The Kenya National Highways Authority (KeNHA) has issued an urgent travel advisory following the heavy rainfall that was witnessed on the evening of Thursday, March 19, 2026.
In an advisory shared via social media at night, the authority warned that flooding and heavy silt deposits had disrupted a key section of the Mai Mahiu–Suswa–Narok (B7) Road.
KeNHA said the affected section lies at Kedong Ranch near Suswa, where rising floodwaters and debris have made the road unsafe for motorists.
“The Kenya National Highways Authority (KeNHA) wishes to notify motorists that this evening the Mai Mahiu-Suswa-Narok (B7) Road experienced flooding and silt deposition at Kedong Ranch near Suswa. The Authority is currently working to reopen the affected section of the road,” KeNHA stated.
The authority confirmed that emergency teams have been deployed and are working to clear the silt and restore normal traffic flow.
“Motorists are advised to avoid driving through flooded areas and to strictly follow instructions from the police and traffic marshals to prevent being swept away or getting stuck in silt deposits,” the agency said.
The disruption comes amid ongoing heavy rains pounding parts of the country, with KeNHA warning that conditions remain dangerous, particularly along the stretch between Naivasha Inland Container Depot (Km 14) and Suswa Ranch (Km 39).
Drivers who have not yet begun their journeys have been urged to delay travel until the floodwaters subside.
For those with unavoidable trips, the authority has recommended alternative routes, including Ngong – Suswa, Nairobi – Naivasha – Nakuru – Mau Narok – Narok, and Nairobi – Naivasha – Longonot – Suswa.
KeNHA Director General Luka Kimeli also assured road users that the authority is working around the clock to ensure safety and reopen the road as soon as possible.
“KeNHA assures all road users that it is working around the clock to restore normal traffic flow and ensure the safety of motorists,” the statement read.
