Kenya, 24 January 2026 - The Kenya National Highways Authority (KeNHA) on Saturday temporarily closed the Nairobi Southern Bypass in the Mombasa Road-bound direction following a serious fire incident involving two fuel tankers.
According to an emergency traffic alert issued by KeNHA, the accident resulted in one of the oil tankers falling from the elevated section of the Southern Bypass onto the lower road.
The tanker subsequently burst into flames, triggering a significant fire outbreak with a high risk of explosion.
The authority stated that the closure was necessary to facilitate emergency response operations and to protect public safety.
Fire and emergency services are currently on site, working to contain the blaze and manage the hazardous situation.
Traffic police have secured the area to prevent unauthorised access and to manage traffic flow around the incident.
KeNHA advised motorists to avoid the Southern Bypass until further notice.
Road users intending to access Mombasa Road are recommended to divert via Lang'ata Road.
Motorists should prepare for traffic delays on alternative routes due to the increased volume of vehicles.
The public has been strongly cautioned against approaching the incident scene.
