Salt Lake City's Gateway District air quality reflects the downtown mixed commercial and residential development adjacent to the Jordan River Parkway, with vehicle traffic on 400 West and the surrounding commercial character contributing local sources. The Salt Lake Valley's winter inversion problem affects all valley communities, while the Jordan River corridor provides limited ventilation and the district generally maintains moderate Salt Lake City metropolitan readings throughout most of the year.
