 2027 political test

The Ksh200 billion Rironi-Mau Summit highway, spearheaded by President William Ruto, is rapidly becoming a pivotal infrastructure project ahead of the 2027 General Election. Despite initial promises of transformation, the project is now under intense public scrutiny due to construction setbacks, proposed toll charges, and financing concerns.

On October 31, 2026, Roads and Transport Cabinet Secretary Davis Chirchir attributed delays to a shortage of bitumen, citing geopolitical issues and supply chain disruptions. Chirchir assured that sections between Rironi and Naivasha would open before the festive season, and the first Dense Bituminous Macadam layer was laid at Lari, marking a milestone.

However, the highway's political significance is heightened by the regions it connects, including Nairobi, Kiambu, Nakuru, and the Rift Valley, catering to Western Kenya and neighboring countries. For Ruto, completing the highway before the election offers a chance to showcase his infrastructure achievements in politically crucial areas.

The project's economic implications are also under the spotlight, particularly the planned Ksh8 per kilometre toll charges, which have sparked opposition from motorists who argue for exemptions or toll-free alternatives. The Kenya Motorists Association has even challenged the tolling arrangement in court. Additionally, financial concerns have arisen, with potential liabilities of Ksh180.73 billion if the project's current 30-year concession agreements are terminated.

These liabilities, stemming from the government's reliance on taxpayers, echo past controversies involving concession agreements, such as the cancelled French-backed project. The government's reliance on Chinese contractors, including China Road and Bridge Corporation, adds another layer to the project's complexity. As the election approaches, the highway's real test will be its impact on road travel, safety, and affordability, rather than mere announcements and milestones.
