A section of Ng'ong, Lang'ata and Mombasa roads will remain closed for at least 12 hours on Sunday, October 30, to pave way for the Stanchart Marathon.
Speaking during a presser on Tuesday, October 25, Nairobi Traffic Police officer Mary Kiarie confirmed that the roads connecting to the Southern bypass would not be accessible from 12 am.
Affected roads include the section of Mombasa Road connecting the inland container depot (ICD) to the bypass at Ole Sereni.
Motorists plying the Lang'ata Road will experience disruptions in traffic in the area around Uhuru Gardens where the races will be flagged off from.
In addition, they will be unable to use the roadway to Ngong or Mombasa road and have been asked to use alternative routes.
Other affected roads include Karen-Kikuyu, Karen-Mombasa Road, Lang'ata-Kikuyu, Galleria - Kikuyu, Lenana-Kikuyu and Mombasa Road- Ole Sereni.
According to officer Kiarie, motorists would resume using the roads at 1.30 p.m when the event will be concluded.
Traffic police officers and marshalls will be dispatched to the roads to ensure the free flow of traffic during the 12-hour period.
The Stanchart Marathon will see Kenyans participate in several races including the 5,000m, 10,000m and half-marathons.
The event has attracted athletes locally and internationally and will culminate in the 42-kilometre race for men and women categories.
Kenyans unable to physically participate in the races can take part in a five-day virtual race between Monday, October 24, and Saturday, October 29.
