The government has commenced construction of the Greenpark Terminus Pedestrian Underpass Network as part of ongoing efforts to modernise public infrastructure and reduce congestion in Nairobi’s central business district.

The 500-metre underground walkway is being built at the busy junction of Haile Selassie Avenue and Uhuru Highway. 

According to Interior PS Raymond Omollo, the project aims to enhance commuter safety while improving the flow of both pedestrian and vehicular traffic in one of the city’s most congested intersections.

The facility is planned as a fully integrated 24-hour transit corridor. It will feature lifts, escalators, CCTV surveillance, commercial stalls, public washrooms and water tanks for hygiene and emergency use.

According to the Kenya National Highways Authority (KeNHA), the underpass will be accessible to persons with disabilities and provide retail spaces to support small businesses. 

The design draws inspiration from similar urban transit systems in cities such as Beijing and London.

KeNHA stated that the project is part of a wider initiative to enhance mobility and safety for the thousands of commuters who pass through the Greenpark area daily.

As previously reported by Pulse, the 800-metre steel flyover will allow vehicles to bypass ground-level traffic entirely, cutting travel times for thousands of daily commuters. 

The project also incorporates features to make the space safer and more functional, including dedicated pedestrian walkways, modern drainage systems to reduce flooding during heavy rains, enhanced street lighting, and landscaped surroundings to improve the road’s visual appeal.

Another major undertaking is the viaduct rising along Kenyatta Avenue, whose forest of concrete pillars has sparked public curiosity and online speculation. 

This connection is expected to provide a faster exit route from the CBD, easing pressure on existing junctions and helping to reduce gridlock during peak hours.

Both projects are part of a broader government strategy to modernise Nairobi’s transport network and align it with the needs of a rapidly growing population. 

They complement other initiatives such as the ongoing dualling of key highways, improved non-motorised transport infrastructure, and enhanced traffic management systems.

By creating a safe, accessible, and fully integrated underground corridor, the project will not only protect pedestrians from fast-moving traffic but also help keep vehicles moving more freely at one of the capital’s busiest intersections.
