The Cabinet has approved the dualling of the 23.5-kilometre Muthaiga–Kiambu–Ndumberi road in a move to ease congestion and improve mobility between Nairobi and Kiambu counties. 

According to a dispatch from State House on Tuesday, November 11, the project will expand the existing two-lanes into a dual carriageway, complete with bypasses, loops, and access roads to increase capacity and reduce travel times.

The Cabinet also said the project will incorporate non-motorised transport lanes and commuter facilities to enhance road safety and accessibility. 

“Cabinet gave the green light to the dualling of the 23.5km Muthaiga-Kiambu-Ndumberi road to ease congestion and improve mobility between Nairobi and Kiambu counties.

“The project will expand the existing two-lane highway into a dual carriageway, complete with bypasses, loops, and access roads to increase capacity and reduce travel times,” read the dispatch in part.

The corridor serving Muthaiga, Runda, Ridgeways, and Kiambu Town, currently experiences chronic traffic congestion, especially during peak hours.

“The dualling is part of the government’s broader effort to modernize Nairobi’s metropolitan transport network in line with Kenya Vision 2030 and the UN Sustainable Development Goals on infrastructure and mobility,” the Cabinet added.

This comes months after the Kenya National Highways Authority (KeNHA) abruptly canceled the tender for upgrading the Muthaiga-Kiambu-Ndumberi road.

The authority had, on July 15, 2025, advertised the tender for the road, which was only open to Chinese firms or Chinese-led joint ventures.

“The Government of the Republic of Kenya has received commitment from the People’s Republic of China through the China Export Import (EXIM) Bank to finance the cost of the Capacity Enhancement of Pangani – Muthaiga – Kiambu – Ndumberi (B32) Road. The financing agreements shall be signed upon finalization of the commercial contract,” read the advert in part.

However, the road agency revoked the tender just a week later without providing an explanation.

The initial advertisement had drawn criticism from the stakeholders who complained about limiting the tender to Chinese companies.
