ABSTRACT. Assessing the impact of the highway 25 expansion project on air quality in montreal using gis. The aim of the paper is to assess local air pollution implications of the Highway 25 expansion project from Montreal. The basic concept of the roadway air dispersion model consists in calculating air pollutant levels in the vicinity of a highway by considering it as a line source. To fulfill this assessment, GIS software was used in order to determine pollutant distribution around the study area based on data collected by existing air monitoring stations located in the City of Montreal. GIS interpolation methods, notably Kriging and Inverse Distance Weighted (IDW), was used to generate maps of pollutant concentrations across the study area. From the results, recommendations will be made in regards to the project and appropriate mitigatory alternatives suggested.

     Key words: GIS for EIA, traffic pollution, air quality
