What if you could slash your commute through one of Africa’s most congested cities from two hours to just 20 minutes? That’s the bold promise of the Nairobi Expressway—a gleaming new highway in the sky that’s dividing opinions on the ground. Is it a long-overdue solution, or just a glossy bypass to deeper transport problems?
The Urban Transport Crisis in Nairobi
Nairobi, home to more than 4.4 million people, is infamous for its traffic congestion. During peak hours, commuting within the city can take up to three hours for a round trip, especially on arteries like Mombasa Road, Uhuru Highway, and Waiyaki Way. Private vehicles, Matatus (privately owned minibuses), boda bodas (motorbike taxis), and buses all battle for limited space.
The city’s public transport system is fragmented and largely informal. Matatus, though flexible and affordable, operate in a chaotic manner, lacking consistent schedules or centralized management. There’s no metro, no light rail, and bus rapid transit (BRT) projects are still in early stages.
Enter the Nairobi Expressway
Launched in May 2022, the Nairobi Expressway is a 27.1-kilometer elevated highway running from Mlolongo, past Jomo Kenyatta International Airport (JKIA), through the CBD, to Westlands. Built under a public-private partnership model by China Road and Bridge Corporation (CRBC), the project cost approximately $650 million and was completed in just under three years.
The Expressway was touted as a revolutionary solution to Nairobi’s gridlock. With 11 interchanges, 9 toll stations, and a design capacity of up to 120,000 vehicles per day, it was expected to dramatically reduce travel time across the city.
How the Toll System Works
Using the Nairobi Expressway isn’t free. It operates on a user-pay model, where drivers are charged based on distance traveled and vehicle type. Fees range from KES 120 to KES 360 (roughly $0.90 to $2.70) for most private cars. Larger trucks and commercial vehicles pay significantly more—up to KES 1,800 for the full length.
Drivers can choose between manual tolling, using cash or mobile money, and electronic toll collection (ETC), which involves installing a digital tag on the vehicle’s windshield. ETC users enjoy faster lane access and discounts for frequent travel.
The road is well-maintained, patrolled, and lit at night. Cameras and smart surveillance systems enhance safety and monitoring—a sharp contrast to Nairobi’s notoriously chaotic streets.
Impact on Traffic and Commutes
So, has the expressway solved Nairobi’s traffic woes?
Travel times along the expressway have plummeted. What used to take two hours on Mombasa Road during rush hour can now be covered in 15 to 20 minutes. The expressway has also relieved pressure on parts of the old road network, especially around JKIA and the CBD.
However, this relief is not evenly distributed. Only about 30,000–40,000 vehicles use the expressway daily, far fewer than the predicted 120,000. The high toll costs mean most Matatus, buses, and low-income commuters can’t afford it. For them, the old roads remain jammed and underfunded.
Additionally, feeder roads leading to and from the Expressway often remain congested. Experts call this the "last-mile problem"—the expressway works well only if your origin and destination are directly along its route.
What People Are Saying
The public is divided. Many private car users praise the Expressway for its convenience and speed. Business travelers and airport commuters say it has reduced stress and improved punctuality. For the city’s elite, it’s a game-changer.
But for the majority of Nairobi’s residents, it’s an expensive luxury. Urban planners have voiced concern that the project benefits the few while neglecting the many. In a city where 60% of people rely on informal public transport, an elevated toll road may not be the most equitable solution.
A Stepping Stone or a Detour?
The Nairobi Expressway is undeniably a feat of engineering and a symbol of ambition. It shows what’s possible when large-scale infrastructure is delivered efficiently. But it’s also a reminder that speed and access aren’t the same for everyone.
As Nairobi plans future mobility projects—like BRT lines, railway upgrades, and walkable neighborhoods—the lessons from the Expressway are clear: infrastructure must serve the city, not just the motorist.
