This abandoned bridge is commonly called the Snake Bridge, but is also known as Schuster Bridge.

It was an old Illinois Route 4 bridge, which became the original Route 66 alignment in 1926. In 1930, the bridge was abandoned when the new Route 66 alignment was opened.

The bridge gets its name from the harmless, but endangered Kirtland snakes (Clonophis kirtlandii), that live under and around the bridge. The bridge and area is now a protected wildlife preserve. It's also part of a walking and biking path.
