This large Pratt Through Truss is visible from 9th Avenue in the town of Winfield.
Built in 1905, this truss follows a standard design. It consists of a 7-panel, pin connected Pratt Through Truss Span. It was approached by trestle spans.
In 1919, a second parallel truss would be added for southbound (eastbound) track. This new truss followed the plans of the 1905 span exactly, which makes this one of the most modern pin connected railroad trusses of this size.
Up until approximately 2003, the approaches to the structure were built of trestle spans. In 2003, the entire north approach and the south approach of the southbound track was replaced with modular concrete girder spans. The trusses currently sit on concrete piers, while the new approaches are supported by steel piles.
Overall, the bridge remains in good condition. The bridge sits on concrete and concrete pile substructures. Along with Bridge #1, this is the most used bridge in Winfield.
