The pioneering 30-year concession for Lekki-Epe Expressway Toll Road was Nigeria’s first ever Public Private Partnership (PPP) project. The project comprised the rehabilitation and upgrade of 49 kilometres of existing two-lane dual carriageway to a three-lane highway, the introduction of three toll plazas (with a maximum 22 lanes/plaza) and the construction of a new 20 kilometres-long highway along the south coast of the Epe peninsula.
