Plans for the Sh455 billion Mombasa-Nairobi Expressway are gaining momentum, with construction expected to begin in early 2026.
The project is being spearheaded by Usahihi Expressway Limited, with Everstrong Capital, a U.S.-based investor, leading the fundraising effort set to conclude by December.
The 444-kilometre, four-lane dual carriageway aims to cut travel time between Mombasa and Nairobi from 10 to just four hours, while reducing fuel costs by up to 30%.
According to Usahihi chairman and former U.S. Ambassador to Kenya, Kyle McCarter, five contractors will work simultaneously to complete the project within four years.
“We will have five contractors that will be doing the construction of the road all at once so that we can get this done as soon as possible for people to enjoy the road,” McCarter said during a recent meeting with Makueni County officials, according to Business Daily.
Unlike many mega-infrastructure projects, this expressway will not rely on taxpayer funding.
Instead, private developers will finance the road and recoup their investment over 30 years through toll fees, after which it will be handed over to the government.
“The Mombasa-Nairobi Expressway project will not cost Kenyan taxpayers a cent because it is sponsored by private developers who will operate the road for 30 years to recoup their investment by charging toll fees before handing it over to the Kenyan Government,” he said.
Key features include 12 highway exits, eight rest areas, and three wildlife crossings. Land acquisition, budgeted at Sh129 billion, is currently underway, and a feasibility report has been submitted to the National Environmental Management Authority.
While the project promises major economic and transport benefits, local leaders and environmental advocates have raised concerns.
Makueni Deputy Governor Lucy Mulili and MP Mwengi Mutuse stressed the need for local job creation and protection of existing trade corridors.
Environmentalist Halinishi Yusuf warned about the ecological impact of sand extraction, referencing past damage during SGR construction.
Stakeholder consultations have begun, with Makueni County the first stop in a broader engagement campaign.
