Abstract: The Lagos State Government plans to construct a 19 km road network connecting Abule Ado to Ijegun-Ijegemo Alape canoe side. This initiative aims to alleviate traffic congestion along LASU/Iba road and address growing access needs in the area. An Environmental Impact Assessment (EIA) has been completed to assess the project's potential environmental and social effects, including strategies to mitigate negative impacts and enhance positive ones. Field surveys identified and documented environmental impacts, while consultations involved various stakeholders such as local authorities and affected individuals. The EIA adheres to Nigerian Government regulations and guidelines from the Federal Ministry of Environment and NESREA. The proposed route will traverse Abule Ado (Latitude 06.45789, Longitude 03.25520), Alape/Arandun (Longitude 06.50612, Latitude 03.20202), and Befun (Longitude 06.50686, Latitude 03.22934), reaching Ijegun Ijeododo (Longitude 06.50695, Latitude 03.27605). The project, located in the Ojo Local Government Area of Lagos, Nigeria, is designed to significantly improve local infrastructure and traffic flow. This work describes the issues that have been identified so far through the public participation process and one-on-one consultations with affected landowners by specialists on the project team. Similarly, mitigation measures will be proposed to reduce negative impacts and enhance positive impacts. The findings of the specialists will also be used to develop an Environmental Management Plan (EMP) that will guide the construction and operation of the proposed road project. The EMP will include a monitoring program to assess performance.
