The long-awaited Ngong Road-Naivasha Road Flyover at Junction Mall in Nairobi has officially opened, nearly a year ahead of schedule, easing one of the city’s worst traffic jams.

The 820-metre structure, comprising roughly 400 metres of elevated flyover and 400 metres of upgraded approach roads, is a four-lane design incorporating dedicated pedestrian walkways and cycling lanes.

It allows through-traffic on Ngong Road to bypass vehicles turning onto Naivasha and Kingara roads, easing congestion at a junction that has long been one of Nairobi’s biggest traffic bottlenecks.

The project was financed through a Sh3.58 billion concessional loan from the Government of Spain’s Corporate International Fund. The loan terms — a 35-year repayment period, a 20-year grace period, and an interest rate of 0.01 percent — required the works to be executed by a Spanish contractor.

Centunion Company, which previously built the T-Mall flyover on Lang’ata Road and footbridges along Lang’ata Road and Raila Odinga Way, was awarded the contract.

President Ruto said the flyover would reduce travel times along the corridor by up to 60 per cent, arguing that congestion has consequences beyond transport. “Congestion is not merely a transport challenge. It is an economic challenge,” he said during the commissioning of the project.

The scope of works also included street lighting upgrades, improved drainage to reduce localised flooding, and landscaping around the project footprint — standard mitigation measures that KURA has applied on comparable grade-separation projects.

Site progress reports from January 2026 indicated that steel superstructure works were largely complete by that stage, with much of the erection carried out at night to limit disruption to traffic and adjacent businesses, including Junction Mall itself.

The flyover forms part of a broader pipeline of Nairobi road upgrades the government has flagged ahead of Kenya’s co-hosting role at the 2027 Africa Cup of Nations.

These include the Sh3 billion Upper Hill-Kenyatta Avenue viaduct, currently about 60 percent complete; a Sh1.6 billion upgrade to State House Road; Sh3.9 billion in access roads serving Talanta Sports City; and a Sh45 billion Intelligent Transport System intended to manage signalling at more than 210 junctions citywide.

KURA has not yet indicated whether additional NMT (non-motorised transport) elements will be retrofitted along the corridor pending progress of the Lesuuda NMT Bill currently before Parliament, which would mandate such infrastructure on urban and peri-urban roads nationally.
