The ECS Bridge over Big Goosse Creek was constructed in 1914. 

The Canton Bridge Company of Canton, Ohio was awarded the construction contract by Sheridan County in June 1914 for four steel bridges - this and another span over Big Goose Creek (a 40' span over North Piney Creek south of Sheridan) and another. With the low bid of $4800 for all four, Canton had underbid several other national bridge erectors; the Elkhart Bridge and Iron Company, Midland Bridge Company, Clinton Bridge Company, Gregg and Stout, Missouri Valley Bridge and Iron Company, Security Bridge Company, Minneapolis Steel and Machinery Company and Walsh and Patterson. The bridges were completed by November of that year. This small four-panel Pratt pony is an excellent early example of a roadway truss configuration which is common for Wyoming.
