In the late 19th and early 20th Centuries, interurban railroads began to develop throughout the United States. These electrified railroads were intended to provide efficient passenger service, generally to suburban or rural areas. At the same time, electrified street railways began to develop in larger cities throughout the United States. These trolleys provided service to passengers, primarily in urban areas. Champaign businessman William B. McKinley sought to join these two modes of transportation. McKinley desired to construct electrified railroad connecting major cities in central Illinois. The Illinois Traction System (ITC) was formed to develop this network, and the ITC began purchasing railroads in 1899. McKinley incorporated the Decatur, Springfield & St. Louis Railway (DS&StL) in 1903, intended to connect the namesake cities. The Decatur Street Railway & Light Company was purchased the same year, which operated a system of streetcars in Decatur, and had been constructed during the 1890s. Between Springfield and Decatur, a defunct right-of-way was purchased. The line to Springfield opened to traffic in 1904.
The DS&StL was renamed the St. Louis & Springfield Railway (StL&S) in 1903, and a second subsidiary, the St. Louis North Eastern Railway (StLNE) was created the same year. The railroad opened to East St. Louis in 1906, utilizing the Terminal Railroad Association of St. Louis (TRRA) to reach St. Louis. A bridge across the Mississippi River to reach St. Louis was completed by subsidiary St. Louis Electric Traction Railway in 1910, completing the western portion of the route. Much of the route paralleled existing railroad lines, particularly between Decatur and Springfield. Branch lines were later constructed to mines near Hillsboro, as well as into Alton, Edwardsville, and Mechanicsburg. The ITC saw unprecedented freight success along the system, and became the largest and most profitable interurban system in the United States. During the early and mid-20th Century, interurbans fell out of favor with the introduction of the automobile. In 1937, the railroad would be reorganized as the Illinois Terminal Railway. The railroad remained profitable long after many other interurbans had been abandoned. Post-World War II, the railroad remained profitable, comparable to regional sized railroads in the midwest. The ITC would be acquired by nine larger railroads in 1956, with most of the system abandoned. The ITC continued to operate trackage in the St. Louis area, while other portions of the system were reused by freight railroads. The ITC would become part of the Norfolk & Western Railway in 1982, which immediately became part of the Norfolk Southern Railway. Today, much of the ITC system has been abandoned. Short segments near Alton and East St. Louis continue to be used by Norfolk Southern, as well as a short section near Illiopolis.
Located on the west side of Decatur, this deck plate girder viaduct carries the former Illinois Traction Railroad over Stevens Creek in Fairview Park. Work on the structure began in December 1903, and continued through the spring of 1904. As part of the work, a large embankment was constructed to carry the railroad across the Stevens Creek Valley. A large bridge would be required to cross the creek, which would be located at the west end of a sweeping curve. The bridge consists of one 60-foot, two 45-foot and two 25-foot deck plate girder spans, set onto steel towers and concrete abutments and pedestals. The deck plate girder spans use a typical design, with moderately heavy girders and a light interior bracing. Typical of viaducts of this design, the main span is slightly deeper than the tower and approach spans. The towers are constructed of laced steel beams, connected by pinned connections. Chicago Engineering & Construction Company reportedly had the contract for concrete work on the structure. It is believed that the Lafayette Bridge Company fabricated the superstructure, as this company fabricated the superstructures for other steel bridges on the Decatur to Springfield line.
Deck plate girder viaducts were the preferred bridge design for tall bridges, as they were the most cost effective and strongest design. These bridges typically consist of deck plate girder main spans, and tower spans of the same design which are set above steel towers. Tall steel towers were far more economical to construct than large concrete piers. Prior to the abandonment of the ITC, the bridge was repaired by adding vertical steel beams at the abutments, which helped support the 45-foot spans. After the ITC was abandoned, the bridge was acquired by the City of Decatur, and converted to a pedestrian trail. Since then, the bridge has seen only minor alterations. The original concrete substructures were repaired by encasing them in concrete in the 2010s. Overall, the bridge appears to be in fair to good condition, with no significant deterioration noted. The viaduct is now a landmark in Fairview Park, and is part of a popular recreation trail. The author has ranked the bridge as being moderately significant, due to the structure being one of the few remaining bridges from the ITC.
