MTA New York City Transit reopened the 28 St station on the 6 line on Monday, January 14, 2019, after a months-long station repair and modernization project. While crews made extensive repairs to the station's structural steel, they also upgraded and modernized the station infrastructure such as turnstile areas, digital signage and station entrances.

MTA Arts & Design commissioned "Roaming Underfoot," a series of four glass mosaic murals by artist Nancy Blum for the station platforms to celebrate the station and the neighborhood above, which includes nearby Madison Square Park. The artwork depicts seven flowering plants that are sourced from the Madison Square Park Conservancy’s Perennial Collection to represent plants that withstand the city's changing climate: Red Buds, Magnolias, Hellebores, Witch Hazel, Daffodils, Hydrangea and Camellia.

Bloom’s intent was to capture Madison Square Park's role as an urban sanctuary and to enhance the station environment. Known for her detailed floral studies, Blum transforms the study of botany into bold and expressive statements of art.
