KeNHA Issues Advisory as Floods, Silt Slow Traffic near Suswa
Earlier, the Kenya National Highways Authority (KeNHA) warned motorists of severe travel disruptions along the Mai Mahiu–Suswa–Narok (B7) Road due to heavy rains that have caused flooding and silt deposits.
The most affected stretch was at Kedong Ranch near Suswa, where water levels made driving dangerous and slowed traffic.
KeNHA urged drivers not to ignore safety instructions, as navigating flooded sections or silted areas could result in vehicles being stranded or swept away.
“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),”

Additionally, the authority advised travellers who had not yet started their journeys to postpone their trips until the floodwaters recede.
However, those who had to travel could use alternative routes, including Ngong–Suswa, Nairobi–Naivasha–Nakuru–Mau Narok–Narok, and Nairobi–Naivasha–Longonot–Suswa.
Reassuring road users, the Authority said it is working to clear the affected areas and secure safe travel.
