The Nairobi Expressway is one of Kenya’s most ambitious infrastructure projects, designed to ease traffic congestion and improve mobility within the capital. Stretching 27 kilometers from Mlolongo to Westlands, the expressway has transformed the way people move across Nairobi, reducing travel time significantly and enhancing convenience for motorists. The project, which was undertaken as a public-private partnership (PPP), is operated by the China Road and Bridge Corporation (CRBC) under a concession agreement that allows the company to manage and maintain the road before eventually handing it over to the government.
Construction and Development
The construction of the Nairobi Expressway began in 2020 as part of Kenya’s broader plan to modernize its road infrastructure. The expressway was built as an elevated highway along the existing Mombasa Road, Uhuru Highway, and Waiyaki Way corridor, which had long been notorious for traffic congestion. The project was completed within a record time of two years, with the road officially opening for public use in 2022.
The expressway features multiple entry and exit points, allowing seamless access to key locations such as Jomo Kenyatta International Airport (JKIA), the central business district (CBD), and commercial hubs in Westlands. The use of modern construction technology, including precast concrete and elevated viaducts, has helped maximize space while minimizing disruptions to the existing road network.
Tolling System and Payment Options
Unlike other roads in Nairobi, the Nairobi Expressway operates on a toll system where motorists pay a fee to use the road. The toll charges vary depending on the distance traveled and the type of vehicle, with higher rates for larger commercial vehicles and lower rates for smaller cars.
To enhance efficiency, the expressway uses an electronic toll collection (ETC) system that allows registered users to pass through toll gates seamlessly using a pre-installed card. There is also a manual toll collection (MTC) system where motorists can pay cash or use mobile money services. The adoption of cashless payments has helped reduce delays and improve traffic flow along the expressway.
Impact on Traffic and Economy
The Nairobi Expressway has significantly reduced travel time for motorists who previously spent hours stuck in traffic along Mombasa Road and Uhuru Highway. What used to be a two-hour journey from Jomo Kenyatta International Airport to Westlands can now be completed in under 20 minutes, making the expressway a game-changer for commuters and businesses.
The improved mobility has had a positive impact on the economy, as businesses can operate more efficiently without the delays caused by traffic congestion. The expressway has also enhanced accessibility to major economic zones, including the industrial area, commercial districts, and residential neighborhoods. Property values along the expressway corridor have increased, as improved infrastructure has made these areas more attractive for investment.
Safety and Security Features
The Nairobi Expressway has been designed with safety in mind, incorporating features such as CCTV surveillance, emergency response teams, and clearly marked lanes. The road is monitored 24/7 to ensure swift intervention in case of accidents or emergencies. Additionally, speed limits have been set to prevent reckless driving and enhance road safety.

To minimize pedestrian-related accidents, the expressway is elevated in most sections, separating it from normal traffic and pedestrian crossings. Security measures, including regular patrols and toll gate monitoring, have also been implemented to ensure the safety of road users.
Challenges and Public Concerns
Despite its many benefits, the Nairobi Expressway has faced some challenges. One major concern is the toll charges, which some motorists consider high, making the road less accessible to low-income users. There have also been incidents of accidents and reckless driving, leading to calls for stricter enforcement of traffic regulations on the expressway.
Another challenge is the integration of the expressway with existing roads. While the expressway has improved traffic flow for those who use it, congestion remains an issue on adjacent roads, particularly for motorists who cannot afford the toll fees. The government has been exploring ways to address this, including upgrading alternative routes to ensure a balanced transport network.
Future Prospects and Expansion Plans
The success of the Nairobi Expressway has sparked discussions about expanding similar infrastructure projects to other parts of the country. There are ongoing proposals to extend the expressway beyond Westlands to Rironi, as well as build additional expressways in other urban centers such as Mombasa and Kisumu.
The government is also looking into integrating public transport options with the expressway, potentially including dedicated lanes for buses to enhance mass transit efficiency. Future plans could also involve expanding the electronic toll collection system to make it more seamless for users.
