Kenya National Highways Authority (KeNHA) has announced the temporary closure of a section of the Mombasa-Nairobi Highway to facilitate ongoing construction and drainage works.
In a notice issued on Tuesday, September 23, the Authority extended the temporary closure of the highway section between Makupa Bridge and Changamwe Interchange. The restriction is now set to run from Tuesday, September 23, 2025, to Saturday, October 4, 2025.
"KeNHA wishes to notify the public of the extension on the temporary closure of Mombasa – Nairobi (A8) Highway between Makupa Bridge and Changamwe Interchange from Tuesday, September 23, 202,5, to Saturday, October 4, 2025, to allow for road construction and drainage works to ensure seamless road connectivity along this section," the Authority stated.
The Authority has advised motorists to follow the proposed traffic management plan and cooperate with police and traffic marshals deployed on site to ensure the smooth flow of vehicles during the closure period.

KeNHA emphasized that the temporary closure is essential for comprehensive road construction and drainage works to ensure seamless road connectivity between the Makupa Bridge and Changamwe areas.
This latest closure represents an extension of earlier restrictions on the same highway section. In August, KeNHA had initially announced a two-week partial closure of the stretch from Saturday, August 23, affecting the same vital corridor between Makupa Bridge and Changamwe Interchange in Mombasa County.
The August closure was also intended to facilitate road construction and drainage works. The Authority's Director General indicated at the time that traffic disruption would last until September 7, 2025.
The Makupa-Changamwe section represents one of the most crucial transportation corridors in the coastal region, serving as a primary gateway for traffic entering and exiting the Port of Mombasa.
The strategic location is vital for commercial and passenger traffic along Kenya's most important highway connection.
