KeNHA Reveals Toll Charges for Rironi–Naivasha–Gilgil and Rironi–Maai Mahiu Highway

The Kenya National Highways Authority (KeNHA) has disclosed that motorists using the Rironi–Naivasha–Gilgil (A8) and Rironi–Maai Mahiu–Naivasha (A8 South) roads will pay a toll fee of Sh8 per kilometer once the Public-Private Partnership (PPP) project becomes operational.

In a notice issued on Tuesday, June 23, 2026, KeNHA confirmed that the 139-kilometre highway project will operate as a toll road under a 30-year concession agreement signed between the authority and a consortium comprising China Road and Bridge Corporation (CRBC) and the National Social Security Fund (NSSF) Board of Trustees.

The project covers approximately 81 kilometres of the A8 road and 58 kilometres of the A8 South road, stretching from Rironi Interchange through Maai Mahiu to Naivasha, and passing through Kiambu, Nyandarua and Nakuru counties.

KeNHA said the toll tariff has been set at KSh 8.00, with future adjustments to be made in accordance with the project agreement and subject to regulatory approvals.

The authority noted that the road will be developed under a Design, Build, Finance, Operate, Maintain and Transfer (DBFOMT) model, with the private consortium bearing the primary financing responsibility.

The Government’s financial exposure will be limited to obligations expressly outlined in the agreement, while the private partner will handle construction, operation and maintenance of the highway.

The project will include the design, construction, and maintenance of interchanges, bridges, drainage structures, tolling systems, road safety features and other supporting infrastructure.

KeNHA said the initiative is expected to ease traffic congestion, reduce travel time and vehicle operating costs, improve road safety, and enhance connectivity between Nairobi and the Rift Valley region.

Motorists will benefit from improved road standards, while the project is also expected to stimulate trade, tourism, and economic activity along the corridor.

The toll road will be operated for a period of 30 years, after which it will be transferred back to KeNHA in line with the concession agreement.

During the concession period, the private consortium will be responsible for maintenance and service delivery, subject to performance monitoring by KeNHA.

The authority will oversee compliance with safety standards, construction milestones, environmental requirements, and operational performance indicators.

KeNHA added that the disclosure is part of its commitment to transparency in public-private partnerships and is in line with National Treasury requirements on PPP project disclosures.

“This disclosure is made pursuant to Section 59 and 69(1) of the Public Private Partnerships Act (Cap 430) to notify members of the public of the PPP Committee’s decision approving the Project and Financial Risk Report, and the subsequent execution of the Project Agreement between KeNHA and the CRBC–NSSF consortium,” the authority said.
