Detroit's abandoned tunnel systems open door to another world

Below Detroit's streets is a network of tunnel systems almost as elaborate as the bustling metropolis that sits above it. While most of the tunnels are now abandoned and closed off to the public, learning about these labyrinths can contextualize the city's importance on the national level. Below ground, an elaborate tunnel system connected the Fisher to New Center and General Motors buildings to ease employee commute. The tunnels are open today, though all of the once bustling storefronts are now shuttered. A tunnel system connects each of the hospitals making safe, seamless travel for patients and medical employees alike. The steam is also used to cook hot dogs at Lafayette Coney Island and brew beer at Detroit Beer Co. A tunnel of psychedelic lights connects Detroit Metropolitan Airport's A and B/C Councourses to an original soundtrack. Located in McNamara Terminal, the Light Tunnel is nearly 800 feet long and illuminated by 9,000 feet of glass panels and LED lighting - as a moving walkway carries passengers through the tunnel.
