Chain of Rocks Bridge (St. Louis, Missouri)
The Chain of Rocks Bridge, constructed in 1929, is renowned for its distinctive 22-degree bend, a design necessitated by the presence of water intake structures and uneven bedrock beneath the Mississippi River. This unique feature distinguishes it from other river crossings. Originally part of Route 66, the bridge now serves as a pedestrian and cycling route, offering scenic views and a glimpse into its engineering significance. (nps.gov)
