Motorists using the busy Nairobi–Mai Mahiu Road have been warned to expect traffic disruption after an oversized load forced the shutdown of an entire lane.
According to a notice from the Motorist Association of Kenya, the load caused delays along the route and forced traffic diversions.
Further, the traffic advisory issued at around 8:00 AM explained that the wide load covered the full width of one side of the road, leaving no space for oncoming vehicles to pass.
Consequently, the road became impassable in certain sections, especially for those heading towards Nairobi from Mai Mahiu.
“Be informed that there is a total lane shutdown along Nairobi–Mai Mahiu Road due to a wide load that covers the width of the road, with no space allowing oncoming vehicles to pass,” the advisory read in part.

Motorists Warned to Avoid Nairobi–Mai Mahiu and Use Alternative Routes
Motorists plying the route have been advised to use alternative routes.
Moreover, traffic officers have been deployed to the area to manage the situation and guide road users. Drivers have urged to adhere to instructions and remain cautious, as the disruption is expected to last until the load is safely cleared or rerouted.
“All motorists from Mai Mahiu are advised to use alternative routes, like the Mai Mahiu–Kijabe Road. Officers are on the ground monitoring the situation,” added the statement.
The transport of such wide loads is typically done under special clearance.
Motorists are advised to stay informed through official channels and consider delaying travel along the affected stretch if possible.

Earlier Alert on Traffic Disruption
The Kenya National Highways Authority (KeNHA) temporarily closed a section of the Nairobi Southern Bypass to facilitate critical infrastructure monitoring, according to a public notice dated June 1, 2025.
KeNHA announced that the closure affected a stretch near the entrance of the CRBC Camp, opposite Nairobi National Park.
The partial shutdown began at 10:00 PM on Saturday, June 7, and ended at 6:00 AM on Sunday, June 8.
Further, the authority noted that the disruption allowed for the installation of stress-strain sensors on the highway pavement that were part of a project to assess the mechanical behaviour of the road, record traffic volumes, monitor axle load data, and predict the pavement’s service life.
KeNHA assured road users that the closure was temporary and aimed at improving long-term road safety and maintenance.
