The Kenya National Highways Authority (KeNHA) on August 22 announced a temporary closure of Bomas – Kiserian (B19) Road to allow for construction works that will last nearly two months.
“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,” read part of the KeNHA notice.

The closure will take effect from Thursday, 28th August 2025, and remain in place until Monday, 20th October 2025.
KeNHA explained that the disruption is necessary to facilitate the construction of two box culverts along the road.
“This is due to scheduled roadworks for the construction of the 2No. Box Culverts on the road section,” KeNHA confirmed.

The authority advised motorists to use designated alternative routes during the period of the closure.
The recommended diversions include:
