The CTA recently commissioned another group of artists to create new artworks for eight recently rehabbed train stations. Their creations will become part of the CTA’s ever growing collection of public art works in CTA facilities throughout the city - around 50 at last count. We asked commuters what impact art has on their daily commute, and talk with Elizabeth Kelley who heads up the CTA’s public art program. (Photo: Flickr/Cylon8)
