Every road investment has both positive and negative consequences in spatial, economic, environmental, and social terms. The objective of the article is the social assessment of the effect of construction of the Southern Warsaw Ring Road (WRR) on: (i) the quality of life of the local community, and (ii) the residential real estate market. The analyses employed the method of quantitative analysis with the application of the survey technique. The questionnaire was made publicly available to residents of the Wilanów district in Warsaw. Results obtained in the scope of the study render decision making models of respondents depending on the distance of the place of residence from the WRR. The results reveal that responses given by the group of respondents living nearer the ring road are the most variable, particularly in the context of assessing the effect of the investment on the quality of life, including nuisance related to the express road and plans to change the place of residence. The same group of respondents provided the highest share of responses supporting the claim that housing prices increased due to the construction of the ring road.
