NPS Announces Southern Bypass Closure for Nairobi Marathon, Issues Traffic Diversions
In a traffic advisory issued on Saturday, police said the Southern Bypass would be completely closed from midnight on Saturday, October 24, until 3pm on Sunday, October 25, 2026.
Nairobi's National Police Service (NPS) has announced a temporary closure of the Southern Bypass and additional traffic restrictions on Lang’ata Road and Ngong Road for the duration of the Standard Chartered Nairobi Marathon, which will take place from October 24 to October 25, 2026. The closure will commence at midnight on Saturday, with the affected section stretching from Ole Sereni Interchange to Kikuyu Town, impacting motorists traveling between Mombasa Road, Lang’ata, Karen, and areas west of Nairobi.
Additionally, partial closures and security measures will impact select parts of Lang’ata Road and Ngong Road near Uhuru Gardens and Nairobi National Park, where marathon activities will be held.
To mitigate congestion, the NPS has issued traffic diversions, urging motorists to utilize alternative routes. Vehicles approaching from Mombasa Road and the Inland Container Depot are advised to use Mombasa Road and Uhuru Highway leading to the Central Business District (CBD). Those traveling from Western Kenya via the Kikuyu Bypass should take James Gichuru Road or Waiyaki Way, depending on their intended destinations.
Motorists entering from Lang’ata and Karen are instructed to use Lang’ata Road, Dagoretti Road, and Ngong Road as alternatives, depending on their specific locations. Drivers coming from the Lenana area along Ngong Road should opt for Waiyaki Way via Naivasha Road or James Gichuru Road, while those heading towards Mombasa Road should utilize Lang’ata Road via Karen Road.
The NPS is collaborating with relevant agencies to ensure smooth traffic management throughout the marathon. Motorists are strongly advised to demonstrate patience, adhere to traffic regulations, and follow the instructions of police officers and marshals stationed along the affected routes. Violations of traffic rules during this period may result in severe consequences.
The marathon, known for its participation of runners and spectators, necessitates temporary traffic arrangements to accommodate participants and maintain public safety. Motorists are cautioned to allocate extra travel time, obey road signs, and verify their routes prior to embarking on their journeys on Sunday.
