The Mombasa–Nairobi–Kampala Corridor: Africa's Busiest Trade Route Gets a Reboot
The Northern Corridor handles over $5 billion in annual freight between the Indian Ocean and the Great Lakes region. New investments are transforming throughput, but bottlenecks persist.
Stretching 1,700 kilometres from Mombasa's deep-water harbour to the landlocked capitals of Kampala, Kigali, and Bujumbura, the Northern Corridor is the economic spine of East Africa. It carries over 80% of Uganda's imports, virtually all of Rwanda's sea-going freight, and substantial volumes for Eastern DRC and South Sudan.
In 2023, the corridor handled an estimated 26 million tonnes of cargo, a 9% increase on 2022. That growth, driven by expanding regional trade volumes and new consumer markets, is straining infrastructure that was designed for a fraction of current demand.

Mombasa Port: Capacity Under Pressure
Kenya Ports Authority processed 1.64 million TEUs (twenty-foot equivalent units) at Mombasa in 2023, its highest ever throughput. The Kipevu Container Terminal, which opened its second berth in 2021, has provided meaningful relief. A third berth, currently under construction with Chinese financing, is due online in 2026 and will push capacity to over 2 million TEUs annually.
Congestion, however, remains a persistent problem. Average dwell time for imports, the duration containers sit in the port before being collected, stands at 5.2 days, compared to a global benchmark of 3 days. Poor digitisation of customs processes and fragmented logistics documentation are the primary culprits. The Kenya Revenue Authority has rolled out its integrated customs system, iCMS, across all entry points, but full adoption by clearing agents has been slower than planned.
Standard Gauge Railway: Game-Changer or White Elephant?
The Standard Gauge Railway, which runs from Mombasa to Naivasha, was conceived as a transformative upgrade to corridor freight capacity. The reality has been mixed. The SGR has undeniably reduced transit time from Mombasa to Nairobi, from 8+ hours by road to under 5 hours by rail. But freight volumes have consistently fallen short of projections, partly because the line terminates at Naivasha rather than the Ugandan border, requiring transshipment to road at that point.
Extension of the SGR to Kampala, originally planned for 2023, has been delayed indefinitely due to financing shortfalls. Until that extension happens, most freight operators still prefer road, despite its higher cost and longer time, because it offers door-to-door delivery without transshipment.
One-Stop Border Posts
The most impactful short-term efficiency gain has come from One-Stop Border Posts. The Malaba OSBP between Kenya and Uganda, now processing over 800 trucks per day, has reduced average border crossing time from 3 days to under 12 hours for compliant consignments. Similar OSBPs at Busia and Namanga are delivering comparable results.
The goal is to replicate this model at all major corridor crossing points by 2027.
