Ngong Road Junction Flyover Hits 89% Completion

Construction works at the Ngong Road-Junction flyover have entered the final stages, with the government reporting an overall progress rate of 89 percent. Recent aerial footage and site updates show that the primary structural elements of the elevated roadway are now largely in place, allowing teams to shift focus toward the finishing phases of the multi-billion shilling infrastructure project.

Engineers on site are currently overseeing the reinforcement of the bridge deck, where steel bars are being laid out in preparation for the final concrete pours. This specific section of the road has long been a bottleneck for motorists traveling between the Nairobi Central Business District, Dagoretti, and Karen. The introduction of the flyover is designed to separate through-traffic from local turning movements at the junction, which previously relied on a heavily congested roundabout.

The project is part of a wider government initiative to modernize the city’s arterial roads, following the successful dualing of other sections of Ngong Road. By elevating the main transit lanes, the Ministry of Transport expects a sharp reduction in travel times for public service vehicles and private motorists alike. On the ground level, the area surrounding the flyover will eventually feature improved slip roads and pedestrian walkways to manage the high volume of foot traffic near the Junction Mall and surrounding commercial hubs.

According to the latest project brief, the remaining 11 percent of the work involves the completion of the surfacing, installation of safety barriers, and the placement of street lighting. Work is also expected to commence on the drainage systems beneath the flyover, which are critical for maintaining road longevity during the rainy seasons. The contractor has maintained a steady presence on site, with multiple shifts of laborers seen working on the rebar grid in recent days.

While the project has faced the typical challenges of urban construction, including the relocation of underground utilities and managing live traffic, the 89 percent mark indicates that the most complex engineering hurdles are now behind the team. Residents and business owners along Ngong Road have been monitoring the progress closely, as the completion of the flyover will signal the end of the temporary diversions and dust that have characterized the area for several months.

The government spokesperson’s office released the updated figures on Tuesday, emphasizing that the project remains a priority for the national infrastructure agenda. Once the concrete on the deck has cured and the asphalt is laid, the final inspections will take place to ensure the structure meets safety standards before it is opened to the public.

Final touches to the underpass sections will follow the opening of the main flyover. These lower-level improvements are intended to facilitate smoother transitions for vehicles exiting toward Naivasha Road or entering the shopping precincts nearby. The completion of this junction is seen as a vital link in the city's transport master plan, connecting the western suburbs more efficiently to the downtown core.
