End of Gridlock? Ruto Sets Hard Deadline for Sh170 Billion Highway Dualing

The chronic traffic congestion that has long defined the Northern Corridor is facing a definitive timeline for resolution. President William Ruto has officially launched the expansion of the Rironi-Nakuru-Mau Summit highway, issuing a directive to the project contractors to ensure full completion by June 2027. Speaking during the launch at Kamandura in Kiambu County, the President indicated that the 2027 Madaraka Day celebrations, scheduled for Nakuru, should coincide with the delivery of the upgraded road.

This infrastructure undertaking is being implemented through a Public-Private Partnership involving a consortium of the China Road and Bridge Corporation and the National Social Security Fund. The project cost is estimated at approximately Sh170 billion, representing a significant departure from traditional exchequer-funded road works. By utilizing this model, the government intends to design, finance, and operate the road over a 30-year concession period, during which the private partners will recover their investment through tolling.

The technical scope of the project reflects a substantial upgrade from earlier designs. President Ruto revealed that he had initially rejected a two-lane dualing proposal, noting that it would have reached capacity within a decade. The revised plan now includes a four-lane dual carriageway from Rironi to Naivasha and an expanded six-lane dual carriageway between Naivasha and Nakuru. The sections covering Rironi-Maai Mahiu-Naivasha and Nakuru-Mau Summit will be upgraded to four-lane dual roads to accommodate the daily traffic of over 20,000 vehicles.

The Rironi-Mau Summit road serves as a vital artery for the region, facilitating the movement of goods and passengers between Nairobi and the western parts of Kenya, as well as landlocked neighboring countries. The upgrade is expected to integrate grade-separated interchanges, overpasses, and pedestrian bridges to improve safety and reduce the frequency of accidents on what is currently one of the country's most hazardous routes.

Beyond the immediate Rironi-Mau Summit section, the administration has outlined a broader ten-year transport expansion programme. This plan targets the dualing of 2,500 kilometres of highways and the tarmacking of 28,000 kilometres of roads nationwide. Future phases of the corridor expansion are intended to stretch further west, eventually reaching Kericho, Kisumu, and Eldoret, while extending to the Malaba border.

Construction on the 58-kilometre Rironi-Maai Mahiu-Naivasha stretch is also part of the immediate schedule. This auxiliary route is expected to provide an alternative path for heavy transit vehicles, further decongesting the main highway. The President emphasized that leveraging private capital is necessary to avoid adding to the national debt while still delivering world-class infrastructure capable of supporting a growing economy.

As the project moves into the active construction phase, the focus remains on the June 2027 deadline. If achieved, the timeline will see the completion of one of the most ambitious road projects in East Africa, potentially cutting travel times and logistics costs significantly across the Northern Corridor.
