Chirchir said on Wednesday that construction of the dual carriageway was progressing well, with motorists expected to start using the upgraded section once the works are completed.
“By October 30, from Rironi to Naivasha, we will have completed the dualling and opened the road to traffic,” Chirchir said.
The announcement offers a fresh timeline for motorists who have endured persistent congestion, particularly along the steep escarpment and other bottlenecks on the busy Northern Corridor.
📌 What You Need to Know
The Rironi-Mau Summit project was officially launched by President William Ruto at Kamandura, Kiambu County, in November 2025. The first phase covers the Rironi-Naivasha-Gilgil corridor and the Rironi-Maai Mahiu-Naivasha route.
The project is being implemented under a Public-Private Partnership (PPP) arrangement involving China Road and Bridge Corporation (CRBC) and the National Social Security Fund (NSSF). The first phase covers about 139 kilometres and is being delivered under a design, finance, build, operate, maintain and transfer model.
The broader project is intended to transform one of Kenya’s busiest transport corridors, which forms part of the Northern Corridor linking the Port of Mombasa to Uganda and other markets in East and Central Africa.
Chirchir said construction would continue beyond Naivasha, with the government turning its attention to the Naivasha-Nakuru section and the escarpment section beginning at Kamandura.
“We will then continue constructing the Naivasha-Nakuru section, as well as the escarpment section from Kamandura,” he said.
Construction is already under way at several points along the corridor. Contractors have been undertaking earthworks, widening the existing road and carrying out drainage and other preparatory works as new sections of the dual carriageway take shape.
