KeNHA Advises Motorists to Use 7 Detours as Nairobi–Nakuru Highway Traffic Worsens

    Traffic jam

The Kenya National Highways Authority (KeNHA) has issued a traffic advisory, announcing seven alternative routes for motorists following severe congestion along the busy Nairobi–Nakuru highway.

In a statement released on Wednesday, December 24, the Authority cautioned motorists about increased traffic build-up along the Rironi–Nakuru–Mau Summit Road and the Rironi–Mai Mahiu–Naivasha corridor.

KeNHA attributed the congestion to rising vehicle numbers, especially during the festive season, and urged road users to remain cautious, adhere to lane discipline, and strictly follow traffic regulations to reduce delays.

According to the Authority, traffic volumes have surged significantly along both routes, prompting coordinated efforts with the National Police Service to ensure smooth movement and safety.

Alternative Routes for Motorists

To ease pressure on the affected sections, KeNHA advised motorists to consider several alternative routes, including the Thika–Magumu–Njabini–Olkalou–Dundori–Lanet–Nakuru road.

Other suggested options include the Flyover–Njabini–Olkalou–Dundori–Lanet–Nakuru route, the Naivasha–Njabini–Olkalou–Dundori–Lanet–Nakuru corridor, and the Gilgil–Olkalou–Dundori–Lanet–Nakuru road.

Motorists were also encouraged to use the Ngong–Suswa–Narok–Mau Narok–Nakuru route, the Nakuru–Kampi ya Moto–Eldama Ravine–Makutano road, or the Nakuru–Njoro–Mau Summit route.

KeNHA stated that traffic control efforts are ongoing in partnership with the National Police Service but emphasised that cooperation from motorists remains essential.

“While we continue to manage traffic along these corridors, responsible driving and adherence to traffic rules by all road users are critical to ensuring safe and timely travel,” the Authority said.

Festive Season Gridlock

The advisory comes amid growing frustration among travellers as traffic congestion along the Nairobi–Nakuru highway continues to worsen. 

In recent days, motorists and passengers have experienced long delays, with some spending overnight hours on the road.

Authorities have linked the gridlock to a combination of minor accidents, ongoing road works, poor lane discipline, and increased festive-season travel, which has overwhelmed the single-carriage sections of the highway.
