Assessment of Air Quality Impact of a Proposed Section of Interstate 66

Report No: 71-R24

Published in 1972

About the report:

This report presents an assessment of the impact of a proposed section of Interstate 66 on the quality of the air in the immediate area of the project and in adjacent areas. The proposed project begins with an extension of existing I-66 at the interchange on I-495 in Fairfax County, passes through Arlington County, and terminates near the Key Bridge. Because of the limited time available for the assessment, consideration was given to only the most abundant gaseous pollutant emitted by motor vehicles, namely, carbon monoxide (CO). The assessment includes: (1) a mesoscale analysis of the effect of the proposed highway on the total CO emissions for the area, and (2) a microscale or corridor analysis to estimate the CO concentrations to be expected in some immediate areas of the project after its completion.
