The 159th Street Corridor Plan was initiated by the Village of Orland Park and has been funded by the Illinois Department of Transportation (IDOT) to establish coordinated transportation, urban design and economic development strategies to improve 159th Street between I-355 and I-294. Six municipalities along the Corridor are cooperating in this planning effort, which addresses a range of relevant planning issues, including coordination of marketing efforts, improvements to circulation and access, urban design concepts, and common branding and wayfinding strategies. The six participating municipalities include (from west to east): Homer Glen, Orland Park, Orland Hills, Tinley Park, Oak Forest and Markham.
