1. Chain of Rocks Bridge
Spanning the Mississippi River and connecting Illinois and Missouri, the historic Chain of Rocks Bridge carried drivers across the water to avoid traffic in downtown St. Louis until a new bridge was built in 1967. Standing 55 feet above water and slightly curved, the bridge has remained unaltered since it was put out of commission. It is still open to bikers and pedestrians today.
2. Kan-O-Tex Service Station
Once a service station for motorists traveling Route 66, the Old Kan-O-Tex in Galena, Kansas, has undergone several changes throughout its history. It was first restored by four women into a tourist attraction named Four Women on the Route, but this diner and souvenir store is now called Cars on the Route for its association with the classic Pixar movie "Cars."
3. The blue whale
Built by Hugh S. Davis, this blue whale is the most famous landmark in Catoosa, Oklahoma. The 80-foot-long, 20-foot-tall iron and cement whale was built as an accompaniment to Davis’ pond. Visitors can walk on the whale, visit a nearby picnic area along the beach, and enjoy other attractions on-site.
