The Kenya National Highways Authority (KeNHA) has announced that motorists will be required to pay Sh8 per kilometre to use the Rironi–Mau Summit Expressway once the expansion into a dual carriageway is completed.
According to the Kenya National Highways Authority (KeNHA), the project will be jointly developed and overseen by the China Road and Bridge Corporation (CRBC) and the National Social Security Fund (NSSF).
“Financial evaluation indicates that the CRBC and NSSF feasibility proposal is the preferred option due to its ability to handle the high costs and provide a lower toll of Sh8 compared to the Sh10 proposed by Hi-Speed Road & Bridge International Engineering Co. Ltd,” KeNHA said in documents seen by our sources.
The 175-kilometre Nairobi–Nakuru–Mau Summit highway is expected to cost approximately Sh90 billion and is scheduled for completion by June 2027. This figure is less than half of the earlier estimated Sh190 billion proposed by a French consortium, whose plan was cancelled by President William Ruto over cost concerns.
Earlier this year, National Treasury Cabinet Secretary John Mbadi said the expansion of the highway would ease congestion and improve transport links in western Kenya.
“We borrowed money to build roads in rural areas, but key corridors like the Nairobi–Nakuru highway remained single carriageways. Making it a dual carriageway will help travellers reach their destinations faster,” Mbadi said.
