I'm not sure if this is the right page for this, but I wanted to share an interesting mock-up Cushman + Wakefield created for turning the Central Loop into a more active neighborhood. I think it's a great idea, but not sure how feasible it would be.
I think it's in the city's long-term best interest to make the Loop more live-able and extend the energy from River North and West Loop and Michigan Avenue to the downtown areas that feel completely dead after 7pm and weekends.
