Spanning 2,375 feet with a height of 240 feet, the Tunkhannock Viaduct is truly a sight to see. This magnificent concrete bridge was part of the Delaware Lackawanna Railroad and was built in the town of Nicholson, PA, just 12 miles from our Gibson hotel. Compare this structure to the Starucca Viaduct built in nearby Lanesboro, PA made from PA bluestone it was erected in 1847 against all odds!
