Part of Bomas–Kiserian Road to experience traffic disruption until December – KeNHA
By Kenneth Mwenda, October 21, 2025Motorists using the Bomas–Kiserian (B19) Road should expect traffic disruption for over a month following the extension of a temporary road closure announced by the Kenya National Highways Authority (KeNHA).
In a public notice dated October 16, 2025, KeNHA said the closure affects the section between Brookhouse/Galleria (Km 0+500) and the Catholic University of Eastern Africa junction (Km 1+000). The disruption will run from Monday, October 20, 2025, to Monday, December 1, 2025.
KeNHA explained that the closure is necessary to allow for the construction of two box culverts along the affected section. The works are part of ongoing efforts to improve drainage and road safety on the Bomas–Kiserian corridor, a key link for traffic moving between Nairobi and Kajiado County.
“KeNHA wishes to inform the public of a temporary traffic disruption due to the closure of the Bomas–Kiserian (B19) Road from the section after Brookhouse/Galleria (Km 0+500) to the section after Catholic University of Eastern Africa junction (Km 1+000),” the agency stated.
Alternative routes for Magadi Road
The notice further advised motorists to use alternative routes during the period. These include Lang’ata Road–Lang’ata South Road–Kiboko Road–Banda Lane–Magadi Road, or Lang’ata Road–Lang’ata South Road–Kiboko Road–Mukoma Road–Magadi Road near Shell Petrol Station.
Acting Director General Eng. Luka Kimeli said a traffic management plan has been put in place to guide motorists through the diversion.
“KeNHA advises motorists to follow the traffic diversion plan, project road signs, and cooperate with police and traffic marshals on site,” he said.
The roadworks come as part of broader maintenance and safety improvement projects being undertaken across the Nairobi Metropolitan region. Earlier this month, KeNHA also announced a two-month disruption on Thika Superhighway at Kihunguro.
The disruption will allow for the construction of column bases and stub columns for the new Kihunguro footbridge. The project is part of KeNHA’s ongoing effort to improve pedestrian safety and ease movement along the busy superhighway.
