Motorists to Pay KSh 8 Per Kilometre on Key Nairobi–Nakuru Corridor
The Kenya National Highways Authority (KeNHA) has unveiled the proposed tolling structure for the highly anticipated Rironi–Mau Summit Highway, a major infrastructure project aimed at easing congestion along one of Kenya’s busiest transport corridors.
According to project disclosures, passenger vehicles will be charged a base toll fee of KSh 8 per kilometre once the highway becomes operational. The proposed 175-kilometre road stretches from Rironi through Naivasha and Nakuru to Mau Summit, serving as a critical link for trade and travel across the country.
Estimated Toll Charges for Motorists
Based on the proposed rate, motorists traveling the entire Rironi–Mau Summit route will pay approximately KSh 1,400 for a one-way journey. Drivers covering shorter distances will be charged according to the kilometres traveled under an open tolling system.
For example:
- Rironi to Naivasha (approximately 58 km): Around KSh 464 one-way.
- Rironi to Mau Summit (approximately 175 km): Around KSh 1,400 one-way.
Toll Rates Expected to Increase Annually
KeNHA has indicated that the toll charges may be reviewed periodically, with the current proposal providing for a 1% annual adjustment. The review mechanism is intended to account for factors such as inflation, exchange rate fluctuations, and operational costs.
Highway Upgrade Aims to Reduce Traffic and Travel Time
The Rironi–Mau Summit project is expected to transform travel between Nairobi and Western Kenya by expanding the existing road network into a modern dual carriageway. Plans include additional lanes in high-traffic sections, improved interchanges, service roads, and enhanced safety infrastructure.
Government officials argue that despite the toll charges, motorists will benefit from shorter travel times, lower vehicle operating costs, and improved road safety once the project is completed.
Alternative Routes to Remain Available
To address concerns about mandatory toll payments, KeNHA has stated that alternative routes will be identified and made available for motorists who choose not to use the tolled highway. The authority says this approach will ensure road users have the freedom to select routes that best suit their needs and budgets.
Strategic Importance of the Project
The Rironi–Mau Summit corridor forms part of Kenya’s Northern Corridor transport network, which facilitates the movement of goods from the Port of Mombasa to Western Kenya and neighboring countries including Uganda, Rwanda, South Sudan, and the Democratic Republic of Congo. The expansion project is expected to boost regional trade, improve logistics efficiency, and enhance economic growth.
Conclusion
The proposed tolling system marks a significant shift in the financing and maintenance of Kenya’s road infrastructure. While the KSh 8 per kilometre charge has generated public debate, the government maintains that the upgraded highway will deliver substantial benefits through improved mobility, reduced congestion, and enhanced safety. As the project progresses, motorists will be closely watching how the tolling framework is implemented and whether the promised benefits outweigh the additional travel costs.
