The Kenya National Highways Authority has announced the temporary closure of a section of the Isiolo–Kirish (A2) road near the School of Military Engineering access road to allow for reconstruction works.
KeNHA said the affected stretch at Km 29+140 will remain closed from April 17 to May 15, 2026.
According to the authority, the closure is necessary to facilitate the reconstruction of a failed road pavement between Km 29+140 and Km 29+300.
Motorists have been advised to use designated diversion routes as outlined in the traffic management plan and to cooperate with police officers and traffic marshals stationed at the site.
The agency said the works are aimed at improving road safety and ensuring smoother traffic flow along the key transport corridor linking Isiolo to northern Kenya.
KeNHA Director General Luka Kimeli urged road users to exercise patience during the construction period, noting that the temporary inconvenience will result in long-term benefits once the repairs are complete.
The Isiolo–Kirish road forms part of the A2 highway, a critical route for movement of goods and passengers in the region.
The Kenya National Highways Authority (KeNHA) is a statutory body established under the Kenya Roads Act of 2007 and inaugurated in September 2008.
