NAIROBI, Kenya, Oct 24 – Motorists will pay Sh8 per kilometer to use the Rironi–Mau Summit Expressway once its expansion to a dual carriageway is complete, the Kenya National Highways Authority (KeNHA) has disclosed.
According to KeNHA, the project will be undertaken and managed jointly by the China Road and Bridge Corporation (CRBC) and the National Social Security Fund (NSSF).
“The financial evaluation reveals that CRBC and NSSF’s feasibility study is the preferred option due to its greater toll affordability, offering a lower tariff of Sh8 compared to Sh10 proposed by Hi-Speed Road & Bridge International Engineering Co. Ltd,” KeNHA said in documents seen by Capital Business.
The 175-kilometre Nairobi–Nakuru–Mau Summit dual carriageway will cost about Sh90 billion and is slated for completion by June 2027. The cost is less than half of the Sh190 billion initially quoted by a French consortium whose deal was terminated by President William Ruto over cost concerns.
Earlier this year, National Treasury Cabinet Secretary John Mbadi said the road’s expansion would ease congestion and improve connectivity to western Kenya.
“We borrowed money to build roads in rural areas, yet an important route like the Nairobi–Nakuru highway remained single-lane. Making it dual will help travelers reach their homes faster,” Mbadi noted.
