The city's Percent for Art program works to place artwork throughout the city. The transportation enhancement program, which works to beautify roadway areas, includes such projects as the mural at Belt Line and I-30, the bas reliefs on State Highway 161 and the new bridge over the Union Pacific Railroad at Main Street and Belt Line. Programs such as these prevent litter, because they encourage beautiful spaces. Statistics show that if a community beautifies itself, litter will decrease. View photos of public art in Grand Prairie.
