Motorists are still stuck in a heavy traffic jam along the Nakuru-Nairobi highway since Saturday.
Those driving on the route were forced to spend the night on the road, including Safari Rally fans traveling from Sleepy Warriors where the day's racing was taking place.
Commenting on the snarl-up, Gilgil Police boss Francis Tumbo said the jam was caused when about 2,000 motorists driving the fans joined the highway.
"The traffic is heavy but it's moving and police are on the highway to ensure that there is no unnecessary congestion," he said.
Taking to Twitter, Kenyans have called for the expansion of the road to avoid a repeat of the scene.
"The expansion of Nairobi -Nakuru highway is long overdue. My mom and aunts just spent the night here cold and hungry!" a user Brenda Kiarie said.
"More reasons why that Nairobi Nakuru/Kisumu highway should be dual-carriageway,"Timoshenko Kiptoo tweeted.
"Current situation in Naivasha. To those in Kisumu, better use the Narok way to Navigate to Nairobi. Things are tough here. Nakuru Nairobi highway should be considered for expansion to avoid this in the near future,"Dollar Nagafwa said.
