KeNHA Director-General Kungu Ndung’u urged motorists to be patient, maintain lane discipline and consider alternative routes to ease congestion and enhance road safety.
Motorists using the Nakuru-Nairobi highway on Friday endured hours of gridlock due to heavy traffic caused by increased festive season travels.
In a statement, the Kenya National Highway Authority (KeNHA) said there was significant congestion on the Rironi-Naivasha-Nakuru road and the Rironi-Mai Mahiu-Naivasha section.
