The Atherton Bridge is a historic iron truss bridge in Lancaster, Massachusetts, spanning the South Branch of the Nashua River. It is a rare example of a hybrid pony truss that is similar to the 19th century truss design of Simeon S. Post. It was built by J. H. Cofrode & Co. of Philadelphia in 1870. It was the first iron bridge to be constructed in the town. The bridge was added to the National Register of Historic Places in 1979. Read more on Wikipedia
