The government has breathed new life into the Muthaiga-Kiambu-Ndumberi Road project by finally securing a contractor for the multi-billion shilling upgrade.
This project will transform the heavily congested corridor into a modern dual carriageway. Work is set to begin following the signing of an Engineering, Procurement, and Construction (EPC) contract. Under this specific agreement, a single contractor takes full responsibility for the design, material sourcing, construction, and final delivery, which typically streamlines accountability and project speed.
Roads and Transport Cabinet Secretary Davis Chirchir witnessed the signing at Transcom House on Tuesday, marking a major step forward for the long-awaited infrastructure improvement.
KURA confirmed that Stecol Corporation will build the 23.5-kilometer road, with the goal of significantly improving traffic flow along the route.
Stecol Corporation, a prominent Chinese engineering firm established in 1962, operates as a subsidiary of the Power Construction Corporation of China (POWERCHINA). The company focuses on infrastructure, water, power, and urban construction projects across Africa, Asia, and Europe.


In Kenya, Stecol has already completed several high-profile projects, including the Thika Superhighway, Outer Ring Road, and the infrastructure for Tatu City in Ruiru.
The Muthaiga-Kiambu-Ndumberi Road serves as a vital artery connecting Nairobi and Kiambu County. The expansion will cover several key areas, including Muthaiga, Ridgeways, Runda, Kiambu Town, and Ndumberi.
The revamped route will stretch from Pangani and pass through Muthaiga, Ridgeways, Windsor, and Runda before ending in Ndumberi. To streamline traffic, the contractor will build new bridges and overpasses at several key points, including the Muthaiga Golf Club Spur, Coffee Garden, Tala Road, Ridgeways, and the Kirigiti Junction.
