Motorists warned of traffic disruptions on 5 major roads in Nairobi
Motorists have been warned of expected traffic disruptions on major roads in Nairobi ahead of the Mater Heart Run 2025.
In a traffic advisory issued on Saturday, May 31, 2025, the hospital stated that the affected roads include City Hall Way, Uhuru Highway, Haile Selassie Avenue, Bunyala Road, Upper Hill Road, Elgon Road, and Ngong Road.
Furthermore, the advisory stated that congestion is expected near KICC, Bunge, and Britam Tower, with potential spillover into nearby roads, such as Kenyatta Avenue, during the run from 7:00 am to 11:00 am.
The hospital has also advised motorists to find alternative routes and, if possible, to travel after 5:00 pm.
“Bypass the area by using Waiyaki Way (westbound) or Mombasa Road (southbound). If heading into the city centre, consider using Lang’ata Road as a detour,” read the advisory.
“If possible, travel after 05.00 pm when the event ends.”

Traffic disruption is also expected to affect roads in Mombasa, Kericho, Nakuru, Nyeri, Bomet, Kisumu, Kakamega, Machakos, and Uasin Gishu.
The runs will start simultaneously at Loreto Convent Mombasa, Kericho Teachers’ College, Nakuru Athletics Club, Dedan Kimathi University of Technology, St. Mary’s Day & Boarding Primary School, Jaramogi Oginga Odinga Sports Ground, Bishop Sulumeti Girls, The Machakos School, and Moi Girl’s Eldoret.
The Mater Heart Run was started in 1995 as one of the main fundraising avenues for the Mater Cardiac programme and was initially held only in Nairobi. It has grown over the years and is now held in a total of ten counties.
Nairobi Expressway
This comes after motorists using the Nairobi Expressway braced for delays as the Museum Hill Exit A was temporarily closed to allow for construction and maintenance work.
The exit is a key access point connecting central Nairobi to the elevated toll road, and the closure is expected to cause traffic snarl-ups in the area.
In a notice issued by Moja Expressway Company on May 10, 2025, the operator of the 27-kilometre motorway, motorists were urged to “plan their trips accordingly or use alternative routes such as the Haile Selassie Exit.
“This is part of our broader commitment to improve the expressway experience and ease traffic congestion,” the statement read in part.
The Museum Hill Exit A, which currently features three lanes, is poised for expansion to five lanes, an initiative first announced in December 2023 by then-Transport Cabinet Secretary Kipchumba Murkomen. However, the project has faced delays due to ongoing negotiations with the University of Nairobi regarding land acquisition.
