KeNHA Announces Temporary Closure of Section of Nairobi Southern Bypass for Marathon
The Kenya National Highways Authority (KeNHA) has issued a public notice informing motorists of a temporary closure along a section of the Nairobi Southern Bypass. The affected stretch runs between Ole Sereni Interchange and Lang’ata Road Interchange.
The closure is scheduled to take place on Sunday, May 10, 2026. According to the notice, the road will be inaccessible from 6:00 a.m. to 1:00 p.m. during this period.
The authority has stated that the measure is necessary to facilitate the smooth running of the 2026 Nairobi Marathon event.
Road Closure to Affect Key Traffic Corridor
The temporary shutdown of this section is expected to disrupt normal traffic flow for several hours.
KeNHA has emphasized that the closure is limited strictly to the specified timeframe and stretch of the bypass. Motorists planning to use this route during the affected hours are advised to make alternative travel arrangements in advance to avoid inconvenience.
Alternative Routes Provided
To mitigate disruption, KeNHA has outlined an alternative route for affected motorists. Drivers are advised to use Mombasa Road (A8) Highway from Ole Sereni Interchange. From there, they should proceed to the Nyayo National Stadium Roundabout in order to access Lang’ata Road.
This diversion is expected to accommodate traffic that would otherwise rely on the closed section of the bypass. However, motorists are encouraged to anticipate possible congestion along the alternative route due to increased traffic volume.
Call for Cooperation with Traffic Authorities
The authority has stressed the importance of compliance with traffic directives to maintain order and minimize delays. Motorists are also encouraged to exercise patience and adhere to all road safety measures during this period.
The temporary closure forms part of logistical arrangements for the Nairobi Marathon, which requires controlled road access to ensure participant safety and event coordination.
