Public-Private Partnerships (PPP) and Major Infrastructure in Lagos

Lagos State actively promotes public-private partnerships (PPP via the Office of Public-Private Partnerships) to design, build, and operate its expressway bridges, rail lines, and waste treatment infrastructure.

Flagship Projects Open to Investors

The fourth mainland bridge (4th Mainland Bridge), a project intended to connect Lagos Island/Ikorodu to Lekki along a route still being financially structured, illustrates the scale of private capital needed to decongest a city where existing bridges (Third Mainland Bridge, Eko Bridge, Carter Bridge) are structurally overloaded. Concessioned toll roads, following the model already in place on certain stretches of the Lekki-Epe Expressway, allow private concessionaires to finance construction in exchange for toll rights over several decades. The LAGFERRY network and the expansion of lagoon jetties represent another investment avenue, as the waterway remains underused relative to its potential for relieving pressure on the road network.

Legal Structuring and Return on Investment

Lagos PPPs are structured by the Lagos State Office of Public-Private Partnerships (OPPP), which oversees BOT (Build-Operate-Transfer) arrangements or long-term concessions, with state guarantees covering land and, in some cases, minimum guaranteed traffic volumes. For an investor, the appeal of these projects lies in the visibility of revenue streams over 20 to 30 years (tolls, ferry fares, fees), but it requires a rigorous analysis of political risk and currency risk, since revenue is collected in Naira while initial financing is often raised in hard currency.

A 38 km Project with Complex Financing Arrangements

The Fourth Mainland Bridge route runs roughly 38 kilometers, connecting Lagos Island to Ikorodu via Langbasa (Lekki) and Baiyeku, at a total estimated cost of $2 to $2.5 billion, or around N844 billion. Financing was initially expected to come from a consortium including the Africa Finance Corporation, Access Bank, and other private investors, with Visible Assets Limited as the coordinating structure, but the project has faced years of delays, with prospective financiers demanding a sovereign guarantee from the federal government before committing capital.

A Project Still in the Study Phase

Despite funds allocated in Lagos State's 2025 budget for technical studies and urban renewal work linked to the project, actual construction had still not started as of early 2026, with the state having spent around N220.7 million during the year without work breaking ground. This illustrates the risk profile typical of Lagos's major infrastructure projects: substantial financing needs and clear political will, but financial structuring and guarantee negotiations that can stretch over several years before the first shovel goes into the ground.
