Louisville's Highlands air quality reflects the vibrant Bardstown Road corridor, with vehicle traffic on Bardstown Road and the surrounding dense mixed residential and commercial character contributing local sources. The neighbourhood's walkable character and the tree-lined streets provide limited natural filtration, while the flat Ohio Valley terrain allows reasonable dispersal and the Highlands generally maintains moderate Louisville metropolitan readings throughout most of the year.
