The Nakuru-Nairobi highway was on Friday evening closed after an oil tanker spilled fuel on the road following an accident.
The Kenya National Highways Authority (KeNHA) said that the accident occurred at Kikopey after the tanker lost control and overturned, spilling the oil on the road.
The spilled oil made the road surface slippery and unsafe for use by motorists.
“This has caused a traffic snarl up along the Gilgil-Nakuru road section,” KeNHA said in a tweet.
