The Kenya National Highways Authority (KeNHA) has warned of a traffic congestion along the Rironi-Nakuru -Mau Summit Road for the whole day on Friday, November 28, 2025.
The traffic jam, KeNHA said, will be as a result of the planned launch of dualling of the road by President William Ruto.
According to KeNHA, the launch will be at various locations along the road.

“The road is envisaged to have significant traffic congestion for the whole day,” the agency said.
“Consequently, the authority advises motorists intending to use this road to either reschedule their travel or use alternative routes,” it added.
What are alternatives routes for Rironi-Nakuru -Mau Summit Road?
KeNHA has provided up to four alternative routes provided to the Rironi-Nakuru -Mau Summit Road.
They are:
- Ngong – Suswa – Narok – Mau Narok – Njoro – Nakuru
- Nairobi – Thika – Magumu – Njabini – Ol Kalou – Nakuru
