The Kenya National Highways Authority (KeNHA) has announced a 21-day partial closure of a section of the Emali–Isineti (A5) Road near Simba Cement to allow for the installation of a drainage structure.
In a public notice issued on Friday, the authority said the traffic disruption will run from July 24 to August 13, 2026.
According to KeNHA, the temporary closure is necessary to facilitate the construction of a culvert across the carriageway at an existing natural water channel.
“The Kenya National Highways Authority (KeNHA) wishes to notify the public that a section of the Emali–Isineti (A5) Road, in the vicinity of Simba Cement, will be partially closed to traffic from Friday, 24th July to Thursday, 13th August to facilitate the installation of a drainage structure (culvert) across the carriageway at an existing natural channel,” the notice stated.
Temporary diversion for motorists
During the construction period, motorists will be redirected through a temporary 100-metre diversion built alongside the affected section of the highway.
Traffic will operate on a single lane, with vehicles allowed to pass alternately under the guidance of traffic marshals and police officers.
“During the closure period, traffic will be routed through a temporary diversion, approximately 100 metres in length, constructed alongside the closed section. Traffic will flow on an alternating (single lane) basis as indicated in the diversion plan,” KeNHA said.
The authority urged road users to observe traffic signs, cooperate with officers managing traffic and exercise caution to ensure the safety of both motorists and construction workers.
Similar roadworks underway in Kisumu
The latest announcement comes just days after KeNHA announced another temporary traffic disruption along the Kisumu–Kakamega Highway.
The authority said a section between Mamboleo Junction and Kiboswa will be partially closed for 30 days to facilitate the removal of the Coptic Roundabout, which has been linked to numerous fatal road accidents.
KeNHA Director General Luka Kimeli said the works will involve removing the existing roundabout and reconstructing and realigning the affected section of the highway.
Motorists using both road corridors have been advised to plan their journeys in advance and follow traffic management directions throughout the construction period.
