Motorists traveling between Nairobi and the Maasai Mara region are facing major disruptions after heavy overnight rains triggered severe flooding and silt deposition along the Mai Mahiu – Suswa – Narok (B7) Road.
The Kenya National Highways Authority (KeNHA) issued a traffic advisory late Thursday, April 16, warning that several sections of the highway near Kedong Ranch have become impassable. The flooding follows a surge in rainfall that has already caused significant infrastructure damage across 30 counties this season.
Key Impacted Areas
KeNHA has specifically flagged the 25-kilometer stretch between Naivasha Inland Container Depot (Km 14) and Suswa Ranch (Km 39) as particularly hazardous. Motorists are being warned of:
- Massive Silt Deposits: Heavy sediment has washed onto the roadway, creating a risk of vehicles getting stuck.
- Flash Flood Risks: Rapidly rising water levels pose a direct threat of vehicles being swept away.
Response and Alternative Routes
Emergency response teams have been deployed to the affected sections and are working “around the clock” to clear the silt and restore normal traffic flow. In the meantime, KeNHA advises those who have not yet started their journeys to use the Narok – Njoro – Nakuru (B18) Road as an alternative route.
Police officers and traffic marshals are on-site to direct motorists. The Authority has urged all road users to strictly follow these officials’ instructions and exercise “extreme caution” if they must navigate the area.
Regional Weather Outlook
The disruption comes as the Kenya Meteorological Department warns of a late-month surge in the March-April-May “long rains” season. Forecasters expect intensified rainfall and occasional afternoon storms to continue nationwide through the end of April, maintaining a high risk of localized flooding and landslides in the Rift Valley and Central Highlands.
Since early March 2026, flood-related incidents in Kenya have claimed at least 110 lives and displaced nearly 35,000 people
