Nairobi is edging closer to easing one of its most frustrating traffic bottlenecks, with the Ngong Road–Naivasha Road flyover at Junction Mall now entering its final stretch.
The project, being implemented by the Kenya Urban Roads Authority (KURA), is shaping up as a key piece in the city’s broader push to modernise its road network and prepare for rising urban demand.
Once complete, the flyover is expected to significantly cut congestion along the busy Ngong Road corridor, a route that serves thousands of commuters daily linking satellite towns like Ngong and Karen to Nairobi’s central business district.
At the heart of the project is an 800-metre elevated dual carriageway, including a 254-metre steel bridge, designed to separate through-traffic from vehicles accessing the busy Junction Mall intersection.
The structure itself is largely done, with contractors now focusing on the final works such as deck installation, tarmacking, road markings and installation of high-mast LED lighting.
Beyond easing traffic, the design also factors in non-motorised transport. Pedestrian walkways, cycling lanes and improved drainage systems have been included to enhance safety and address frequent flooding that has long plagued the area.
The timing of the project is also strategic. Nairobi is among host cities preparing for the 2027 Africa Cup of Nations (AFCON), which Kenya will co-host alongside Uganda and Tanzania.
The flyover is expected to improve access to key venues, including the upcoming Talanta Sports City complex, positioning the capital to handle increased traffic during the continental tournament.
Transport planners say the impact could be immediate once opened. Travel time from Ngong to the CBD, which can stretch to nearly two hours during peak traffic, is projected to drop to under 30 minutes.
The government, through the State Department for Internal Security, has also been working alongside road agencies to manage traffic flow during construction and enforce safety measures, especially for pedestrians and cyclists who continue to use the corridor daily.
The project adds to a growing list of road upgrades in Nairobi aimed at decongesting major arteries, including recent improvements along Waiyaki Way, Mombasa Road and the ongoing Nairobi Expressway expansion efforts.
If delivered on schedule, the Junction flyover could quickly become one of the most visible signs of Nairobi’s attempt to fix its traffic problem—and keep pace with its fast-growing population.
