Kiambu Road To Be Expanded To A Four-Lane Dual Highway, Govt Announces

The Government of Kenya has announced plans to expand Kiambu Road from a two-lane single carriageway to a four-lane dual highway with two service lanes on both sides.

In a notice seen by the Star, the state, through the Kenya National Highways Authority (KeNHA), has invited eligible Chinese contractors to submit prequalification applications for the road infrastructure project.

The project will cover Pangani – Muthaiga – Kiambu – Ndumberi (B32) Road and the Adjacent Road Network.

It will be financed through a loan from the China Export-Import (EXIM) Bank.

KeNHA has invited applications for prequalification from eligible Chinese firms under Tender No. KeNHA/2889/2025. The deadline for submission is Friday, August 22, 2025, at 11 am.

According to KeNHA, the project will significantly improve traffic flow along the eastern part of the Nairobi Metropolitan area.

It targets key corridors including parts of Kiambu Road and the Thika Superhighway.

“The project will also improve the level of service and safety for road users and enhance accessibility through service roads and non-motorised transport facilities,” KeNHA stated.

The works will be implemented in accordance with the FIDIC Silver Book standards. They include widening the existing road from a two-lane to a four-lane dual carriageway, as well as the construction of new bridges, pedestrian walkways, and interchanges.

A total of six pedestrian footbridges will also be installed along the route.

Some of the main components of the project include the Muthaiga – Kiambu Road – Ndumberi stretch and key spurs such as Ridgeways Road, Kiambu Road to Thika Road, and UN Avenue through Runda.

Several road junctions will also be upgraded.

The construction period is set at 36 months, with a 24-month defects notification period.

The scope of work includes road furniture, signage, traffic management, and provision of bus bays.

KeNHA emphasised that the project aims to ease congestion and improve mobility along the corridor.

“Upgrading of the entire project road to a four-lane dual carriageway, including pedestrian walkways, will ensure better service delivery,” said the statement.

The authority insisted that applicants must be Chinese contractors or consortia led by Chinese enterprises.

The tender document outlines requirements such as financial capability, technical experience, and adherence to Chinese government-supported financing protocols.

Interested firms can access the full prequalification documents from KeNHA’s website (www.kenha.co.ke) or the Public Procurement portal (tenders.go.ke). The authority also provided a contact email for inquiries: [email protected].

The completed applications should be addressed to the Director of Development at KeNHA’s headquarters, located at Barbara Plaza, Airport South Road, Nairobi.

Submissions must be made in person and clearly labelled with the tender title and number.

“All interested bidders are required to continuously check KeNHA and PPIP websites for updates and clarifications,” the notice added.

The project is part of a broader initiative by the Kenyan government to modernize urban infrastructure and boost economic growth through improved road connectivity.
