KeNHA Increases Toll Fees On Strategic Nairobi-Nakuru Highway Section

The Kenya National Highways Authority (KeNHA) has adjusted the toll charges for motorists using the newly revamped Gilgil-Mau Summit section of the Nairobi-Nakuru highway.

Drivers on the ninety-four-kilometre road stretch will pay eight shillings and fifty cents per kilometre, which is fifty cents higher than the rate applied to the neighboring Rironi-Gilgil portion.

This fee adjustment represents a direct shift in the cost projections for the regional transport link, which connects Nairobi and Nakuru counties.

According to official documentation from the state agency, the entire two-hundred-and-thirty-three-kilometre highway will demand a total toll payment of one thousand nine hundred and eleven shillings, if the entire corridor becomes fully tolled.

The continuous development of the highway relies on the Public-Private Partnership (PPP) model, where private consortia handle the heavy construction, operations, and long-term maintenance of the strategic artery.

Under these long-term agreements, the private operators manage the infrastructure for three decades, and they collect user charges to recover their massive initial capital investments.

The newly announced toll pricing structure serves as a critical mechanism for the state to manage traffic flows, while funding the expansive infrastructure obligations without increasing the direct public debt burden.

KeNHA intends to implement these multi-tier pricing structures across different vehicle classifications, ensuring that commercial trucks, public service vehicles, and private saloon cars pay proportionate rates for using the modern asset.

The upgrades on the highway include the widening of the existing lanes into a dual-carriageway system, which eliminates persistent traffic bottlenecks, and minimizes the vehicle operating expenses for regional logistics firms.

With the inclusion of modern automated weighbridge systems, including High Speed Weigh in Motion (HSWIM) technology, the authority aims to curb axle-load non-compliance, which heavily contributes to rapid pavement deterioration.

This administrative decision emerges at a time when the state is actively pursuing alternative funding mechanisms, including the newly introduced National Infrastructure Fund (NIF), to fast-track priority road networks.

Engineering reviews indicate that the previous infrastructure on the Northern Corridor faced severe structural constraints, which delayed travel times between the capital city, and the western parts of Kenya.

By dualing the Rironi-Mau Summit axis, the government intends to streamline the movement of transit goods heading towards neighboring landlocked countries, although local commuter logistics will bear the immediate toll adjustments.

Motorists have raised questions regarding the cumulative financial impact of these toll roads, but the state maintains that the savings accrued from reduced fuel consumption, and lower maintenance costs justify the fees.

The state road agency confirmed that future tariff adjustments will strictly follow the statutory provisions outlined in the project agreement, subject to regular economic reviews, and necessary regulatory approvals.

The construction works on the separate tranches are being executed by specialized international firms, who are tasked with delivering international engineering standards across the rugged Rift Valley terrain.

Local leadership in Nakuru County has expressed support for the safety benefits of the dual-carriageway design, given the history of fatal multi-vehicle accidents along the old single-lane highway corridors.

The rollout of the new highway tolls underscores Kenya's evolving infrastructure strategy, which prioritizes user-funded capital models to maintain critical transport pathways across the country, while protecting public coffers.
