Lagos took another concrete step this week toward unlocking African Development Bank financing for its long-anticipated Green Line rail corridor, even as transport analysts warned that the project’s current design may leave it underbuilt for the demand it is meant to serve.
The Lagos Metropolitan Area Transport Authority (LAMATA) confirmed on Friday that it has begun the AfDB’s formal appraisal process for the Lagos Rail Mass Transit (LRMT) Green Line, a milestone that brings the state closer to securing external funding for one of its most ambitious infrastructure undertakings in years.
The appraisal process opened with a high-level stakeholder engagement at the Lagos Oriental Hotel in Victoria Island, convened jointly by LAMATA and the Ministry of Finance Incorporated (MOFI).
The session drew senior government officials, AfDB representatives, private sector players, traditional rulers, community leaders, and residents from along the proposed rail corridor a cross-section of voices the authority says it intends to keep engaged as the project advances.
The gathering was not ceremonial. It forms part of the AfDB’s due-diligence mission, through which the bank will examine the environmental, social, and institutional dimensions of the project before deciding whether to greenlight financing.
In development-finance terms, this is the stage where a project either proves it is bankable and responsibly designed or runs into the kinds of red flags that can delay or derail funding decisions.
LAMATA used the forum to walk stakeholders through the project’s proposed alignment, its implementation strategy, and the thornier logistics of land acquisition, compensation, and traffic management during construction issues that, in past Lagos infrastructure projects, have often proven as consequential as the engineering itself.
While the appraisal technically covers the Green Line in its entirety, the immediate focus is Phase 1A, a stretch running from the Lekki First Toll Gate to Sangotedo. It is arguably the most consequential segment of the entire line: the Lekki-Epe corridor has grown explosively over the past decade, and traffic along it is now a defining frustration for residents and businesses alike.
LAMATA is positioning this phase as proof that rail can meaningfully cut commute times and support the corridor’s continued economic expansion.
Yet even as the financing process moves forward, a parallel conversation has emerged among transport and urban-planning specialists about whether the Green Line, as currently designed, is ambitious enough.
Independent transport researcher Tonami Playman has been among the most vocal critics. He has pointed out that the proposed alignment allows for just a single station in Victoria Island, a commercial and residential hub dense enough, in his view, to justify additional stops along Ahmadu Bello Way and Ozumba Mbadiwe Avenue.
Playman has also pressed for more stations along the Lekki corridor itself and raised a more technical objection: the decision to run eight-car B-size trains rather than larger ten-car sets, which he warns could leave the line struggling to absorb ridership growth in the years after launch.
Hannah Kates, Head of Open Data at Stears and a former urban planner with New York City’s Department of City Planning, has raised a related concern about the placement of the Civic Centre station, which she argues sits too far from many of Victoria Island’s busiest commercial and residential clusters.
Wide gaps between stations, she cautions, tend to work against the very ridership the line needs to justify its cost; commuters are less likely to use rail if getting to a station becomes its own inconvenience.
Taken together, the experts’ critique is less a rejection of the project than a call for refinement: tighter station spacing, better integration with Lagos’s existing rail network, and rolling stock sized for future demand rather than launch-day ridership.
They acknowledge such changes would raise costs but argue that under-designing the line now could prove more expensive in the long run, in the form of a rail system that Lagosians end up bypassing in favor of the road congestion it was built to solve.
For now, the project remains in AfDB’s hands. The bank’s appraisal team will weigh what it heard from corridor communities and institutional stakeholders against its own environmental and social safeguard standards before making a financing determination.
LAMATA, for its part, has signaled it intends to keep the consultation process running rather than treating Friday’s forum as a box-ticking exercise, a posture that will be tested as the project moves from planning meetings to the more difficult terrain of land acquisition and construction along one of Lagos’s busiest corridors.
Whether the concerns raised by Playman, Kates, and other observers make their way into a revised design before financing is finalized remains an open question, one that will likely shape how well the Green Line performs once trains actually start running.
WHAT YOU SHOULD KNOW
Lagos’s Green Line is moving forward on financing; AfDB appraisal is underway, and Phase 1A (Lekki Toll Gate to Sangotedo) is the immediate priority, but experts warn the current design (too few stations, smaller trains) risks under-serving demand once it’s built.
The real question isn’t whether the line gets funded, but whether it gets fixed before construction locks in a design that could leave Lagosians stuck in traffic anyway.
