Kenya is set to break new ground—literally and figuratively—with the upcoming construction of the Usahihi Expressway, a $3.6 billion mega infrastructure project poised to become Africa’s largest toll road.
Scheduled to begin in early 2026, this ambitious 440-kilometer dual carriageway will connect Nairobi to Mombasa, promising to reshape the country’s economic landscape and redefine road travel across East Africa.
A Project of Historic Scale
Dubbed Africa’s largest toll road, the Usahihi Expressway is being developed through a Public-Private Partnership (PPP) spearheaded by Everstrong Capital, a U.S.-based investment firm.
The expressway is designed to be a four-to-six-lane dual carriageway, dramatically improving one of Kenya’s busiest transport corridors.
Currently, it takes between 10 to 12 hours to travel from Nairobi to Mombasa. Once complete, the expressway is expected to reduce that time to just four hours, providing a much-needed boost to logistics, tourism, and commuter convenience.
Financing and Partnerships
The $3.6 billion price tag will be financed through a unique blend of international capital and local investment. Everstrong Capital has secured backing from development finance institutions, global infrastructure investors, and Kenyan pension funds.
The project’s PPP model ensures that it won’t heavily burden taxpayers, with investors set to recoup their capital through toll collections over time.
Kenya National Highways Authority (KeNHA) will provide regulatory oversight and ensure compliance with national infrastructure standards.
Key Features and Innovations
The Usahihi Expressway will feature state-of-the-art infrastructure, including:
-
Smart Tolling Systems for seamless electronic payments
- Advertisement - -
Electric Vehicle (EV) charging stations powered by renewable energy
-
Wildlife overpasses and underpasses to protect Kenya’s rich biodiversity
-
Rest stops and service centers every 50–70 kilometers
-
Emergency response hubs for improved road safety
This focus on sustainability is part of a broader push to incorporate green infrastructure principles into mega projects, aligning with Kenya’s Vision 2030 and international climate goals.
Economic and Social Impact
According to government projections, the expressway is expected to generate tens of thousands of jobs during the construction and operational phases. It will also serve as a catalyst for industrial growth, urban expansion, and regional trade integration across the East African Community (EAC).
“The Usahihi Expressway is not just a road; it’s a symbol of Kenya’s transformation and its commitment to becoming a regional infrastructure hub,” said a spokesperson from Everstrong Capital.
Small businesses along the route are expected to flourish due to improved access, while freight companies anticipate major savings on fuel and turnaround times.
Environmental Considerations
Given the ecological sensitivity of areas along the Nairobi-Mombasa corridor, project developers have pledged to adhere to strict environmental safeguards. Comprehensive environmental and social impact assessments (ESIAs) are underway, with public participation being encouraged.
Renewable energy sources will power ancillary infrastructure, and waste management systems will be integrated into rest stops to minimize pollution.
What’s Next?
Currently, a detailed feasibility study is nearing completion and is expected to be finalized by May 2025. Once approved, the ground-breaking ceremony is slated for Q1 2026. Construction is projected to take 5 to 6 years, with phased rollouts expected as each segment becomes operational.
Conclusion
The Usahihi Expressway represents more than an engineering feat—it is a cornerstone of Kenya’s strategic vision to modernize its infrastructure, facilitate cross-border trade, and spur inclusive economic development.
As ground breaks in 2026, all eyes will be on Kenya as it leads Africa into a new era of smart, sustainable road infrastructure.
