The Kenya National Highways Authority (KeNHA) has issued a public notice informing motorists of an upcoming traffic disruption along the Nairobi-bound lanes of Mombasa Road (A8) near the Katani Road Junction.
In the notice released on Wednesday, April 30, 2025, the authority announced a two-day closure to facilitate the final stages of installing fabricated footbridge beams.
The affected section of the highway will remain closed from Saturday, May 3, 2025, at 10:00 pm, until Sunday, May 4, 2025, at 6:00 am.
“The Kenya National Highways Authority (KeNHA) wishes to notify the public that a section of Mombasa Road (A8) near Katani Road Junction will experience traffic disruption along the Nairobi-bound lanes from Saturday, 3rd May 2025, at 10:00 pm to Sunday, 4th May 2025, at 6:00 am,” the statement from the authority read in part.
Further, KeNHA clarified that the disruption is necessary to allow for the installation of the final segment of the footbridge beams that have been fabricated for the site.
“This is to allow for installation of the remaining fabricated footbridge beams,” the statement added.
To ensure a smooth diversion, the authority also issued a detailed traffic management map and urged motorists to familiarise themselves with the plan in advance to avoid any inconvenience during the specified period.
Additionally, KeNHA appealed to all road users to cooperate with the traffic police officers and marshals who will be stationed on-site during the closure to assist with traffic management.
“KeNHA advises motorists to follow the proposed traffic management plan below and cooperate with the police and traffic marshals on site,” the authority reiterated.
KeNHA’s traffic management plan
According to KeNHA’s proposed plan, vehicles heading towards Nairobi from the Mlolongo direction are expected to join the service lane near the Mlolongo Weighbridge, which is the section leading to the closed road.
From there, vehicles will be required to use the next flyover to shift to the Mlolongo-bound service lane before rejoining the Nairobi-bound lanes via the flyover near Gateway Mall, just after the Syokimau Airport Road junction.
Third phase of closure
This marks the third phase of scheduled traffic disruption at the same location, following two previous interventions.
The second phase was implemented from Saturday, April 26, 2025, at 10:00 pm, to Sunday, April 27, 2025, at 6:00 am, during which traffic along the Nairobi-bound lanes experienced the most significant impact.
“The Kenya National Highways Authority (KeNHA) wishes to notify the public that a section of Mombasa Road (A8) near Katani Road Junction will experience traffic disruption along the Nairobi-bound lanes from Saturday, 26th April 2025, at 10:00 pm to Sunday, 27th April 2025, at 6:00 am,” the authority stated during the second phase.
The authority emphasised that this disruption was a critical move to facilitate the installation of the remaining footbridge beams along the major highway.
First phase of installation
The first phase of the footbridge installation was undertaken earlier from Saturday, April 19, 2025, at 10:00 pm to Sunday, April 20, 2025, at 6:00 am.
“The Kenya National Highways Authority (KeNHA) wishes to notify the public that a section of Mombasa Road (A8) near Katani Road Junction will experience traffic disruption along the Mombasa-bound lanes from Saturday, 19th April 2025, at 10:00 pm to Sunday, 20th April 2025, at 6:00 am,” KeNHA announced in a previous statement issued on Wednesday, 16th April 2025.
“This is to allow for the installation of the fabricated footbridge beams,” they explained.
This initial phase saw significant traffic congestion, making it the most chaotic of all, prompting KeNHA to call on all motorists and commuters to observe traffic guidelines strictly.
During this period, KeNHA urged road users to follow road signs, listen to instructions issued by traffic officers and marshals, and cooperate fully to ensure smooth vehicular movement and public safety throughout the maintenance works.
They also encouraged all travellers to plan their journeys accordingly and to expect only minimal disruption outside the stated hours of closure.
