Mixed methods designs which include both qualitative and quantitative were used. The participants of the study were household heads of project affected communities, the road construction project staff of Mizan-Dima Road construction project site. Purposively selected road section was taken from project stretch and all households from selected section were participated in the study. In order to collect the data the researcher developed survey questionnaire, semi structured interview, focused group discussion guiding questions. Secondary data were also included. Most of the participants were suggested that the road construction project has positive impacts in enhancing economic or livelihoods activities of the local communities’. Another majority of the participants reported the road construction has caused soil erosion, environmental pollutions and faunas and floras disruption. Meanwhile, adverse impacts from project’s selected material extraction and processing sites like quarry and borrow sites, crusher and asphalt plant have also disturbed the surrounding communities convenience. Generally, the finding shows that there are negative road construction effects in Mizan-Dima. Therefore, prevention and mitigation measures are vital in order to enhance the positive impacts and mitigate the adverse project induced social and environmental impacts on water resources, wildlife species, soil erosion, sound pollution, livelihood and other related impacts. Moreover, the contractor should comply the basic principles of EIA and implement the Environmental management plan appropriately to the ground during construction to minimize the negative impacts of the project. Future researches should endeavor to examine how to mitigate the impacts of road construction projects.enEnvironment, Social, Impacts, Road, Road construction, Mizan-DimaThesis
