The paper aims at assessing effective demand of toll roads in the context of user demand and willingness-to-pay (WTP). The specific objectives are to establish mitigation costs associated with existing roads, to find out users’ involvement in project planning and what an average user will be willing to pay for improved road conditions. Using a sample of 500 observations, with a response of 356 (71.2%), effective demand for toll roads and willingness-to-pay along Lekki-Ajah corridor (Lekki toll road concession) in Lagos was investigated. Data was analyzed using descriptive statistics, and the discounted cash flow technique to ascertain project viability. The result of the analysis shows that majority of the respondents and commuters complained of not being consulted at the planning stage of the project, which affected the viability and willingness to pay (WTP) figures. Also, commuters suffer consequential damages and delay in travel time due to poor road conditions. Stakeholder consultation in infrastructure planning and provision is rarely undertaken in Nigeria. This paper is therefore designed to expose the implication of this practice to successful Public-Private-Partnership.
