The 606, also known as the Bloomingdale Trail, is a 2.7-mile elevated park and multi-use trail in Chicago, built on a former rail line. It connects several neighborhoods on the city's west side, offering green space, walking, biking, and recreational areas. The 606 features gardens, art installations, and spectacular views of the surrounding areas, fostering community engagement and providing a safe, accessible space for outdoor activities. The project has revitalized previously underused urban space, creating a vibrant pathway that links parks, cultural hubs, and local businesses.
