Moodna Viaduct, opened in 1909, is an iron railroad trestle in Cornwall, New York, near the village of Salisbury Mills. It spans Moodna Creek and its valley north of Schunemunk Mountain. The trestle spans the valley for 3,200 feet and is 193 feet high at its highest point which makes it the highest and longest railroad trestle east of the Mississippi River.
The Viaduct carries Metro-North's Port Jervis commuter line and Norfolk Southern freight trains. The Viaduct is a tourist attraction for the small town of Salisbury Mills for it creates a spectacular landscape and is particularly popular during the fall foliage season. Trivia: The Moodna Viaduct appears as a prominent feature in the 2007 film Michael Clayton. Seen here is the on-time Salisbury Mills 9:32 train heading south to Hoboken, New Jersey.
