The Kenya National Highways Authority (KeNHA) has warned motorists to exercise extreme caution or seek alternative routes after heavy rainfall triggered flooding and significant silt accumulation along sections of the Mai Mahiu–Suswa–Narok (B7) Road.
In an advisory issued on Thursday evening, April 16, 2026, KeNHA said parts of the highway at Kedong Ranch near Suswa had been severely affected by floodwaters and heavy silt deposits following sustained rains in the area.
The agency noted that emergency teams are working around the clock to clear the debris and restore traffic flow. However, motorists have been cautioned against attempting to drive through flooded sections, citing the risk of vehicles being swept away or getting stuck in deep silt.
KeNHA identified the stretch between Naivasha Inland Container Depot (ICD) at kilometre 14 and Suswa Ranch at kilometre 39 as particularly hazardous, urging drivers to proceed with extreme care.
Motorists have been advised to use the Narok–Njoro–Nakuru (B18) Road as a safer alternative route.
The Mai Mahiu–Suswa–Narok corridor has experienced similar disruptions in recent months, including incidents reported in March 2026 that led to temporary closures and clean-up operations.
The B7 highway is a critical transport link connecting Nairobi to the Maasai Mara and the wider South Rift region. Disruptions along this route often have a significant impact on commuters, transporters, and the tourism sector.
KeNHA has assured the public of its commitment to restoring normal traffic flow as quickly as possible, while prioritising the safety of all road users.
