![Union Pacific 4139 leads Norfolk Southern 196 across High Bridge on November 8th, 2022, as it heads north across the Kentucky River on the NS CNO&TP First District (Short Line).
According to Wikipedia: The High Bridge is a railroad bridge crossing the Kentucky River Palisades, that rises approximately 275 feet from the river below and connects Jessamine and Mercer counties in Kentucky. Formally dedicated in 1879, it is the first cantilever bridge constructed in the United States. It has a three-span continuous under-deck truss used by Norfolk Southern Railway to carry trains between Lexington and Danville. It has been designated as a National Historic Civil Engineering Landmark.
In 1851, the Lexington & Danville Railroad, with Julius Adams as chief engineer, retained John A. Roebling to build a railroad suspension bridge across the Kentucky River for a line connecting Lexington and Danville, Kentucky west of the intersection of the Dix and Kentucky rivers. In 1855, the company ran out of money and the project was resumed by Cincinnati Southern Railroad in 1873 following a proposal by C. Shaler Smith for a cantilever design using stone towers designed by John A. Roebling (who designed the Brooklyn Bridge).
The bridge was erected using a cantilever design with a three-span continuous under-deck truss and was opened in 1877 on the Cincinnati Southern Railway. It was 275 feet (84 m) tall and 1,125 feet (343 m) long: the tallest bridge above a navigable waterway in North America and the tallest railroad bridge in the world until the early 20th century. Construction was completed using 3,654,280 pounds of iron at a total cost of $404,373.31. In 1879 President Rutherford B. Hayes and Gen. William Tecumseh Sherman attended the dedication.
After years of heavy railroad use, the bridge was rebuilt by Gustav Lindenthal in 1911. Lindenthal reinforced the foundations and rebuilt the bridge around the original structure. To keep railroad traffic flowing, the track deck was raised by 30 feet during construction and a temporary trestle was constructed.[6] In 1929, an additional set of tracks was built to accommodate increased railroad traffic and the original limestone towers were removed.
