The Danville L&N Railroad Bridge Houston County, Tennessee The railroad town of Danville was established in 1861 and was flooded with the creation of Kentucky Lake in the 1940s. The railroad bridge that traveled over the Tennessee River was no longer in use in the 1980s and three spans of the bridge were removed. Today, it’s a strange sight. All that exists are two large spans of the bridge that extend into the lake. The bridge stops, ends and goes nowhere.
