The Kenya National Highways Authority (KeNHA) has announced the reopening of the Mai Mahiu–Suswa–Narok road to traffic following days of closure caused by flooding and silt deposition.
In a notice issued on March 13, KeNHA said the road section that had been closed earlier this month has been reopened following emergency works to clear the debris and restore movement along the key transport corridor.
“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 March 7, 2026, due to flooding and deposition of silt at Kedong Ranch near Suswa,” stated KeNHA.
The route had been shut on March 7 after floodwaters and large amounts of silt covered sections of the highway at Kedong Ranch, cutting off traffic along the busy road that links Nairobi to Narok and the wider South Rift region.
KeNHA said its emergency teams worked to remove the accumulated debris and clear the affected sections, allowing traffic to resume along the strategic B7 road that carries vehicles transporting goods and passengers daily.
When the closure was announced earlier, motorists were advised to seek alternative routes while the clean-up exercise continued. The Authority had directed drivers to use the Narok-Mau Narok-Nakuru (B18) road or the Ngong-Suswa road as crews worked to restore the blocked section.
Even with the road now reopened, KeNHA has warned motorists to remain careful while driving through parts of the route due to ongoing rains.
“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.
