Will the recommended additional lanes result in increased air pollutant emissions and decreased air quality in southeastern Wisconsin?
The recommended additional lanes are expected to have a negligible impact on the level of transportation system ozone-related and other air pollutant emissions and air quality. This is because similar levels of regional vehicle traffic are expected with or without the additional lanes, only more or less under congested conditions and on freeways as opposed to surface arterials. In fact, transportation system ozone related air pollutant emissions have been significantly declining and are projected to continue to decline even with increasing traffic.
