The Tulip Viaduct is a 2295feet long railroad bridge (also known as the Greene County Viaduct or Tulip Trestle, and officially designated Bridge X76-6) in Greene County, Indiana, that spans Richland Creek between Solsberry and Tulip. According to Richard Simmons and Francis Haywood Parker, authors of Railroads of Indiana, it is "easily the state's most spectacular railroad bridge". The bridge was built in 1905 and 1906 by the Indianapolis Southern Railway and successor Indianapolis Southern Railroad, which became part of the Illinois Central Railroad in 1911. It is now part of the Indianapolis–Newton, Illinois, line of the Indiana Rail Road.
Work on the bridge started on May 22, 1905, when a groundbreaking ceremony was led by Joe Moss. It was finished in December 1906 and, at that time, was the longest rail trestle in the United States and the third longest bridge of its kind in the world. It has 18 towers for support. Other trestles constructed since that time are longer, such as the Hi-Line Railroad Bridge in Valley City, North Dakota, which is long.
The original cost of the viaduct was $246,504 which is an estimated $20 million in 2020 dollars. This massive structure was built using mostly Italian immigrant laborers. [1] The laborers were paid up to 30 cents an hour, which was considered to be an excellent wage in 1906. The viaduct was constructed by Indianapolis Southern Railway and secretly financed by Illinois Central Railroad. It was built for train travel to transport coal from Greene County mines to large cities, such as Chicago. Passenger trains once traveled across the viaduct, but passenger service was discontinued in 1948.[2]
According to a placard that used to be attached to the western side of the bridge (underneath the tracks on a large I-beam), the bridge was constructed by the New York Bridge Company, not the Indianapolis Southern Railway or its successor the Indianapolis Southern Railroad. In 2004 or earlier, the placard had been removed. Two 45feet sections were added to the bridge in 1916. Other than that, the bridge is as it was when it was originally constructed.
Over the years, a large amount of graffiti has been spray-painted on the trestle, especially at the base of the towers nearest the road. The Indiana Rail Road has retained the graffiti: the thickness of the paint prevents rain and snow from rusting the metal, thus preserving the structure.
The bridge is 2295feet long and is 157feet above the ground at its highest point. It was built using of steel and is composed of individual 40feet and 74feet spans supported by eighteen towers.[3]
