The area around Bennington played an important role in the westward expansion of the United States. The Missouri and Platte Rivers were important travel corridors for indigenous peoples, early explorers, trappers, and pioneers. Railroads revolutionized travel and led to the creation of hundreds of small villages along the rail lines; Bennington, founded in 1887, was one of these villages. The arrival of the automobile and better roads decreased the dependency on rail service. By 1975, the rail line that created Bennington had been abandoned. Bennington benefitted from upgraded roads and highways and from suburban sprawl. In the meantime, the Washington community declined, eventually closing its school and church.
