The Starrucca Viaduct still carries trains today, in continuous use since it was built in 1847-48. It is in far northeastern Pennsylvania along with other notable viaducts in Nicholson and Kingsley. It was built by Irish immigrants.
It crosses a wide creek valley at a height of one hundred feet, its 17 arches spanning over one thousand feet, and it is twenty-five feet wide, carrying two sets of tracks.
It is a beautiful and graceful structure. It is listed as a National Register of Historic Engineering Landmark and is on the National Register of Historic Places.
There are many images to be seen via Google including historic photos and paintings, and aerial photos.
