Motorists using the upcoming Rironi-Mau Summit expressway will pay a toll rate of at least Ksh8 per kilometre, disclosures by the Kenya National Highways Authority (KeNHA) reveal.
This toll is expected to increase by one percent annually to account for inflation and exchange rate fluctuations, according to KeNHA.
The base toll rate was proposed by the consortium of China Road & Bridge Corporation (CRBC) and National Social Security Fund (NSSF) Board of Trustees, who were selected as the Preferred Proponent for the project.
“Based on comparative assessment, the Evaluation Committee concluded that China Road & Bridge Corporation (CRBC) & National Social Security Fund Trustees (NSSF) align with the Contracting Authority’s Output Specifications and PPP Act Cap 430 requirements with a proposed toll rate of Ksh 8 per Km with a 1percent escalation rate per annum,” notice by KeNHA read in part.
According to the disclosure by KeNHA, the expressway will feature eight toll stations and implement an open tolling system, whereby motorists will pay for the distance travelled.
The 175 km road will also feature 15 interchanges, eight footbridges, 25 km of service lanes, eight wildlife crossings, 41 U-turns, 41 underpasses, and 118 bus bays.
The base rate of Ksh8 will apply to passenger cars and small four-wheel vehicles. The highway is expected to be operational from 2028.
The authority settled on the CRBC and NSSF consortium to construct and operate the highway under a 30-year concession.
CRBC also built the Standard Gauge Railway.
Treasury Greenlight
The National Treasury already gave the green light for the construction of the highway following the approval of the project proposal by the National Treasury's Public-Private Partnership (PPP) Committee.
According to KeNHA, works on the Ksh200 billion project are expected to kick off before January 2026 and expected to be completed within two years.
The four-lane highway project is expected to commence at Rironi in Kiambu and traverse through Nyandarua and terminate in Mau Summit, Nakuru County.
