United States-owned infrastructure management firm, Everstrong Capital, has formally submitted a full feasibility study report for the construction of the Nairobi–Mombasa Expressway.
The company announced on Monday evening that it had submitted a 2,300-page feasibility study report detailing several aspects of the highway's construction to the Kenya National Highways Authority (KeNHA).
According to the firm, the comprehensive study outlines the technical, legal, financial, environmental, and social factors to be considered during the project implementation phase.
"In a landmark moment for Kenya and African infrastructure at large, Everstrong Capital has officially submitted the full feasibility study for the 459km Usahihi Nairobi–Mombasa Expressway to the Kenya National Highways Authority (KeNHA)," the company announced.
"The handover represents the most comprehensive and transparent study of its kind in Kenya’s history. This milestone not only affirms the project's full readiness but also marks a critical shift from vision to execution," it added.
During a meeting with KeNHA officials, Everstrong Capital's Senior Advisor, Kyle McCarter, noted that the study fully complied with Kenya’s Public-Private Partnership (PPP) framework.
Addressing the stakeholders, the former US Ambassador to Kenya also revealed that the company was in the process of acquiring Ksh466 billion ($3.6 billion) for the project, adding that the construction was set to begin in early 2026.
He further noted that once completed, the expressway would reduce travel time between Nairobi and Mombasa from 10.5 to 4.5 hours, while unlocking new trade routes, creating thousands of jobs, and enhancing regional connectivity and safety.
"The Usahihi Expressway is not just a road—it’s a model for sustainable, inclusive, and investment-grade infrastructure across Africa," the Senior Advisor reiterated.
Meanwhile, reports suggest that upon its completion, motorists planning to use the highway would be required to pay between Ksh12 and Ksh13 per kilometre to access the road.
The proposed rate contrasts with the charges imposed on motorists using the Nairobi Expressway, which stretches from Westlands in Nairobi to Mlolongo in Machakos and charges Ksh18 per kilometre.
The Nairobi-Mombasa expressway is expected to be one of the longest toll roads in Africa, featuring wildlife corridors, electric vehicle charging and renewable energy infrastructure.
