Rironi To Gilgil Dual Carriage To Be Complete in 6 Months

In November 2024, President Ruto launched construction of the long awaited Rironi – Mau Summit dual carriageway and promised that it would be complete within 6 months.

President William Ruto launched the Rironi–Mau Summit dual carriageway project in November 2025. The full corridor covers ~233 km, built under a public-private partnership with Chinese-led consortia (CRBC & Shandong Hi-Speed), with NSSF as a key equity partner under a 28-year toll concession. He specifically pledged that the Rironi/Kamandura-to-Gilgil stretch would be done within 6 months of launch.
Cabinet Secretary Davis Chirchir in January 2026 inspected ongoing construction works on the Rironi–Mau Summit Highway, expressing satisfaction with the pace and quality of work on one of Kenya’s most important regional transport corridors
In March 2026, the Ministry of Transport revealed that the contractors of the Rironi-Mau Summit and James Gichuru-Rironi highway projects have already opened several sections of the corridor for initial works.
The second phase of the Rironi-Mau Summit Road was announced to be underway and is set to be completed by May 2027, a significant timeline away from the original 6 months stated.
