Government Signs Ksh38.7 Billion Deal to Dual Kiambu Road

The Ministry of Roads and Transport has formalized a multi-billion shilling agreement to expand one of the most congested arterial routes in the Nairobi Metropolitan Area. On Tuesday, March 17, 2026, Cabinet Secretary Davis Chirchir witnessed the signing of the Engineering, Procurement, and Construction (EPC) contract for the dualling of the Muthaiga–Kiambu–Ndumberi Road.

The 23.5-kilometre project, awarded to Chinese firm Stecol Corporation, is valued at Ksh38.7 billion. The agreement, signed at Transcom House in Nairobi, marks the transition of the project from the planning and procurement phases to active implementation. The Kenya Urban Roads Authority (KURA) will oversee the delivery of the infrastructure, which is expected to take 36 months to complete.

The scope of work involves converting the existing two-lane B32 road into a modern four-lane dual carriageway. To manage the high volume of traffic flowing between Nairobi and Kiambu County, the design includes the construction of service lanes, pedestrian walkways, and six footbridges. These safety features are slated for high-traffic zones, including Ridgeways, Thindigua, and Kiambu Town.

The project is financed through a loan from China’s EXIM Bank. According to official project briefs, the total cost includes approximately Ksh7.2 billion dedicated to land acquisition and the relocation of essential services such as water and power lines. This budgetary provision addresses the complexities of working within a densely populated commercial and residential corridor.

Geographically, the upgraded route begins at Pangani and traverses through Muthaiga, Ridgeways, Windsor, and Runda before terminating at Ndumberi. Engineering plans detail the inclusion of several new bridges and overpasses at critical junctions. Key structural additions are planned for the Muthaiga Golf Club Spur, Coffee Garden, Tala Road, and the Kirigiti Junction to eliminate current bottlenecks.

Director General of KURA, Eng. Silas Kinoti noted during the ceremony that the expansion is intended to support economic growth by reducing travel times and vehicle operating costs. The project follows a standard EPC model under the FIDIC Silver Book framework, which places the responsibility for design and construction certainties on the contractor.

Upon the conclusion of the three-year construction period, the contract includes a two-year defects liability period. This ensures the contractor remains responsible for any structural or maintenance issues that arise shortly after the road is opened to the public.
