In a notice issued on Friday, February 13, KeNHA stated that several sections between the James Gichuru junction and Rironi will be shut temporarily.
The closures, according to the agency, are meant to allow construction works under the expansive Rironi-Mau Summit superhighway project.
“KeNHA notifies the public that a section of A8 Road (James Gichuru Junction-Rironi Highway) will experience temporary lane closures from Friday, February 20, 2026, to Saturday, April 4, 2026, inclusive. The closure is to facilitate the surface dressing works along this road section,” the advisory read in part.
KeNHA added that alternative routes will be provided to ease traffic flow in the affected areas.
The remedy includes diversion to untouched lanes and use of service one.
“The works will be implemented in phases, during which traffic will be diverted to the remaining lanes or to the service roads where available,” KeNHA said.
Motorists using the road were counselled to adhere to the directives on site and to cooperate with traffic police and marshals stationed along the route.
KeNHA further advised drivers to approach construction zones cautiously and follow the designated diversion routes.
Earlier, Transport Cabinet Secretary Davis Chirchir announced that the stretch between Rironi and Naivasha will be completed by August 2026.
The dualling of the Nairobi-Nakuru Highway was launched last November by President William Ruto.
The president remarked that the launch was long overdue, noting that the project would ease traffic congestion along the major route.
He assured the public that with construction already underway, traffic flow is expected to improve by late next year.
Ruto emphasised that this festive season would be the last in which travellers endure gridlock, pointing out that although the road will not be fully completed by the end of next year, the most critical sections will be finished.
The project is scheduled for full completion by June 2027.
Ruto explained that the only year motorists would continue to face the familiar heavy traffic, long jams, and delays during the festive season is this one.
By December next year, he said, the road will be clear, with critical sections already completed, and by June 2027 the entire project will be finalized, bringing an end to congestion, accidents, and wasted travel time.
He launched the dualling works on November 28 after consultations with senior officials from China Communications Construction Company (CCCC).
Its subsidiary, China Road and Bridge Corporation (CRBC), was contracted to carry out the project.
Ruto added that the key sections of the highway most prone to congestion will undergo expansion simultaneously.
