The Kenya National Highways Authority (KeNHA) has announced a two-week partial closure of a key section of the Mombasa-Nairobi Highway from Saturday, August 23.
In a notice issued on Tuesday, August 19, the Authority revealed the affected stretch will be from the vital Makupa Bridge to the Changamwe Interchange in Mombasa County.
According to the Authority's Director General, Luka Kimeli, the closure of the vital corridor was to allow for road construction and drainage works.
"The Kenya National Highways Authority (KeNHA) wishes to notify the public that a section of the Mombasa-Nairobi (A8) Highway will experience traffic disruption between the Makupa Bridge and Changamwe Interchange from Saturday, August 23, 2025, to Sunday, September 7, 2025," KeNHA said in a statement.
To manage traffic and ensure minimal disruption to the flow of vehicles along the busy stretch, the Authority issued a traffic management plan which will require motorists to share a section of the Nairobi-bound road.
This effectively means that both directions of the traffic will operate on one carriageway for six kilometres for the next two weeks.
The move will likely result in slowed movement, with road users being advised to exercise patience and plan their travel accordingly while following directions issued by police officers and traffic marshals on site.
Notably, the Makupa-Changamwe section is one of the busiest segments in the coastal region, as it serves as a key artery for traffic flowing in and out of the Port of Mombasa.
The Makupa bridge -Changamwe Interchange drainage construction works began in November 2024, and at the time, KeNHA announced a similar traffic disruption.
Since the roadworks began, however, the Authority has had to consistently embark on maintenance works to avert the risk of flooding.
In recent months, KeNHA has taken to modernising the Nairobi-Mombasa highway in different forms, including improving drainage infrastructure to handle heavy rains and avert the risk of flooding.
Nairobi has also seen several traffic disruptions from KeNHA, mostly affecting the Nairobi-Mombasa highway. One of the latest closures saw a section of Mombasa Road between General Motors Roundabout and the Southern Bypass Interchange.
In July, a section of Mombasa Road near Syokimau was also closed, affecting motorists travelling to Mlolongo and Katani.
