The Kenya Urban Roads Authority posted fresh details this week on the Ngong Road–Naivasha Road Flyover. The authority highlighted the main features of the project that continues to advance at the busy junction.
Construction has reached a stage where the elevated structure is clearly taking shape. At its core is an 800-metre dual carriageway raised above ground level. This design lifts main traffic flows over the intersection where Ngong Road meets Naivasha Road.

Pedestrian walkways line both sides of the elevated section. Dedicated cycling lanes run parallel. Modern drainage systems complete the listed components to manage water flow.
Once finished the flyover should cut travel time for vehicles heading between Ngong Town and Nairobi’s central business district. Ngong Road serves as one of the primary southwest routes out of the city. It handles heavy commuter traffic from residential suburbs and towns in Kajiado County.
The junction near Junction Mall has long been a point of congestion. Elevating part of the road separates through traffic from turning movements at ground level.
KURA is responsible for developing and maintaining national urban trunk roads. The authority often shares progress updates on its platforms. This post included four images credited to PS Raymond Omollo showing concrete supports, asphalt surfacing and safety barriers already in place.

Such visuals allow the public to see the scale of the work. The flyover spans the junction plus approach areas without requiring a full rebuild of the surrounding road network.
Commuters on this corridor face daily delays during rush hours. Many travel from Ngong and nearby areas for work in the CBD. Improvements at key junctions like this one aim to ease pressure at specific bottlenecks.
The addition of pedestrian walkways and cycling lanes goes beyond basic vehicle capacity. It provides safer options for people on foot and on bicycles. Drainage elements address a common issue in Nairobi where heavy rains can disrupt low-lying sections.
Public responses to the update have been mixed. Some welcomed the visible progress while others criticised the time taken for a section under one kilometre. A few raised questions about maintenance on other completed roads and priorities at different junctions across the city.

KURA did not include a revised completion timeline in this post. The focus remained on describing the finished features and their expected benefits. Similar projects in Nairobi have shown that final surfacing, road markings and connections can take additional time.
The structure relies on standard reinforced concrete and steel elements. When open it will carry two-way traffic above existing ground movements. Pedestrians and cyclists will use separate paths away from vehicles.
This intervention fits a pattern of targeted upgrades at busy intersections. Vehicle numbers in the capital have grown steadily. Addressing junctions offers quicker relief in built-up areas where full corridor expansions face space constraints.
For regular users of Ngong Road the update gives a clearer picture of what to expect. The elevated section is advanced though finishing works continue.
