The Kenya National Highways Authority (KeNHA) has kicked off the hunt for a contractor to drag Kiambu Road; officially the Pangani–Muthaiga–Kiambu–Ndumberi (B32) corridor out of two-lane purgatory.

A fresh procurement notice invites Chinese firms – or joint ventures fronted by them, to pre-qualify by sharp.

Why only Chinese outfits? China Exim Bank is footing the entire bill, and its loan terms insist the main builder hails from home turf.

When completed, the upgrade will convert the current two-lane route into a modern four-lane dual carriageway, complete with two-lane service roads and continuous pedestrian walkways. Commuters can also expect new bridges near Muthaiga Golf Club, Ridgeways, and Runda, plus fresh interchanges at Kamiti and Bypass junctions to keep traffic flowing even during peak hours.

KeNHA notes that the contract uses the FIDIC Silver Book model, meaning the winning consortium will handle design, engineering, and construction under a single turnkey arrangement. Officials have pencilled in for construction and a defects-notification period once the road opens.

Beyond the main trunk, the job covers an extensive web of spur roads and bypasses, including Evergreen-UN Avenue through Runda, Mua Road, and the Githunguri–Sasini–Boma stretch. Six footbridges are also slated for busy pedestrian crossings to curb rising accident rates.
