Nairobi’s Ksh.2B Greenpark Pedestrian Underpass Nears Completion

The much-anticipated Nairobi Greenpark Pedestrian Underpass is now 97% complete and set to officially open soon, marking a major milestone in the city’s transport infrastructure.

A Game-Changer for Nairobi’s Pedestrians

Located at the busy Haile Selassie–Uhuru Highway junction, the Ksh.2 billion project is designed to ease congestion and improve pedestrian safety in one of Nairobi’s busiest areas.

The National Assembly’s Transport and Infrastructure Committee recently inspected the site, praising it as a transformative project that will serve more than 21,000 pedestrians daily. During peak hours, the facility is expected to handle up to 8,500 users.

Key Features of the Greenpark Underpass

The Greenpark Underpass will consist of four tunnels—two beneath Haile Selassie Avenue and two under Uhuru Highway—measuring between 29 and 106 metres in length. These tunnels will connect major routes such as Mombasa Road, Upper Hill, Westlands, and the Railway terminus, creating seamless movement across the city.

Final Touches Before Opening

According to the Kenya National Highways Authority (KeNHA), the remaining work includes interior finishes, electrical and mechanical installations, landscaping, and setting up CCTV systems. The project is expected to be fully operational by December.

Transforming Nairobi’s Urban Mobility

Once opened, the underpass will significantly reduce conflicts between vehicles and pedestrians, cut travel times, and improve safety. It is also expected to enhance economic activity within the CBD by providing both convenience and business opportunities.

Urban planners believe this project is a model for future pedestrian infrastructure, with calls to replicate similar underpasses in other high-risk areas of Nairobi to reduce accidents and improve walkability.
