The Kenya National Highways Authority (KeNHA) has given traders and occupants of structures built along the road reserve of the Nanyuki–Naibor Turnoff–Doldol (B101) Road 30 days to vacate ahead of planned construction works.

In a statement issued on Thursday, September 3, the authority said an enforcement operation conducted the same day identified several structures occupying the designated road reserve without approval.

Those affected have been instructed to remove their businesses and other structures and clear the road reserve within the stipulated period. KeNHA warned that structures that remain in place could be demolished once clearance of the road corridor begins as part of the planned upgrade.

According to the authority, the enforcement action is aimed at securing the road reserve, enhancing safety and ensuring construction work proceeds without unnecessary obstruction.

“Clearing the way for the planned improvement of the Nanyuki – Naibor Turnoff – Doldol (B101) Road, KeNHA undertook an enforcement exercise along the designated road reserve to identify and address encroachments,” the statement read.

KeNHA further explained that, “The exercise involved marking unauthorised structures and issuing formal notices to affected occupants as part of efforts to reclaim the road reserve and safeguard public safety ahead of the planned works.”

The operation comes as preparations continue for the upgrading of the 58-kilometre road to bitumen standards.

KeNHA and the project team also carried out technical and operational assessments as part of preparations for the commencement of construction.

The Ksh5.5 billion project is scheduled to run for 36 months and will involve widening the carriageway, adding shoulders and pedestrian walkways, as well as upgrading sections of the route between Nanyuki and the Naibor turnoff.

The authority had earlier announced that utility relocation would also be required before construction begins. Water pipelines, electricity poles and fibre-optic cables located within the project corridor may have to be moved to facilitate the works.

KeNHA has been working with local leaders, government agencies and technical teams to coordinate the relocation exercise and reduce disruptions during construction.

Once completed, the upgraded road is expected to ease movement for residents, traders, livestock and goods while improving access to markets and essential services across Laikipia North.
