KeNHA announces temporary traffic disruption on Emali–Isineti Road
17th July, 2026 01:35 PM
The Kenya National Highways Authority (KeNHA) has announced a temporary traffic disruption along a section of the Emali–Isineti (A5) Road near Simba Cement to pave the way for drainage improvement works.
In a public notice issued on July 17, 2026, the authority said the affected section will be partially closed from Friday, July 24, to Thursday, August 13, 2026. The temporary measures are expected to allow construction works to continue while keeping traffic moving along the busy road corridor.
Drainage works
The authority explained that the closure is necessary to facilitate the installation of a culvert across the carriageway at an existing natural water channel. The drainage structure is expected to improve water flow and help protect the road from damage caused by heavy rainfall.
“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,” KeNHA stated.
Once completed, the works are expected to improve the durability of the road while reducing the risk of flooding that could interfere with traffic movement during rainy seasons.
Temporary diversion
To minimise disruption during construction, KeNHA noted that motorists will be redirected through a temporary diversion built alongside the affected section of the road. The diversion will be approximately 100 metres long and will allow vehicles to continue using the route throughout the project.
“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,” the authority said.
The single-lane arrangement means motorists travelling in opposite directions will use the diversion alternately, and drivers should expect occasional delays, particularly during busy travel periods.
Caution
The authority has advised all road users to remain alert while approaching the construction zone and to observe the temporary traffic management measures that will be put in place throughout the project.
“Motorists are, therefore, advised to exercise caution, adhere to traffic signs, and cooperate with the police officers and traffic marshals on site,” KeNHA said.
Traffic marshals and police officers will be deployed to guide motorists through the diversion and help maintain the smooth flow of traffic while ensuring the safety of both road users and construction workers.
The temporary disruption is expected to remain in place until August 13, 2026, after which normal traffic flow will resume once the drainage works have been completed.
