The Kenya National Highways Authority (KeNHA) has restored traffic along the Mai Mahiu–Suswa–Narok (B7) highway after several days of closure caused by flooding and heavy silt that had blocked sections of the road near Suswa.
The authority confirmed on March 13 that the affected stretch has been cleared and is now accessible to motorists following urgent clean-up works carried out after floodwaters deposited large amounts of soil and debris at Kedong Ranch.
“The Kenya National Highways Authority (KeNHA) is pleased to inform the public that the Mai Mahiu - Suswa - Narok (B7) Road is now open to traffic. This follows the closure of the road section on 7th March, 2026, due to flooding and deposition of silt at Kedong Ranch near Suswa,” stated KeNHA.
The highway had been shut on March 7 after flooding and thick layers of silt covered parts of the road, making it unsafe for vehicles to pass through the area.
The B7 route is an important road connecting Nairobi with Narok and other parts of the South Rift region, carrying a steady flow of passenger vehicles and trucks transporting goods.
KeNHA said response teams moved quickly to remove the silt and other materials that had accumulated on the road, allowing normal traffic to resume once the area was cleared.
At the time the closure was announced, motorists were directed to use alternative roads to avoid the blocked section. Drivers travelling between the regions were advised to use the Narok-Mau Narok-Nakuru (B18) road or the Ngong-Suswa road as crews worked to reopen the highway.
Even after restoring traffic flow, the authority is asking drivers to remain alert when travelling along parts of the route due to the ongoing rainy conditions.
“The Authority, however, appeals to motorists to exercise caution when driving through the sections of this road as the rains continue, particularly between Naivasha ICD (Km 14) and Suswa Ranch (Km 39),” advised the notice.
Recent rainfall has caused damage to several road structures across the country, leading to closures and disruptions in different regions.
In recent weeks, heavy rains forced the shutdown of key bridges including the Migori River Bridge in Migori County, the Mogor Bridge in Narok County and the Kipsonoi River Bridge in Bomet County after they were affected by flood damage.
Other transport routes have also faced challenges. Floodwaters cut off the Madogo-Garissa Road near Kona Punda, while in Nairobi a section of the Muthaiga-Kiambu (B32) road collapsed, disrupting movement between Fourways Junction and St Mary’s School-Runda.
The reopening of the Mai Mahiu–Suswa–Narok road comes as the Kenya Meteorological Department warns that heavy rainfall is expected to return across many parts of the country this weekend after a break that lasted about five days.
Transport authorities are urging road users to remain careful while travelling, especially in areas prone to flooding or road damage during the rainy season.
KeNHA says it continues to monitor road conditions across the country as it works to keep the transport network open and support the movement of people, goods and services that are important for economic activity.
