The Kenya National Highways Authority (KeNHA) has issued a traffic advisory following flooding and silt deposition along the Mai Mahiu–Suswa–Narok (B7) Road, warning motorists to exercise extreme caution.

In a statement dated March 19, 2026, KeNHA said the affected section is at Kedong Ranch near Suswa, where heavy rainfall has disrupted normal traffic flow.

“The Mai Mahiu–Suswa–Narok (B7) Road experienced flooding and silt deposition at Kedong Ranch near Suswa,” the authority said, adding that efforts are underway to reopen the road.

“The Authority is currently working to reopen the affected section of the road.”

Motorists have been advised to avoid driving through flooded areas and to strictly follow instructions from police and traffic marshals to prevent accidents. KeNHA warned that drivers risk being swept away or getting stuck in silt deposits if they ignore safety guidance.

“As the area continues to receive heavy rainfall, motorists are further urged to exercise extreme caution when driving along various sections of the road, particularly between Naivasha ICD (Km 14) and Suswa Ranch (Km 39),” the statement said.

The agency also urged travelers who have not yet begun their journeys to delay travel plans until floodwaters subside. For those who must travel, KeNHA recommended alternative routes including Ngong–Suswa, Nairobi–Naivasha–Nakuru–Mau Narok–Narok, and Nairobi–Naivasha–Longonot–Suswa.

KeNHA assured road users that it is working around the clock to restore normal traffic flow and ensure safety.
