The Kenya National Highways Authority (KeNHA) has extended the closure of a section of the Bomas-Kiserian (B19) for 42 days.
In a statement on Thursday, October 17, KeNHA said the section of the Bomas-Kiserian road between Galleria to after the Catholic University of Eastern Africa junction will remain closed from Monday, October 20 to Monday, December 1, 2025.
The authority noted that the closure is due construction of two box culverts along the affected stretch.
“The Kenya National Highways Authority (KeNHA) would like 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).
“This is due to scheduled roadworks for the construction of the 2No. Box Culverts on the road section from Monday, 20th October 2025, to Monday, 1st December 2025,” KeNHA stated.

The construction is part of infrastructure improvements to enhance road safety and connectivity.
The authority advised motorists to use the Langata Road - Langata South Road - Kiboko Road - Banda Lane - Magadi Road to get to their destinations.
Alternatively, motorists can use the Langata Road - Langata South Road - Kiboko Road - Mukoma Road - Magadi Road (near Shell Petrol Station).
“KeNHA advises motorists to follow the traffic diversion plan, project road signs, and cooperate with police and traffic marshals on site,” the authority added.
KeNHA had announced on August 22 the closure of the section from Thursday, August 29, 2025, to Monday, October 20, 2025.
The extension of the closure was prompted by delays in completing the construction of the two box culverts within the timeline.
This comes days after KeNHA announced a 2-month-long traffic disruption along a section of the Thika Superhighway.
In a notice shared on October 13, KeNHA informed the public that a section of the Thika Superhighway (A2 Road) at Kihunguro will experience traffic disruption along both the Nairobi and Thika-bound service lanes from Monday, October 20, 2025, to Saturday, December 20, 2025.
The authority explained that the disruption is necessary to construct the Kihunguro footbridge column bases and stub columns at the section.
