The Kenya National Highways Authority (KeNHA) has proposed a toll rate of Ksh 8 per kilometre for motorists using the soon-to-be-dual Nairobi–Mau Summit Highway, one of Kenya’s busiest transport corridors.
According to KeNHA, the 175-kilometre road will be expanded into a dual four-lane carriageway under a Public-Private Partnership (PPP) involving the China Road & Bridge Corporation (CRBC) and the National Social Security Fund (NSSF) Board of Trustees.
The Ksh 171.4 billion project, which is expected to take two years to complete, aims to ease the heavy congestion that has long plagued the Nairobi–Nakuru–Mau Summit stretch, a key route for trade between Nairobi and the Rift Valley.
KeNHA’s proposal sets the base toll rate for passenger cars at Ksh 8 per kilometre from the first operational year, 2028, with an annual increase of 1% to adjust for inflation and economic changes.
To ensure affordability, the government has indicated that the final rate will be subject to negotiation following stakeholder consultations.
“The government of Kenya should negotiate a competitive toll tariff as per the contracting authority’s stakeholder engagement findings,” KeNHA’s report reads in part.
The project will be financed through a mix of 75% debt and 25% equity, with the NSSF’s involvement marking a significant local investment in national infrastructure. Under the PPP framework, the consortium will also assume traffic and revenue risks, shielding taxpayers from possible deficits.
The dual carriageway is expected to significantly reduce travel time and improve road safety for thousands of motorists and long-distance truck drivers using the busy corridor daily.
KeNHA has also identified other major highways likely to attract tolls in future, including the Thika Superhighway, Kenol–Sagana–Marua Road, Mombasa Southern Bypass, and Dongo Kundu Bypass, in line with the government’s new Road Tolling Policy.
This proposal comes shortly after the Ministry of Transport approved a 50% increase in toll charges on the Nairobi Expressway, sparking fresh debate over the cost of road use in Kenya
