KeNHA has unveiled plans to build a 147km dual carriageway connecting Marua, Nanyuki and Isiolo junction, a major infrastructure project expected to ease travel, improve safety and unlock regional economic growth.
The Kenyan government has rolled out another major road infrastructure project after the Kenya National Highways Authority (KeNHA) confirmed plans to construct a 147-kilometre dual carriageway linking Marua, Nanyuki and the Isiolo junction a move expected to transform transport and trade across the Mt Kenya and northern corridor.
KeNHA chairperson Winfrida Wanjiku said the new highway forms part of an ambitious nationwide programme aimed at modernising Kenya’s road network.
According to her, the government is targeting the dualling of 5,000 kilometres of roads while simultaneously rehabilitating 28,000 kilometres to improve safety, efficiency and driving conditions.
The Marua–Nanyuki–Isiolo corridor is considered a critical economic route connecting agricultural zones, tourism hubs and emerging commercial centres.
Upgrading the road to a dual carriageway is expected to significantly reduce travel time, cut accident risks and support smoother movement of goods and people.
In addition to the new carriageway, Wanjiku confirmed that the 234-kilometre Rumuruti–Nanyuki road will undergo recarpeting to eliminate potholes and enhance road safety.
She noted that these infrastructure upgrades are financed through a KSh5 trillion national infrastructure fund designed to fast-track transformative projects across the country.
The announcement follows President William Ruto’s recent confirmation of a KSh3 billion Meru bypass, aimed at easing congestion and supporting the town’s long-term urban expansion.
Together, the projects reflect a broader government strategy to strengthen connectivity and prepare growing towns for increased economic activity.
However, KeNHA acknowledged that land ownership disputes have slowed some projects in Central Kenya.
The National Land Commission has already compensated affected landowners with KSh3.3 billion, though KSh1.6 billion remains pending due to unresolved claims. Wanjiku assured that these challenges are being addressed to prevent delays.
Local residents and traders along the planned corridor have welcomed the development, saying improved roads will open new business opportunities, attract investment and boost tourism, especially around Nanyuki — a key gateway to Mount Kenya and northern Kenya destinations.
Transport experts say large-scale road upgrades are essential for Kenya’s long-term economic competitiveness, allowing faster logistics, safer travel and better integration between counties.
Once completed, the Marua–Nanyuki–Isiolo dual carriageway is expected to become a vital artery linking central Kenya to the north, reinforcing the country’s push toward a modern, reliable and growth-driven transport system.
