The long-awaited upgrade of the Nairobi–Nakuru–Mau Summit and Rironi–Maai Mahiu–Naivasha highways is progressing steadily, with two Chinese firms submitting formal proposals to spearhead the transformation of these critical road corridors. The move marks a significant step in Kenya’s ongoing efforts to modernize its transport infrastructure and reduce traffic congestion along some of the country’s busiest routes.
The Kenya National Highways Authority (KeNHA) recently disclosed that it had received Project Information Proposals (PIPs) from the two Chinese firms, signaling the beginning of an intensive review process. Both companies are expected to meet stringent technical and financial benchmarks before being considered for the final selection.
The Nairobi–Nakuru–Mau Summit highway is one of Kenya’s most vital transportation arteries, connecting the capital to major towns in the Rift Valley and serving as a key link in the Northern Corridor that facilitates regional trade between Kenya, Uganda, Rwanda, and beyond. The planned upgrade, which includes both the Nairobi–Nakuru–Mau Summit section and the Rironi–Maai Mahiu–Naivasha spur, aims to ease chronic traffic bottlenecks, enhance safety, and promote smoother logistics for both passenger and freight transport.
The upgrade will likely involve converting the current road into a modern dual carriageway, complete with interchanges, service lanes, and improved drainage systems. These enhancements are expected to significantly reduce travel time, improve road safety, and lower vehicle operating costs for motorists and freight operators alike.
While the names of the bidding companies have not been publicly disclosed, industry observers note that Chinese firms have historically played a major role in Kenya’s infrastructure development. Over the years, several Chinese state-backed and private construction companies have executed large-scale road, rail, and energy projects across the country. Their experience in delivering such complex undertakings positions them as strong contenders for this latest venture.
As part of the evaluation process, the two firms will be assessed based on their financial capacity to fund and complete the project, as well as their technical know-how and track record in similar infrastructure projects. The winning bidder is expected to carry out the project under a Public-Private Partnership (PPP) model, where the firm would design, finance, build, operate, and maintain the highway over an agreed concession period. This model allows the government to leverage private investment while ensuring long-term service quality and maintenance.
The road upgrade is not only a transport priority but also a key enabler of economic growth. The route supports a large volume of agricultural trade from the Rift Valley and Central Kenya, as well as tourism and industrial activities. Enhancing its capacity and efficiency will have a ripple effect on regional development and trade facilitation.
The submission of proposals sets the stage for further consultations, environmental and social impact assessments, and public engagement as the project moves into advanced stages of planning. Once a contractor is selected and financial agreements are finalized, construction is expected to commence promptly, bringing the long-anticipated project to life.
This development reflects a broader national vision to modernize Kenya’s infrastructure backbone, positioning the country as a competitive gateway to East and Central Africa. With the upgrade of this highway corridor, Kenya hopes to achieve more efficient mobility, increased investment opportunities, and improved standards of living for communities along the route.
